 Bite the bullet and submit the patch to PostgreSQL, to add the t_cid to the WAL records. It makes the WAL records larger, which could make this unpopular in the PostgreSQL community. However, it might simplify some logical decoding code; Andres Freund briefly mentioned in PGCon 2022 discussion on Heikki's Neon presentation that logical decoding currently needs to jump through some hoops to reconstruct the same information.
 
-Update from Heikki (2024-04-17): I tried to write an upstream patch for that, to use the t_cid field for logical decoding, but it was not as straightforward as it first sounded.
 
 ### Alternatives
 Perhaps we could write an extra WAL record with the t_cid information, when a page is evicted that contains rows that were touched a transaction that's still running. However, that seems very complicated.

+first, then the page is filled, and finally the new page WAL-logged. But if multiple backends extend
+a relation at the same time, the pages can be WAL-logged in different order.
+
+I'm not sure what scenario exactly required this change in Neon, though.
+
+### How to get rid of the patch
+
+Submit patches to pgsql-hackers, to tighten up the WAL-logging around relation extension. It's a bit
+confusing even in PostgreSQL. Maybe WAL log the intention to extend first, then extend the relation,
+and finally WAL-log that the extension succeeded.

-### Problem we're trying to solve
-
-This change was made in v16. Starting with v16, when PostgreSQL extends a relation, it first extends
-it with zeros, and it can extend the relation more than one block at a time. The all-zeros page is WAL-ogged, but it's very wasteful to include 8 kB of zeros in the WAL for that. This hack was made so that we WAL logged a compact record with a whole-page "hole". However, PostgreSQL has assertions that prevent that such WAL records from being replayed, so this breaks compatibility such that unmodified PostreSQL cannot process Neon-generated WAL.

-# Graceful Restarts of Storage Controller Managed Clusters
-
-## Summary
-This RFC describes new storage controller APIs for draining and filling tenant shards from/on pageserver nodes.
-It also covers how these new APIs should be used by an orchestrator (e.g. Ansible) in order to implement
-graceful cluster restarts.
-
-## Motivation
-
-Pageserver restarts cause read availablity downtime for tenants.
-
-For example pageserver-3 @ us-east-1 was unavailable for a randomly
-picked tenant (which requested on-demand activation) for around 30 seconds
-during the restart at 2024-04-03 16:37 UTC.
-
-Note that lots of shutdowns on loaded pageservers do not finish within the
-[10 second systemd enforced timeout](https://github.com/neondatabase/aws/blob/0a5280b383e43c063d43cbf87fa026543f6d6ad4/.github/ansible/systemd/pageserver.service#L16). This means we are shutting down without flushing ephemeral layers
-and have to reingest data in order to serve requests after restarting, potentially making first request latencies worse.
-
-This problem is not yet very acutely felt in storage controller managed pageservers since
-tenant density is much lower there. However, we are planning on eventually migrating all
-pageservers to storage controller management, so it makes sense to solve the issue proactively.
-
-## Requirements
-
-- Pageserver re-deployments cause minimal downtime for tenants
-- The storage controller exposes HTTP API hooks for draining and filling tenant shards
-from a given pageserver. Said hooks can be used by an orchestrator proces or a human operator.
-- The storage controller exposes some HTTP API to cancel draining and filling background operations.
-- Failures to drain or fill the node should not be fatal. In such cases, cluster restarts should proceed
-as usual (with downtime).
-- Progress of draining/filling is visible through metrics
-
-## Non Goals
-
-- Integration with the control plane
-- Graceful restarts for large non-HA tenants.
-
-## Impacted Components
-
-- storage controller
-- deployment orchestrator (i.e. Ansible)
-- pageserver (indirectly)
-
-## Terminology
-
-** Draining ** is the process through which all tenant shards that can be migrated from a given pageserver
-are distributed across the rest of the cluster.
-
-** Filling ** is the symmetric opposite of draining. In this process tenant shards are migrated onto a given
-pageserver until the cluster reaches a resonable, quiescent distribution of tenant shards across pageservers.
-
-** Node scheduling policies ** act as constraints to the scheduler. For instance, when a
-node is set in the `Paused` policy, no further shards will be scheduled on it.
-
-** Node ** is a pageserver. Term is used interchangeably in this RFC.
-
-** Deployment orchestrator ** is a generic term for whatever drives our deployments.
-Currently, it's an Ansible playbook.
-
-## Background
-
-### Storage Controller Basics (skip if already familiar)
-
-Fundamentally, the storage controller is a reconciler which aims to move from the observed mapping between pageservers and tenant shards to an intended mapping. Pageserver nodes and tenant shards metadata is durably persisted in a database, but note that the mapping between the two entities is not durably persisted. Instead, this mapping (*observed state*) is constructed at startup by sending `GET location_config` requests to registered pageservers.
-
-An internal scheduler maps tenant shards to pageservers while respecting certain constraints. The result of scheduling is the *intent state*. When the intent state changes, a *reconciliation* will inform pageservers about the new assigment via `PUT location_config` requests and will notify the compute via the configured hook.
-
-### Background Optimizations
-
-The storage controller performs scheduling optimizations in the background. It will
-migrate attachments to warm secondaries and replace secondaries in order to balance
-the cluster out.
-
-### Reconciliations Concurrency Limiting
-
-There's a hard limit on the number of reconciles that the storage controller
-can have in flight at any given time. To get an idea of scales, the limit is
-128 at the time of writing.
-
-## Implementation
-
-Note: this section focuses on the core functionality of the graceful restart process.
-It doesn't neccesarily describe the most efficient approach. Optimizations are described
-separately in a later section.
-
-### Overall Flow
-
-This section describes how to implement graceful restarts from the perspective
-of Ansible, the deployment orchestrator. Pageservers are already restarted sequentially.
-The orchestrator shall implement the following epilogue and prologue steps for each
-pageserver restart:
-
-#### Prologue
-
-The orchestrator shall first fetch the pageserver node id from the control plane or
-the pageserver it aims to restart directly. Next, it issues an HTTP request
-to the storage controller in order to start the drain of said pageserver node.
-All error responses are retried with a short back-off. When a 202 (Accepted)
-HTTP code is returned, the drain has started. Now the orchestrator polls the
-node status endpoint exposed by the storage controller in order to await the
-end of the drain process. When the `policy` field of the node status response
-becomes `PauseForRestart`, the drain has completed and the orchestrator can
-proceed with restarting the pageserver.
-
-The prologue is subject to an overall timeout. It will have a value in the ballpark
-of minutes. As storage controller managed pageservers become more loaded this timeout
-will likely have to increase.
-
-#### Epilogue
-
-After restarting the pageserver, the orchestrator issues an HTTP request
-to the storage controller to kick off the filling process. This API call
-may be retried for all error codes with a short backoff. This also serves
-as a synchronization primitive as the fill will be refused if the pageserver
-has not yet re-attached to the storage controller. When a 202(Accepted) HTTP
-code is returned, the fill has started. Now the orchestrator polls the node
-status endpoint exposed by the storage controller in order to await the end of
-the filling process. When the `policy` field of the node status response becomes
-`Active`, the fill has completed and the orchestrator may proceed to the next pageserver.
-
-Again, the epilogue is subject to an overall timeout. We can start off with
-using the same timeout as for the prologue, but can also consider relying on
-the storage controller's background optimizations with a shorter timeout.
-
-In the case that the deployment orchestrator times out, it attempts to cancel
-the fill. This operation shall be retried with a short back-off. If it ultimately
-fails it will require manual intervention to set the nodes scheduling policy to
-`NodeSchedulingPolicy::Active`. Not doing that is not immediately problematic,
-but it constrains the scheduler as mentioned previously.
-
-### Node Scheduling Policy State Machine
-
-The state machine below encodes the behaviours discussed above and
-the various failover situations described in a later section.
-
-Assuming no failures and/or timeouts the flow should be:
-`Active -> Draining -> PauseForRestart -> Active -> Filling -> Active`

-All of them are safely retriable from the perspective of the storage controller.
-- 404: Requested node was not found
-- 503: Requested node is known to the storage controller, but unavailable
-- 412: Drain precondition failed: there is no other node to drain to or the node's schedulling policy forbids draining
-- 409: A {drain, fill} is already in progress. Only one such background operation
-is allowed per node.
-
-When the drain is accepted and commenced a 202 HTTP code is returned.
-
-Drains and fills shall be cancellable by the deployment orchestrator or a
-human operator via: `DELETE /v1/control/node/:node_id/{drain,fill}`. A 200
-response is returned when the cancelation is successful. Errors are retriable.
-
-### Drain Process
-
-Before accpeting a drain request the following validations is applied:
-* Ensure that the node is known the storage controller
-* Ensure that the schedulling policy is `NodeSchedulingPolicy::Active` or `NodeSchedulingPolicy::Pause`
-* Ensure that another drain or fill is not already running on the node
-* Ensure that a drain is possible (i.e. check that there is at least one
-schedulable node to drain to)
-
-After accepting the drain, the scheduling policy of the node is set to
-`NodeSchedulingPolicy::Draining` and persisted in both memory and the database.
-This disallows the optimizer from adding or removing shards from the node which
-is desirable to avoid them racing.
-
-Next, a separate Tokio task is spawned to manage the draining. For each tenant
-shard attached to the node being drained, demote the node to a secondary and
-attempt to schedule the node away. Scheduling might fail due to unsatisfiable
-constraints, but that is fine. Draining is a best effort process since it might
-not always be possible to cut over all shards.
-
-Importantly, this task manages the concurrency of issued reconciles in order to
-avoid drowning out the target pageservers and to allow other important reconciles
-to proceed.
-
-Once the triggered reconciles have finished or timed out, set the node's scheduling
-policy to `NodeSchedulingPolicy::PauseForRestart` to signal the end of the drain.
-
-A note on non HA tenants: These tenants do not have secondaries, so by the description
-above, they would not be migrated. It makes sense to skip them (especially the large ones)
-since, depending on tenant size, this might be more disruptive than the restart since the
-pageserver we've moved to do will need to on-demand download the entire working set for the tenant.
-We can consider expanding to small non-HA tenants in the future.
-
-### Fill Process
-
-Before accpeting a fill request the following validations is applied:
-* Ensure that the node is known the storage controller
-* Ensure that the schedulling policy is `NodeSchedulingPolicy::Active`.
-This is the only acceptable policy for the fill starting state. When a node re-attaches,
-it set the scheduling policy to `NodeSchedulingPolicy::Active` if it was equal to
-`NodeSchedulingPolicy::PauseForRestart` or `NodeSchedulingPolicy::Draining` (possible end states for a node drain).
-* Ensure that another drain or fill is not already running on the node
-
-After accepting the drain, the scheduling policy of the node is set to
-`NodeSchedulingPolicy::Filling` and persisted in both memory and the database.
-This disallows the optimizer from adding or removing shards from the node which
-is desirable to avoid them racing.
-
-Next, a separate Tokio task is spawned to manage the draining. For each tenant
-shard where the filled node is a secondary, promote the secondary. This is done
-until we run out of shards or the counts of attached shards become balanced across
-the cluster.
-
-Like for draining, the concurrency of spawned reconciles is limited.
-
-### Failure Modes & Handling
-
-Failures are generally handled by transition back into the `Active`
-(neutral) state. This simplifies the implementation greatly at the
-cost of adding transitions to the state machine. For example, we
-could detect the `Draining` state upon restart and proceed with a drain,
-but how should the storage controller know that's what the orchestrator
-needs still?
-
-#### Storage Controller Crash
-
-When the storage controller starts up reset the node scheduling policy
-of all nodes in states `Draining`, `Filling` or `PauseForRestart` to
-`Active`. The rationale is that when the storage controller restarts,
-we have lost context of what the deployment orchestrator wants. It also
-has the benefit of making things easier to reason about.
-
-#### Pageserver Crash During Drain
-
-The pageserver will attempt to re-attach during restart at which
-point the node scheduling policy will be set back to `Active`, thus
-reenabling the scheduler to use the node.
-
-#### Non-drained Pageserver Crash During Drain
-
-What should happen when a pageserver we are draining to crashes during the
-process. Two reasonable options are: cancel the drain and focus on the failover
-*or* do both, but prioritise failover. Since the number of concurrent reconciles
-produced by drains/fills are limited, we get the later behaviour for free.
-My suggestion is we take this approach, but the cancellation option is trivial
-to implement as well.
-
-#### Pageserver Crash During Fill
-
-The pageserver will attempt to re-attach during restart at which
-point the node scheduling policy will be set back to `Active`, thus
-reenabling the scheduler to use the node.
-
-#### Pageserver Goes unavailable During Drain/Fill
-
-The drain and fill jobs handle this by stopping early. When the pageserver
-is detected as online by storage controller heartbeats, reset its scheduling
-policy to `Active`. If a restart happens instead, see the pageserver crash
-failure mode.
-
-#### Orchestrator Drain Times Out
-
-Orchestrator will still proceed with the restart.
-When the pageserver re-attaches, the scheduling policy is set back to
-`Active`.
-
-#### Orchestrator Fill Times Out
-
-Orchestrator will attempt to cancel the fill operation. If that fails,
-the fill will continue until it quiesces and the node will be left
-in the `Filling` scheduling policy. This hinders the scheduler, but is
-otherwise harmless. A human operator can handle this by setting the scheduling
-policy to `Active`, or we can bake in a fill timeout into the storage controller.
-
-## Optimizations
-
-### Location Warmth
-
-When cutting over to a secondary, the storage controller will wait for it to
-become "warm" (i.e. download enough of the tenants data). This means that some
-reconciliations can take significantly longer than others and hold up precious
-reconciliations units. As an optimization, the drain stage can only cut over
-tenants that are already "warm". Similarly, the fill stage can prioritise the
-"warmest" tenants in the fill.
-
-Given that the number of tenants by the storage controller will be fairly low
-for the foreseable future, the first implementation could simply query the tenants
-for secondary status. This doesn't scale well with increasing tenant counts, so
-eventually we will need new pageserver API endpoints to report the sets of
-"warm" and "cold" nodes.
-
-## Alternatives Considered
-
-### Draining and Filling Purely as Scheduling Constraints
-
-At its core, the storage controller is a big background loop that detects changes
-in the environment and reacts on them. One could express draining and filling
-of nodes purely in terms of constraining the scheduler (as opposed to having
-such background tasks).
-
-While theoretically nice, I think that's harder to implement and more importantly operate and reason about.
-Consider cancellation of a drain/fill operation. We would have to update the scheduler state, create
-an entirely new schedule (intent state) and start work on applying that. It gets trickier if we wish
-to cancel the reconciliation tasks spawned by drain/fill nodes. How would we know which ones belong
-to the conceptual drain/fill? One could add labels to reconciliations, but it gets messy in my opinion.
-
-It would also mean that reconciliations themselves have side effects that persist in the database
-(persist something to the databse when the drain is done), which I'm not conceptually fond of.
-
-## Proof of Concept

-This RFC is accompanied by a POC which implements nearly everything mentioned here
-apart from the optimizations and some of the failure handling:

-# Ancestor Timeline Deletion
-
-Created on: 2024-02-23
-
-Author: John Spray
-
-# Summary
-
-When a tenant creates a new timeline that they will treat as their 'main' history,
-it is awkward to permanently retain an 'old main' timeline as its ancestor. Currently
-this is necessary because it is forbidden to delete a timeline which has descendents.
-
-A new pageserver API is proposed to 'adopt' data from a parent timeline into
-one of its children, such that the link between ancestor and child can be severed,
-leaving the parent in a state where it may then be deleted.
-
-# Motivation
-
-Retaining parent timelines currently has two costs:
-
-- Cognitive load on users, who have to remember which is the "real" main timeline.
-- Storage capacity cost, as the parent timeline will retain layers up to the
-  child's timeline point, even if the child fully covers its keyspace with image
-  layers and will never actually read from the parent.
-
-# Solution
-
-A new pageserver API `PUT /v1/tenant/:tenant_id/timeline/:timeline_id/detach_ancestor`
-will be added. The `timeline_id` in this URL is that of the _child_ timeline that we
-wish to detach from its parent.
-
-On success, this API will leave the following state:
-
-- The detached child timeline will no longer have an ancestor, and will contain all
-  the data needed to service reads without recursing into an ancestor.
-- Any other children of the parent whose timeline points were at a lower LSN than
-  the detached child timeline will be modified to have the child timeline as their
-  new parent.
-- The parent timeline will still exist, but the child will no longer have it as an
-  ancestor. If this was the last timeline that depended on the parent, then the
-  parent will become deletable.
-
-This API's implementation will consist of a series of retryable steps, such that
-on failures/timeout it can safely be called again to reach the target state.
-
-## Example
-
-### Before
-
-The user has "rolled back" their project to LSN X, resulting in a "new main"
-timeline. The parent "old main" timeline still exists, and they would like
-to clean it up.
-
-They have two other timelines A and B. A is from before the rollback point,
-and B is from after the rollback point.
-
-```
-----"old main" timeline-------X-------------------------------------------->
-                |             |                         |
-                |-> child A   |                         |
-                              |-> "new main" timeline   |
-                                                        -> child B
-
-```
-
-### After calling detach ancestor API
-
-The "new main" timeline is no longer dependent on old main, and neither
-is child A, because it had a branch point before X.
-
-The user may now choose to delete child B and "old main" to get to
-a pristine state. Child B is likely to be unwanted since the user
-chose to roll back to X, and it branches from after X. However, we
-don't assume this in the API; it is up to the user to delete it.
-
-```
-|----"old main" timeline---------------------------------------------------->
-                                                         |
-                                                         |
-                                                         |
-                                                         -> child B
-
-|----"new main" timeline--------->
-                 |
-                 |-> child A
-
-
-```
-
-### After removing timelines
-
-We end up with a totally clean state that leaves no trace that a rollback
-ever happened: there is only one root timeline.
-
-```
-| ----"new main" timeline----------->
-                |
-                |-> child A
-
-
-```
-
-## Caveats
-
-Important things for API users to bear in mind:
-
-- this API does not delete the parent timeline: you must still do that explicitly.
-- if there are other child timelines ahead of the branch point of the detached
-  child, the parent won't be deletable: you must either delete or detach those
-  children.
-- do _not_ simply loop over all children and detach them all: this can have an
-  extremely high storage cost. The detach ancestor API is intended for use on a single
-  timeline to make it the new "main".
-- The detach ancestor API should also not be
-  exposed directly to the user as button/API, because they might decide
-  to click it for all the children and thereby generate many copies of the
-  parent's data -- the detach ancestor API should be used as part
-  of a high level "clean up after rollback" feature.
-
-## `detach_ancestor` API implementation
-
-Terms used in the following sections:
-
-- "the child": the timeline whose ID is specified in the detach ancestor API URL, also
-  called "new main" in the example.
-- "the parent": the parent of "the child". Also called "old main" in the example.
-- "the branch point" the ancestor_lsn of "the child"
-
-### Phase 1: write out adopted layers to S3
-
-The child will "adopt" layers from the parent, such that its end state contains
-all the parent's history as well as its own.
-
-For all layers in the parent's layer map whose high LSN is below the branch
-point, issue S3 CopyObject requests to duplicate them into the child timeline's
-prefix. Do not add them to the child's layer map yet.
-
-For delta layers in the parent's layer map which straddle the branch point, read them
-and write out only content up to the branch point into new layer objects.
-
-This is a long running operation if the parent has many layers: it should be
-implemented in a way that resumes rather than restarting from scratch, if the API
-times out and is called again.
-
-As an optimization, if there are no other timelines that will be adopted into
-the child, _and_ the child's image layers already full cover the branch LSN,
-then we may skip adopting layers.
-
-### Phase 2: update the child's index
-
-Having written out all needed layers in phase 1, atomically link them all
-into the child's IndexPart and upload to S3. This may be done while the
-child Timeline is still running.
-
-### Phase 3: modify timelines ancestry
-
-Modify the child's ancestor to None, and upload its IndexPart to persist the change.
-
-For all timelines which have the same parent as the child, and have a branch
-point lower than our branch point, switch their ancestor_timeline to the child,
-and upload their IndexPart to persist the change.
-
-## Alternatives considered
-
-### Generate full image layer on child, rather than adopting parent deltas
-
-This would work for the case of a single child, but would prevent re-targeting
-other timelines that depended on the parent. If we detached many children this
-way, the storage cost would become prohibitive (consider a 1TB database with
-100 child timelines: it would cost 100TiB if they all generated their own image layers).
-
-### Don't rewrite anything: just fake it in the API
-
-We could add a layer of indirection that let a child "pretend" that it had no
-ancestor, when in reality it still had the parent. The pageserver API could
-accept deletion of ancestor timelines, and just update child metadata to make
-them look like they have no ancestor.
-
-This would not achieve the desired reduction in storage cost, and may well be more
-complex to maintain than simply implementing the API described in this RFC.
-
-### Avoid copying objects: enable child index to use parent layers directly
-
-We could teach IndexPart to store a TimelineId for each layer, such that a child
-timeline could reference a parent's layers directly, rather than copying them
-into the child's prefix.
-
-This would impose a cost for the normal case of indices that only target the
-timeline's own layers, add complexity, and break the useful simplifying
-invariant that timelines "own" their own path. If child timelines were
-referencing layers from the parent, we would have to ensure that the parent
-never runs GC/compaction again, which would make the API less flexible (the
-proposal in this RFC enables deletion of the parent but doesn't require it.)
-
-## Performance
-
-### Adopting layers
-
-- CopyObject is a relatively cheap operation, but we may need to issue tens of thousands
-  of such requests: this can take up to tens of seconds and will compete for RemoteStorage
-  semaphore units with other activity on the pageserver.
-- If we are running on storage backend that doesn't implement CopyObject, then
-  this part will be much more expensive as we would stream all layer content
-  through the pageserver. This is no different to issuing a lot
-  of reads to a timeline that does not have a warm local cache: it will move
-  a lot of gigabytes, but that shouldn't break anything.
-- Generating truncated layers for delta that straddle the branch point will
-  require streaming read/write of all the layers in question.
-
-### Updating timeline ancestry
-
-The simplest way to update timeline ancestry will probably be to stop and start
-all the Timeline objects: this is preferable to the complexity of making their
-ancestry mutable at runtime.
-
-There will be a corresponding "stutter" in the availability of the timelines,
-of the order 10-100ms, which is the time taken to upload their IndexPart, and
-restart the Timeline.
-
-# Interaction with other features
-
-## Concurrent timeline creation
-
-If new historic timelines are created using the parent as an ancestor while the
-detach ancestor API is running, they will not be re-parented to the child. This
-doesn't break anything, but it leaves the parent in a state where it might not
-be possible to delete it.
-
-Since timeline creations are an explicit user action, this is not something we need to
-worry about as the storage layer: a user who wants to delete their parent timeline will not create
-new children, and if they do, they can choose to delete those children to
-enable deleting the parent.
-
-For the least surprise to the user, before starting the detach ancestor branch
-operation, the control plane should wait until all branches are created and not
-allow any branches to be created before the branch point on the ancestor branch
-while the operation is ongoing.
-
-## WAL based disaster recovery
-
-WAL based disaster recovery currently supports only restoring of the main
-branch. Enabling WAL based disaster recovery in the future requires that we
-keep a record which timeline generated the WAL and at which LSN was a parent
-detached. Keep a list of timeline ids and the LSN in which they were detached in
-the `index_part.json`. Limit the size of the list to 100 first entries, after
-which the WAL disaster recovery will not be possible.
-
-## Sharded tenants
-
-For sharded tenants, calls to the detach ancestor API will pass through the storage
-controller, which will handle them the same as timeline creations: invoke first
-on shard zero, and then on all the other shards.

-# Timeline Archival
-
-## Summary
-
-This RFC describes a mechanism for pageservers to eliminate local storage + compute work
-for timelines which are not in use, in response to external API calls to "archive" a timeline.
-
-The archived state roughly corresponds to fully offloading a timeline to object storage, such
-that its cost is purely the cost of that object storage.
-
-## Motivation
-
-Archived timelines serve multiple purposes:
-- Act as a 'snapshot' for workloads that would like to retain restorable copies of their
-  database from longer ago than their PITR window.
-- Enable users to create huge numbers of branches (e.g. one per github PR) without having
-  to diligently clean them up later to avoid overloading the pageserver (currently we support
-  up to ~500 branches per tenant).
-
-### Prior art
-
-Most storage and database systems have some form of snapshot, which can be implemented several ways:
-1. full copies of data (e.g. an EBS snapshot to S3)
-2. shallow snapshots which are CoW relative to the original version of the data, e.g. on a typical NFS appliance, or a filesystem like CephFS.
-3. a series of snapshots which are CoW or de-duplicated relative to one another.
-
-Today's Neon branches are approximately like `2.`, although due to implementation details branches
-often end up storing much more data than they really need, as parent branches assume that all data
-at the branch point is needed.  The layers pinned in the parent branch may have a much larger size
-than the physical size of a compressed image layer representing the data at the branch point.
-
-## Requirements
-
-- Enter & exit the archived state in response to external admin API calls
-- API calls to modify the archived state are atomic and durable
-- An archived timeline should eventually (once out of PITR window) use an efficient compressed
-  representation, and avoid retaining arbitrarily large data in its parent branch.
-- Remote object GETs during tenant start may be O(N) with the number of _active_ branches,
-  but must not scale with the number of _archived_ branches.
-- Background I/O for archived branches should only be done a limited number of times to evolve them
-  to a long-term-efficient state (e.g. rewriting to image layers).  There should be no ongoing "housekeeping"
-  overhead for archived branches, including operations related to calculating sizes for billing.
-- The pageserver should put no load on the safekeeper for archived branches.
-- Performance of un-archiving a branch must make good use of S3/disk bandwidth to restore the branch
-  to a performant state in a short time (linear with the branch's logical size)
-
-## Non Goals
-
-- Archived branches are not a literal `fullbackup` postgres snapshot: they are still stored
-  in Neon's internal format.
-- Compute cold starts after activating an archived branch will not have comparable performance to
-  cold starts on an active branch.
-- Archived branches will not use any new/additional compression or de-duplication beyond what
-  is already implemented for image layers (zstd per page).
-- The pageserver will not "auto start" archived branches in response to page_service API requests: they
-  are only activated explicitly via the HTTP API.
-- We will not implement a total offload of archived timelines from safekeepers: their control file (small) will
-  remain on local disk, although existing eviction mechanisms will remove any segments from local disk.
-- We will not expose any prometheus metrics for archived timelines, or make them visible in any
-  detailed HTTP APIs other than the specific API for listing archived timelines.
-- A parent branch may not be archived unless all its children are.
-
-## Impacted Components
-
-pageserver, storage controller
-
-## Terminology
-
-**Archived**: a branch is _archived_ when an HTTP API request to archive it has succeeded: the caller
-may assume that this branch is now very cheap to store, although this may not be physically so until the
-branch proceeds to the offloaded state.
-
-**Active** branches are branches which are available for use by page_service clients, and have a relatively
-high cost due to consuming local storage.
-
-**Offloaded** branches are a subset of _archived_ branches, which have had their local state removed such
-that they now consume minimal runtime resources and have a cost similar to the cost of object storage.
-
-**Activate** (verb): transition from Archived to Active
-
-**Archive** (verb): transition from Active to Archived
-
-**Offload** (verb): transition from Archived to Offloaded
-
-**Offload manifest**: an object stored in S3 that describes timelines which pageservers do not load.
-
-**Warm up** (verb): operation done on an active branch, by downloading its active layers.  Once a branch is
-warmed up, good performance will be available to page_service clients.
-
-## Implementation
-
-### High level flow
-
-We may think of a timeline which is archived and then activated as proceeding through a series of states:
-
-```mermaid
-stateDiagram
-  [*] --> Active(warm)
-  Active(warm) --> Archived
-  Archived --> Offloaded
-  Archived --> Active(warm)
-  Offloaded --> Active(cold)
-  Active(cold) --> Active(warm)
-```
-
-Note that the transition from Archived to Active(warm) is expected to be fairly rare: the most common lifecycles
-of branches will be:
-- Very frequent: Short lived branches: Active -> Deleted
-- Frequent: Long-lived branches: Active -> Archived -> Offloaded -> Deleted
-- Rare: Branches used to restore old state: Active ->Archived -> Offloaded -> Active
-
-These states are _not_ all stored as a single physical state on the timeline, but rather represent the combination
-of:
-- the timeline's lifecycle state: active or archived, stored in the timeline's index
-- its offload state: whether pageserver has chosen to drop local storage of the timeline and write it into the
-  manifest of offloaded timelines.
-- cache state (whether it's warm or cold).
-
-### Storage format changes
-
-There are two storage format changes:
-1. `index_part.json` gets a new attribute `state` that describes whether the timeline is to
-   be considered active or archived.
-2. A new tenant-level _manifest_ object `tenant_manifest-v1.json` describes which timelines a tenant does not need to load
-   at startup (and is available for storing other small, rarely changing tenant-wide attributes in future)
-
-The manifest object will have a format like this:
-```
-{
-  "offload_timelines": [
-    {
-      "timeline_id": ...
-      "last_record_lsn": ...
-      "last_record_lsn_time": ...
-      "pitr_interval": ...
-      "last_gc_lsn": ...  # equal to last_record_lsn if this branch has no history (i.e. a snapshot)
-      "logical_size": ...  # The size at last_record_lsn
-      "physical_size" ...
-      "parent": Option<{
-        "timeline_id"...
-        "lsn"... # Branch point LSN on the parent
-        "requires_data": bool # True if this branch depends on layers in its parent, identify it here
-
-      }>
-    }
-  ]
-}
-```
-
-The information about a timeline in its offload state is intentionally minimal: just enough to decide:
-- Whether it requires [archive optimization](#archive-branch-optimization) by rewriting as a set of image layers: we may infer this
-  by checking if now > last_record_lsn_time - pitr_interval, and pitr_lsn < last_record_lsn.
-- Whether a parent branch should include this offloaded branch in its GC inputs to avoid removing
-  layers that the archived branch depends on
-- Whether requests to delete this `timeline_id` should be executed (i.e. if a deletion request
-  is received for a timeline_id that isn't in the site of live `Timelines` or in the manifest, then
-  we don't need to go to S3 for the deletion.
-- How much archived space to report in consumption metrics
-
-The contents of the manifest's offload list will also be stored as an attribute of `Tenant`, such that the total
-set of timelines may be found by the union of `Tenant::timelines` (non-offloaded timelines) and `Tenant::offloaded`
-(offloaded timelines).
-
-For split-brain protection, the manifest object will be written with a generation suffix, in the same way as
-index_part objects are (see [generation numbers RFC](025-generation-numbers.md)).  This will add some complexity, but
-give us total safety against two pageservers with the same tenant attached fighting over the object.  Existing code
-for finding the latest generation and for cleaning up old generations (in the scrubber) will be generalized to cover
-the manifest file.
-
-### API & Timeline state
-
-Timelines will store a lifecycle state (enum of Active or Archived) in their IndexPart.  This will
-be controlled by a new per-timeline `configure` endpoint.  This is intentionally generic naming, which
-may be used in future to control other per-timeline attributes (e.g. in future we may make PITR interval
-a per-timeline configuration).
-
-`PUT /v1/tenants/{tenant_id}/timelines/{timeline_id}/configure`
-```
-{
-  'state': 'active|archive'
-}
-```
-
-When archiving a timeline, this API will complete as soon as the timeline's state has been set in index_part, and that index has been uploaded.
-
-When activating a timeline, this API will complete as soon as the timeline's state has been set in index_part,
-**and** the `Timeline` object has been instantiated and activated.  This will require reading the timeline's
-index, but not any data: it should be about as fast as a couple of small S3 requests.
-
-The API will be available with identical path via the storage controller: calling this on a sharded tenant
-will simply map the API call to all the shards.
-
-Archived timelines may never have descendent timelines which are active.  This will be enforced at the API level,
-such that activating a timeline requires that all its ancestors are active, and archiving a timeline requires
-that all its descendents are archived.  It is the callers responsibility to walk the hierarchy of timelines
-in the proper order if they would like to archive whole trees of branches.
-
-Because archive timelines will be excluded from the usual timeline listing APIs, a new API specifically
-for archived timelines will be added: this is for use in support/debug:
-
-```
-GET /v1/tenants/{tenant_id}/archived_timelines
-
-{
-  ...same per-timeline content as the tenant manifest...
-}
-
-```
-
-### Tenant attach changes
-
-Currently, during Tenant::spawn we list all the timelines in the S3 bucket, and then for each timeline
-we load their index_part.json.  To avoid the number of GETs scaling linearly with the number of archived
-timelines, we must have a single object that tells us which timelines do not need to be loaded.  The
-number of ListObjects requests while listing timelines will still scale O(N), but this is less problematic
-because each request covers 1000 timelines.
-
-This is **not** literally the same as the set of timelines who have state=archived.  Rather, it is
-the set of timelines which have been offloaded in the background after their state was set to archived.
-
-We may simply skip loading these timelines: there will be no special state of `Timeline`, they just won't
-exist from the perspective of an active `Tenant` apart from in deletion: timeline deletion will need
-to check for offloaded timelines as well as active timelines, to avoid wrongly returning 404 on trying
-to delete an offloaded timeline.
-
-### Warm-up API
-
-`PUT /v1/tenants/{tenant_id}/timelines/{timeline_id}/download?wait_ms=1234`
-
-This API will be similar to the existing `download_remote_layers` API, but smarter:
-- It will not download _all_ remote layers, just the visible set (i.e. layers needed for a read)
-- It will download layers in the visible set until reaching `wait_ms`, then return a struct describing progress
-  of downloads, so that the caller can poll.
-
-The _visible set_ mentioned above will be calculated by the pageserver in the background, by taking the set
-of readable LSNs (i.e. branch points and heads of branches), and walking the layer map to work out which layers
-can possibly be read from these LSNs.  This concept of layer visibility is more generally useful for cache
-eviction and heatmaps, as well as in this specific case of warming up a timeline.
-
-The caller does not have to wait for the warm up API, or call it at all.  But it is strongly advised
-to call it, because otherwise populating local contents for a timeline can take a long time when waiting
-for SQL queries to coincidentally hit all the layers, and during that time query latency remains quite
-volatile.
-
-### Background work
-
-Archived branches are not subject to normal compaction.  Instead, when the compaction loop encounters
-an archived branch, it will consider rewriting the branch to just image layers if the branch has no history
-([archive branch optimization](#archive-branch-optimization)), or offloading the timeline from local disk
-if its state permits that.
-
-Additionally, the tenant compaction task will walk the state of already offloaded timelines to consider
-optimizing their storage, e.g. if a timeline had some history when offloaded, but since then its PITR
-has elapsed and it can now be rewritten to image layers.
-
-#### Archive branch offload
-
-Recall that when we archive a timeline via the HTTP API, this only sets a state: it doesn't do
-any actual work.
-
-This work is done in the background compaction loop.  It makes sense to tag this work on to the compaction
-loop, because it is spiritually aligned: offloading data for archived branches improves storage efficiency.
-
-The condition for offload is simple:
- - a `Timeline` object exists with state `Archived`
- - the timeline does not have any non-offloaded children.
- 
- Regarding the condition that children must be offloaded, this will always be eventually true, because
- we enforce at the API level that children of archived timelines must themselves be archived, and all
- archived timelines will eventually be offloaded.
-
-Offloading a timeline is simple:
-- Read the timeline's attributes that we will store in its offloaded state (especially its logical size)
-- Call `shutdown()` on the timeline and remove it from the `Tenant` (as if we were about to delete it)
-- Erase all the timeline's content from local storage (`remove_dir_all` on its path)
-- Write the tenant manifest to S3 to prevent this timeline being loaded on next start.
-
-#### Archive branch optimization (flattening)
-
-When we offloaded a branch, it might have had some history that prevented rewriting it to a single
-point in time set of image layers.  For example, a branch might have several days of writes and a 7
-day PITR: when we archive it, it still has those days of history.
-
-Once the PITR has expired, we have an opportunity to reduce the physical footprint of the branch by:
-- Writing compressed image layers within the archived branch, as these are more efficient as a way of storing
-  a point in time compared with delta layers
-- Updating the branch's offload metadata to indicate that this branch no longer depends on its ancestor
-  for data, i.e. the ancestor is free to GC layers files at+below the branch point
-
-Fully compacting an archived branch into image layers at a single LSN may be thought of as *flattening* the
-branch, such that it is now a one-dimensional keyspace rather than a two-dimensional key/lsn space. It becomes
-a true snapshot at that LSN.
-
-It is not always more efficient to flatten a branch than to keep some extra history on the parent: this
-is described in more detail in [optimizations](#delaying-storage-optimization-if-retaining-parent-layers-is-cheaper)
-
-Archive branch optimization should be done _before_ background offloads during compaction, because there may
-be timelines which are ready to be offloaded but also would benefit from the optimization step before
-being offloaded.  For example, a branch which has already fallen out of PITR window and has no history
-of its own may be immediately re-written as a series of image layers before being offloaded.
-
-### Consumption metrics
-
-Archived timelines and offloaded timelines will be excluded from the synthetic size calculation, in anticipating
-that billing structures based on consumption metrics are highly likely to apply different $/GB rates to archived
-vs. ordinary content.
-
-Archived and offloaded timelines' logical size will be reported under the existing `timeline_logical_size`
-variant of `MetricsKey`: receivers are then free to bill on this metric as they please.
-
-### Secondary locations
-
-Archived timelines (including offloaded timelines) will be excluded from heatmaps, and thereby
-when a timeline is archived, after the next cycle of heatmap upload & secondary download, its contents
-will be dropped from secondary locations.
-
-### Sharding
-
-Archiving or activating a timeline will be done symmetrically across all shards in a tenant, in
-the same way that timeline creation and deletion is done.  There are no special rules about ordering:
-the storage controller may dispatch concurrent calls to all shards when archiving or activating a timeline.
-
-Since consumption metrics are only transmitted from shard zero, the state of archival on this shard
-will be authoritative for consumption metrics.
-
-## Error cases
-
-### Errors in sharded tenants
-
-If one shard in a tenant fails an operation but others succeed, the tenant may end up in a mixed
-state, where a timeline is archived on some shards but not on others.  
-
-We will not bother implementing a rollback mechanism for this: errors in archiving/activating a timeline
-are either transient (e.g. S3 unavailable, shutting down), or the fault of the caller (NotFound, BadRequest).
-In the transient case callers are expected to retry until success, or to make appropriate API calls to clear
-up their mistake.  We rely on this good behavior of callers to eventually get timelines into a consistent
-state across all shards.  If callers do leave a timeline in an inconsistent state across shards, this doesn't
-break anything, it's just "weird".
-
-This is similar to the status quo for timeline creation and deletion: callers are expected to retry
-these operations until they succeed.
-
-### Archiving/activating
-
-Archiving/activating a timeline can fail in a limited number of ways:
-1. I/O error storing/reading the timeline's updated index
-    - These errors are always retryable: a fundamental design assumption of the pageserver is that remote
-      storage errors are always transient. 
-2. NotFound if the timeline doesn't exist
-    - Callers of the API are expected to avoid calling deletion and archival APIs concurrently.
-    - The storage controller has runtime locking to prevent races such as deleting a timeline while
-      archiving it.
-3. BadRequest if the rules around ancestors/descendents of archived timelines would be violated
-    - Callers are expected to do their own checks to avoid hitting this case.  If they make
-      a mistake and encounter this error, they should give up.
-
-### Offloading
-
-Offloading can only fail if remote storage is unavailable, which would prevent us from writing the
-tenant manifest.  In such error cases, we give up in the expectation that offloading will be tried 
-again at the next iteration of the compaction loop.
-
-### Archive branch optimization
-
-Optimization is a special form of compaction, so can encounter all the same errors as regular compaction
-can: it should return Result<(), CompactionError>, and as with compaction it will be retried on
-the next iteration of the compaction loop.
-
-## Optimizations
-
-### Delaying storage optimization if retaining parent layers is cheaper
-
-Optimizing archived branches to image layers and thereby enabling parent branch GC to progress
-is a safe default: archived branches cannot over-fill a pageserver's local disk, and once they
-are offloaded to S3 they're totally safe, inert things.
-
-However, in some cases it can be advantageous to retain extra history on their parent branch rather
-than flattening the archived branch.  For example, if a 1TB parent branch is rather slow-changing (1GB
-of data per day), and archive branches are being created nightly, then writing out full 1TB image layers
-for each nightly branch is inefficient compared with just keeping more history on the main branch.
-
-Getting this right requires consideration of:
-- Compaction: if keeping more history on the main branch is going to prompt the main branch's compaction to
-  write out extra image layers, then it might make more sense to just write out the image layers on
-  the archived branch.
-- Metadata bloat: keeping extra history on a parent branch doesn't just cost GB of storage, it makes
-  the layer map (and index_part) bigger.  There are practical limits beyond which writing an indefinitely
-  large layer map can cause problems elsewhere.
-
-This optimization can probably be implemented quite cheaply with some basic heuristics like:
-- don't bother doing optimization on an archive branch if the LSN distance between
-  its branch point and the end of the PITR window is <5% of the logical size of the archive branch.
-- ...but, Don't keep more history on the main branch than double the PITR
-
-### Creating a timeline in archived state (a snapshot)
-
-Sometimes, one might want to create a branch with no history, which will not be written to
-before it is archived.  This is a snapshot, although we do not require a special snapshot API,
-since a snapshot can be represented as a timeline with no history.
-
-This can be accomplished by simply creating a timeline and then immediately archiving it, but
-that is somewhat wasteful: this timeline it will spin up various tasks and open a connection to the storage
-broker to try and ingest WAL, before being shutdown in the subsequent archival call.  To explicitly
-support this common special case, we may add a parameter to the timeline creation API which
-creates a timeline directly into the archived state.
-
-Such a timeline creation will do exactly two I/Os at creation time:
-- write the index_part object to record the timeline's existence
-- when the timeline is offloaded in the next iteration of the compaction loop (~20s later),
-  write the tenant manifest.
-
-Later, when the timeline falls off the end of the PITR interval, the usual offload logic will wake
-up the 'snapshot' branch and write out image layers.
-
-## Future Work
-
-### Enabling `fullbackup` dumps from archive branches
-
-It would be useful to be able to export an archive branch to another system, or for use in a local
-postgres database.
-
-This could be implemented as a general capability for all branches, in which case it would "just work"
-for archive branches by activating them.  However, downloading all the layers in a branch just to generate
-a fullbackup is a bit inefficient: we could implement a special case for flattened archived branches
-which streams image layers from S3 and outputs the fullbackup stream without writing the layers out to disk.
-
-Implementing `fullbackup` is a bit more complicated than this because of sharding, but solving that problem
-is unrelated to the topic of archived branches (it probably involves having each shard write out a fullbackup 
-stream to S3 in an intermediate format and, then having one node stitch them together).
-
-### Tagging layers from archived branches
-
-When we know a layer is an image layer written for an archived branch that has fallen off the PITR window,
-we may add tags to the S3 objects to enable writing lifecycle policies that transition such layers to even
-cheaper storage.
-
-This could be done for all archived layers, or it could be driven by the archival API, to give the pageserver
-external hints on which branches are likely to be reactivated, and which branches are good candidates for
-tagging for low performance storage.
-
-Tagging+lifecycles is just one mechanism: one might also directly use S3 storage classes.  Other clouds' object
-stores have similar mechanisms.
-
-### Storing sequences of archive branches as deltas
-
-When archived branches are used as scheduled snapshots, we could store them even more efficiently
-by encoding them as deltas relative to each other (i.e. for nightly snapshots, when we do the
-storage optimization for Tuesday's snapshot, we would read Monday's snapshot and store only the modified
-pages). This is the kind of encoding that many backup storage systems use.
-
-The utility of this depends a lot on the churn rate of the data, and the cost of doing the delta encoding
-vs. just writing out a simple stream of the entire database.  For smaller databases, writing out a full
-copy is pretty trivial (e.g. writing a compressed copy of a 10GiB database to S3 can take under 10 seconds,
-so the complexity tradeoff of diff-encoding it is dubious).
-
-One does not necessarily have to read-back the previous snapshot in order to encoded the next one: if the
-pageserver knows about the schedule, it can intentionally retain extra history on the main branch so that
-we can say: "A branch exists from Monday night.  I have Monday night's data still active in the main branch,
-so now I can read at the Monday LSN and the Tuesday LSN, calculate the delta, and store it as Tuesday's
-delta snapshot".
-
-Clearly this all requires careful housekeeping to retain the relationship between branches that depend on
-each other: perhaps this would be done by making the archive branches have child/parent relationships with
-each other, or perhaps we would permit them to remain children of their original parent, but additionally
-have a relationship with the snapshot they're encoded relative to.
-
-Activating a branch that is diff-encoded may require activating several earlier branches too, so figuring
-out how frequently to write a full copy is important.  This is essentially a zoomed-out version of what
-we do with delta layers and image layers within a timeline, except each "layer" is a whole timeline.
-
-
-## FAQ/Alternatives
-
-### Store all timelines in the tenant manifest
-
-Rather than special-casing offloaded timelines in the offload manifest, we could store a total
-manifest of all timelines, eliminating the need for the pageserver to list timelines in S3 on
-startup.
-
-That would be a more invasive change (require hooking in to timeline creation), and would
-generate much more I/O to this manifest for tenants that had many branches _and_ frequent
-create/delete cycles for short lived branches.  Restricting the manifest to offloaded timelines
-means that we only have to cope with the rate at which long-lived timelines are archived, rather
-than the rate at which sort lived timelines are created & destroyed.
-
-### Automatically archiving/activating timelines without external API calls
-
-We could implement TTL driven offload of timelines, waking them up when a page request
-arrives.
-
-This has downsides:
-- Opacity: if we do TTL-driven offload inside the pageserver, then the end user doesn't
-  know which of their branches are in this state, and might get a surprise when they try
-  to use such a branch.
-- Price fluctuation: if the archival of a branch is used in end user pricing, then users
-  prefer clarity & consistency.  Ideally a branch's storage should cost the same from the moment it
-  is created, rather than having a usage-dependency storage price.
-- Complexity: enabling the page service to call up into the Tenant to activate a timeline
-  would be awkward, compared with an external entry point.
-
-### Make offloaded a state of Timeline
-
-To reduce the operator-facing complexity of having some timelines APIs that only return
-non-offloaded timelines, we could build the offloaded state into the Timeline type.
-
-`timeline.rs` is already one of the most egregiously long source files in the tree, so
-this is rejected on the basis that we need to avoid making that complexity worse.
