+### Async cancellation safety
 
-We use async to wait for incoming data on network connections, and to

-received from the network, the task calls the blocking functions in
-the Repository to process the WAL.
+In async Rust, futures can be "cancelled" at any await point, by
+dropping the Future. For example, `tokio::select!` returns as soon as
+one of the Futures returns, and drops the others. `tokio::timeout!` is
+another example. In the Rust ecosystem, some functions are
+cancellation-safe, meaning they can be safely dropped without
+side-effects, while others are not. See documentation of
+`tokio::select!` for examples.
 
-The core storage code in `layered_repository/` is synchronous, with
-blocking locks and I/O calls. The current model is that we consider
-disk I/Os to be short enough that we perform them while running in a
-Tokio task. If that becomes a problem, we should use `spawn_blocking`
-before entering the synchronous parts of the code, or switch to using
-tokio I/O functions.
+In the pageserver and safekeeper, async code is *not*
+cancellation-safe by default. Unless otherwise marked, any async
+function that you call cannot be assumed to be async
+cancellation-safe, and must be polled to completion.
 
-Be very careful when mixing sync and async code!
+The downside of non-cancellation safe code is that you have to be very
+careful when using `tokio::select!`, `tokio::timeout!`, and other such
+functions that can cause a Future to be dropped. They can only be used
+with functions that are explicitly documented to be cancellation-safe,
+or you need to spawn a separate task to shield from the cancellation.
+
+At the entry points to the code, we also take care to poll futures to
+completion, or shield the rest of the code from surprise cancellations
+by spawning a separate task. The code that handles incoming HTTP
+requests, for example, spawns a separate task for each request,
+because Hyper will drop the request-handling Future if the HTTP
+connection is lost.
+
+
+#### How to cancel, then?
+
+If our code is not cancellation-safe, how do you cancel long-running
+tasks? Use CancellationTokens.
+
+TODO: More details on that. And we have an ongoing discussion on what
+to do if cancellations might come from multiple sources.
+
+#### Exceptions
+Some library functions are cancellation-safe, and are explicitly marked
+as such. For example, `utils::seqwait`.
+
+#### Rationale
+
+The alternative would be to make all async code cancellation-safe,
+unless otherwise marked. That way, you could use `tokio::select!` more
+liberally. The reasons we didn't choose that are explained in this
+section.
+
+Writing code in a cancellation-safe manner is tedious, as you need to
+scrutinize every `.await` and ensure that if the `.await` call never
+returns, the system is in a safe, consistent state. In some ways, you
+need to do that with `?` and early `returns`, too, but `.await`s are
+easier to miss. It is also easier to perform cleanup tasks when a
+function returns an `Err` than when an `.await` simply never
+returns. You can use `scopeguard` and Drop guards to perform cleanup
+tasks, but it is more tedious. An `.await` that never returns is more
+similar to a panic.
+
+Note that even if you only use building blocks that themselves are
+cancellation-safe, it doesn't mean that the code as whole is
+cancellation-safe. For example, consider the following code:
+
+```
+while let Some(i) = work_inbox.recv().await {
+	if let Err(_) = results_outbox.send(i).await {
+		println!("receiver dropped");
+		return;
+		}
+	}
+}
+```
+
+It reads messages from one channel, sends them to another channel. If
+this code is cancelled at the `results_outbox.send(i).await`, the
+message read from the receiver is lost. That may or may not be OK,
+depending on the context.
+
+Another reason to not require cancellation-safety is historical: we
+already had a lot of async code that was not scrutinized for
+cancellation-safety when this issue was raised. Scrutinizing all
+existing code is no fun.

+# Deleting pageserver part of tenants data from s3
+
+Created on 08.03.23
+
+## Motivation
+
+Currently we dont delete pageserver part of the data from s3 when project is deleted. (The same is true for safekeepers, but this outside of the scope of this RFC).
+
+This RFC aims to spin a discussion to come to a robust deletion solution that wont put us in into a corner for features like postponed deletion (when we keep data for user to be able to restore a project if it was deleted by accident)
+
+## Summary
+
+TLDR; There are two options, one based on control plane issuing actual delete requests to s3 and the other one that keeps s3 stuff bound to pageserver. Each one has its pros and cons.
+
+The decision is to stick with pageserver centric approach. For motivation see [Decision](#decision).
+
+## Components
+
+pageserver, control-plane
+
+## Requirements
+
+Deletion should successfully finish (eventually) without leaving dangling files in presense of:
+
+- component restarts
+- component outage
+- pageserver loss
+
+## Proposed implementation
+
+Before the options are discussed, note that deletion can be quite long process. For deletion from s3 the obvious choice is [DeleteObjects](https://docs.aws.amazon.com/AmazonS3/latest/API/API_DeleteObjects.html) API call. It allows to batch deletion of up to 1k objects in one API call. So deletion operation linearly depends on number of layer files.
+
+Another design limitation is that there is no cheap `mv` operation available for s3. `mv` from `aws s3 mv` uses `copy(src, dst) + delete(src)`. So `mv`-like operation is not feasible as a building block because it actually amplifies the problem with both duration and resulting cost of the operation.
+
+The case when there are multiple pageservers handling the same tenants is largely out of scope of the RFC. We still consider case with migration from one PS to another, but do not consider case when tenant exists on multiple pageservers for extended period of time. The case with multiple pageservers can be reduced to case with one pageservers by calling detach on all pageservers except the last one, for it actual delete needs to be called.
+
+For simplicity lets look into deleting tenants. Differences in deletion process between tenants and timelines are mentioned in paragraph ["Differences between tenants and timelines"](#differences-between-tenants-and-timelines)
+
+### 1. Pageserver owns deletion machinery
+
+#### The sequence
+
+TLDR; With this approach control plane needs to call delete on a tenant and poll for progress. As much as possible is handled on pageserver. Lets see the sequence.
+
+Happy path:
+
+```mermaid
+sequenceDiagram
+    autonumber
+    participant CP as Control Plane
+    participant PS as Pageserver
+    participant S3
+
+    CP->>PS: Delete tenant
+    PS->>S3: Create deleted mark file at <br> /tenant/meta/deleted
+    PS->>PS: Create deleted mark file locally
+    PS->>CP: Accepted
+    PS->>PS: delete local files other than deleted mark
+    loop Delete layers for each timeline
+        PS->>S3: delete(..)
+        CP->>PS: Finished?
+        PS->>CP: False
+    end
+    PS->>S3: Delete mark file
+    PS->>PS: Delete local mark file
+
+    loop Poll for status
+        CP->>PS: Finished?
+        PS->>CP: True or False
+    end
+```
+
+Why two mark files?
+Remote one is needed for cases when pageserver is lost during deletion so other pageserver can learn the deletion from s3 during attach.
+
+Why local mark file is needed?
+
+If we dont have one, we have two choices, delete local data before deleting the remote part or do that after.
+
+If we delete local data before remote then during restart pageserver wont pick up remote tenant at all because nothing is available locally (pageserver looks for remote conuterparts of locally available tenants).
+
+If we delete local data after remote then at the end of the sequence when remote mark file is deleted if pageserver restart happens then the state is the same to situation when pageserver just missing data on remote without knowing the fact that this data is intended to be deleted. In this case the current behavior is upload everything local-only to remote.
+
+Thus we need local record of tenant being deleted as well.
+
+##### Handle pageserver crashes
+
+Lets explore sequences with various crash points.
+
+Pageserver crashes before `deleted` mark file is persisted in s3:
+
+```mermaid
+sequenceDiagram
+    autonumber
+    participant CP as Control Plane
+    participant PS as Pageserver
+    participant S3

+    CP->>PS: Retry delete request
+
+    PS->>S3: Create deleted mark file at <br> /tenant/meta/deleted
+    PS->>PS: Create deleted mark file locally
+
+    PS->>CP: Accepted
+
+    PS->>PS: delete local files other than deleted mark
+
+    loop Delete layers for each timeline
+        PS->>S3: delete(..)
+        CP->>PS: Finished?

+    PS->>S3: Delete mark file
+    PS->>PS: Delete local mark file
+
+    CP->>PS: Finished?
+    PS->>CP: True
+```
+
+Pageserver crashed when deleted mark was about to be persisted in s3, before Control Plane gets a response:

+    PS->>S3: Delete mark file

+
+    CP->>PS: Finished?
+    PS->>CP: True
+```
+
+Similar sequence applies when both local and remote marks were persisted but Control Plane still didnt receive a response.
+
+If pageserver crashes after both mark files were deleted then it will reply to control plane status poll request with 404 which should be treated by control plane as success.
+
+The same applies if pageserver crashes in the end, when remote mark is deleted but before local one gets deleted. In this case on restart pageserver moves forward with deletion of local mark and Control Plane will receive 404.
+
+##### Differences between tenants and timelines
+
+For timeline the sequence is the same with the following differences:
+
+- remote delete mark file can be replaced with a boolean "deleted" flag in index_part.json
+- local deletion mark is not needed, because whole tenant is kept locally so situation described in motivation for local mark is impossible
+
+##### Handle pageserver loss
+
+If pageseserver is lost then the deleted tenant should be attached to different pageserver and delete request needs to be retried against new pageserver. Then attach logic is shared with one described for pageserver restarts (local deletion mark wont be available so needs to be created).
+
+##### Restrictions for tenant that is in progress of being deleted
+
+I propose to add another state to tenant/timeline - PendingDelete. This state shouldnt allow executing any operations aside from polling the deletion status.
+
+#### Summary
+
+Pros:
+
+- Storage is not dependent on control plane. Storage can be restarted even if control plane is not working.
+- Allows for easier dogfooding, console can use Neon backed database as primary operational data store. If storage depends on control plane and control plane depends on storage we're stuck.
+- No need to share inner s3 workings with control plane. Pageserver presents api contract and S3 paths are not part of this contract.
+- No need to pass list of alive timelines to attach call. This will be solved by pageserver observing deleted flag. See
+
+Cons:
+
+- Logic is a tricky, needs good testing
+- Anything else?
+
+### 2. Control plane owns deletion machinery
+
+In this case the only action performed on pageserver is removal of local files.
+
+Everything else is done by control plane. The steps are as follows:
+
+1. Control plane marks tenant as "delete pending" in its database
+2. It lists the s3 for all the files and repeatedly calls delete until nothing is left behind
+3. When no files are left marks deletion as completed
+
+In case of restart it selects all tenants marked as "delete pending" and continues the deletion.
+
+For tenants it is simple. For timelines there are caveats.
+
+Assume that the same workflow is used for timelines.
+
+If a tenant gets relocated during timeline deletion the attach call with its current logic will pick up deleted timeline in its half deleted state.
+
+Available options:
+
+- require list of alive timelines to be passed to attach call
+- use the same schema with flag in index_part.json (again part of the caveats around pageserver restart applies). In this case nothing stops pageserver from implementing deletion inside if we already have these deletion marks.
+
+With first option the following problem becomes apparent:
+
+Who is the source of truth regarding timeline liveness?
+
+Imagine:
+PS1 fails.
+PS2 gets assigned the tenant.
+New branch gets created
+PS1 starts up (is it possible or we just recycle it?)
+PS1 is unaware of the new branch. It can either fall back to s3 ls, or ask control plane.
+
+So here comes the dependency of storage on control plane. During restart storage needs to know which timelines are valid for operation. If there is nothing on s3 that can answer that question storage neeeds to ask control plane.
+
+### Summary
+
+Cons:
+
+- Potential thundering herd-like problem during storage restart (requests to control plane)
+- Potential increase in storage startup time (additional request to control plane)
+- Storage startup starts to depend on console
+- Erroneous attach call can attach tenant in half deleted state
+
+Pros:
+
+- Easier to reason about if you dont have to account for pageserver restarts
+
+### Extra notes
+
+There was a concern that having deletion code in pageserver is a littlebit scary, but we need to have this code somewhere. So to me it is equally scary to have that in whatever place it ends up at.
+
+Delayed deletion can be done with both approaches. As discussed with Anna (@stepashka) this is only relevant for tenants (projects) not for timelines. For first approach detach can be called immediately and deletion can be done later with attach + delete. With second approach control plane needs to start the deletion whenever necessary.
+
+## Decision
+
+After discussion in comments I see that we settled on two options (though a bit different from ones described in rfc). First one is the same - pageserver owns as much as possible. The second option is that pageserver owns markers thing, but actual deletion happens in control plane by repeatedly calling ls + delete.
+
+To my mind the only benefit of the latter approach is possible code reuse between safekeepers and pageservers. Otherwise poking around integrating s3 library into control plane, configuring shared knowledge abouth paths in s3 - are the downsides. Another downside of relying on control plane is the testing process. Control plane resides in different repository so it is quite hard to test pageserver related changes there. e2e test suite there doesnt support shutting down pageservers, which are separate docker containers there instead of just processes.
+
+With pageserver owning everything we still give the retry logic to control plane but its easier to duplicate if needed compared to sharing inner s3 workings. We will have needed tests for retry logic in neon repo.
+
+So the decision is to proceed with pageserver centric approach.

+# The state of pageserver tenant relocation
+
+Created on 17.03.23
+
+## Motivation
+
+There were previous write ups on the subject. The design of tenant relocation was planned at the time when we had quite different landscape. I e there was no on-demand download/eviction. They were on the horizon but we still planned for cases when they were not available. Some other things have changed. Now safekeepers offload wal to s3 so we're not risking overflowing their disks. Having all of the above, it makes sense to recap and take a look at the options we have now, which adjustments we'd like to make to original process, etc.
+
+Related (in chronological order):
+
+- Tracking issue with initial discussion: [#886](https://github.com/neondatabase/neon/issues/886)
+- [015. Storage Messaging](015-storage-messaging.md)
+- [020. Pageserver S3 Coordination](020-pageserver-s3-coordination.md)
+
+## Summary
+
+The RFC consists of a walkthrough of prior art on tenant relocation and corresponding problems. It describes 3 approaches.
+
+1. Simplistic approach that uses ignore and is the fastest to implement. The main downside is a requirement of short downtime.
+2. More complicated approach that avoids even short downtime.
+3. Even more complicated approach that will allow multiple pageservers to operate concurrently on the same tenant possibly allowing for HA cluster topologies and horizontal scaling of reads (i e compute talks to multiple pageservers).
+
+The order in which solutions are described is a bit different. We start from 2, then move to possible compromises (aka simplistic approach) and then move to discussing directions for solving HA/Pageserver replica case with 3.
+
+## Components
+
+pageserver, control-plane, safekeepers (a bit)
+
+## Requirements
+
+Relocation procedure should move tenant from one pageserver to another without downtime introduced by storage side. For now restarting compute for applying new configuration is fine.
+
+- component restarts
+- component outage
+- pageserver loss
+
+## The original proposed implementation
+
+The starting point is this sequence:
+
+```mermaid
+sequenceDiagram
+    autonumber
+    participant CP as Control Plane
+    participant PS1 as Pageserver 1
+    participant PS2 as Pageserver 2
+    participant S3
+
+    CP->>PS2: Attach tenant X
+    PS2->>S3: Fetch timelines, indexes for them
+    PS2->>CP: Accepted
+    CP->>CP: Change pageserver id in project
+    CP->>PS1: Detach
+```
+
+Which problems do we have with naive approach?
+
+### Concurrent GC and Compaction
+
+The problem is that they can run on both, PS1 and PS2. Consider this example from [Pageserver S3 Coordination RFC](020-pageserver-s3-coordination.md)
+
+```mermaid
+sequenceDiagram
+    autonumber
+    participant PS1
+    participant S3
+    participant PS2
+
+    PS1->>S3: Uploads L1, L2 <br/> Index contains L1 L2
+    PS2->>S3: Attach called, sees L1, L2
+    PS1->>S3: Compaction comes <br/> Removes L1, adds L3
+    note over S3: Index now L2, L3
+    PS2->>S3: Uploads new layer L4 <br/> (added to previous view of the index)
+    note over S3: Index now L1, L2, L4
+```
+
+At this point it is not possible to restore the state from index, it contains L2 which
+is no longer available in s3 and doesnt contain L3 added by compaction by the
+first pageserver. So if any of the pageservers restart, initial sync will fail
+(or in on-demand world it will fail a bit later during page request from
+missing layer)
+
+The problem lies in shared index_part.json. Having intersecting layers from append only edits is expected to work, though this is an uncharted territory without tests.
+
+#### Options
+
+There are several options on how to restrict concurrent access to index file.
+
+First and the simplest one is external orchestration. Control plane which runs migration can use special api call on pageserver to stop background processes (gc, compaction), and even possibly all uploads.
+
+So the sequence becomes:
+
+```mermaid
+sequenceDiagram
+    autonumber
+    participant CP as Control Plane
+    participant PS1 as Pageserver 1
+    participant PS2 as Pageserver 2
+    participant S3
+
+    CP->>PS1: Pause background jobs, pause uploading new layers.
+    CP->>PS2: Attach tenant X.
+    PS2->>S3: Fetch timelines, index, start background operations
+    PS2->>CP: Accepted
+    CP->>CP: Monitor PS2 last record lsn, ensure OK lag
+    CP->>CP: Change pageserver id in project
+    CP->>PS1: Detach
+```
+
+The downside of this sequence is the potential rollback process. What if something goes wrong on new pageserver? Can we safely roll back to source pageserver?
+
+There are two questions:
+
+#### How can we detect that something went wrong?
+
+We can run usual availability check (consists of compute startup and an update of one row).
+Note that we cant run separate compute for that before touching compute that client runs actual workload on, because we cant have two simultaneous computes running in read-write mode on the same timeline (enforced by safekeepers consensus algorithm). So we can either run some readonly check first (basebackup) and then change pageserver id and run availability check. If it failed we can roll it back to the old one.
+
+#### What can go wrong? And how we can safely roll-back?
+
+In the sequence above during attach we start background processes/uploads. They change state in remote storage so it is possible that after rollback remote state will be different from one that was observed by source pageserver. So if target pageserver goes wild then source pageserver may fail to start with changed remote state.
+
+Proposed option would be to implement a barrier (read-only) mode when pageserver does not update remote state.
+
+So the sequence for happy path becomes this one:
+
+```mermaid
+sequenceDiagram
+    autonumber
+    participant CP as Control Plane
+    participant PS1 as Pageserver 1
+    participant PS2 as Pageserver 2
+    participant S3
+
+    CP->>PS1: Pause background jobs, pause uploading new layers.
+    CP->>PS2: Attach tenant X in remote readonly mode.
+    PS2->>S3: Fetch timelines, index
+    PS2->>CP: Accepted
+    CP->>CP: Monitor PS2 last record lsn, ensure OK lag
+    CP->>CP: Change pageserver id in project
+    CP->>CP: Run successful availability check
+    CP->>PS2: Start uploads, background tasks
+    CP->>PS1: Detach
+```
+
+With this sequence we restrict any changes to remote storage to one pageserver. So there is no concurrent access at all, not only for index_part.json, but for everything else too. This approach makes it possible to roll back after failure on new pageserver.
+
+The sequence with roll back process:
+
+```mermaid
+sequenceDiagram
+    autonumber
+    participant CP as Control Plane
+    participant PS1 as Pageserver 1
+    participant PS2 as Pageserver 2
+    participant S3
+
+    CP->>PS1: Pause background jobs, pause uploading new layers.
+    CP->>PS2: Attach tenant X in remote readonly mode.
+    PS2->>S3: Fetch timelines, index
+    PS2->>CP: Accepted
+    CP->>CP: Monitor PS2 last record lsn, ensure OK lag
+    CP->>CP: Change pageserver id in project
+    CP->>CP: Availability check Failed
+    CP->>CP: Change pageserver id back
+    CP->>PS1: Resume remote operations
+    CP->>PS2: Ignore (instead of detach for investigation purposes)
+```
+
+## Concurrent branch creation
+
+Another problem is a possibility of concurrent branch creation calls.
+
+I e during migration create_branch can be called on old pageserver and newly created branch wont be seen on new pageserver. Prior art includes prototyping an approach of trying to mirror such branches, but currently it lost its importance, because now attach is fast because we dont need to download all data, and additionally to the best of my knowledge of control plane internals (cc @ololobus to confirm) operations on one project are executed sequentially, so it is not possible to have such case. So branch create operation will be executed only when relocation is completed. As a safety measure we can forbid branch creation for tenants that are in readonly remote state.
+
+## Simplistic approach
+
+The difference of simplistic approach from one described above is that it calls ignore on source tenant first and then calls attach on target pageserver. Approach above does it in opposite order thus opening a possibility for race conditions we strive to avoid.
+
+The approach largely follows this guide: <https://github.com/neondatabase/cloud/wiki/Cloud:-Ad-hoc-tenant-relocation>
+
+The happy path sequence:
+
+```mermaid
+sequenceDiagram
+    autonumber
+    participant CP as Control Plane
+    participant PS1 as Pageserver 1
+    participant PS2 as Pageserver 2
+    participant SK as Safekeeper
+    participant S3
+
+    CP->>CP: Enable maintenance mode
+    CP->>PS1: Ignore
+    CP->>PS2: Attach
+    PS2->>CP: Accepted
+    loop Delete layers for each timeline
+        CP->>PS2: Get last record lsn
+        CP->>SK: Get commit lsn
+        CP->>CP: OK? Timed out?
+    end
+    CP->>CP: Change pageserver id in project
+    CP->>CP: Run successful availability check
+    CP->>CP: Disable maintenance mode
+    CP->>PS1: Detach ignored
+```
+
+The sequence contains exactly the same rollback problems as in previous approach described above. They can be resolved the same way.
+
+Most probably we'd like to move forward without this safety measure and implement it on top of this approach to make progress towards the downtime-less one.
+
+## Lease based approach
+
+In order to allow for concurrent operation on the same data on remote storage for multiple pageservers we need to go further than external orchestration.
+
+NOTE: [020. Pageserver S3 Coordination](020-pageserver-s3-coordination.md) discusses one more approach that relies on duplication of index_part.json for each pageserver operating on the timeline. This approach still requires external coordination which makes certain things easier but requires additional bookkeeping to account for multiple index_part.json files. Discussion/comparison with proposed lease based approach
+
+The problems are outlined in [020. Pageserver S3 Coordination](020-pageserver-s3-coordination.md) and suggested solution includes [Coordination based approach](020-pageserver-s3-coordination.md#coordination-based-approach). This way it will allow to do basic leader election for pageservers so they can decide which node will be responsible for running GC and compaction. The process is based on extensive communication via storage broker and consists of a lease that is taken by one of the pageservers that extends it to continue serving a leader role.
+
+There are two options for ingesting new data into pageserver in follower role. One option is to avoid WAL ingestion at all and rely on notifications from leader to discover new layers on s3. Main downside of this approach is that follower will always lag behind the primary node because it wont have the last layer until it is uploaded to remote storage. In case of a primary failure follower will be required to reingest last segment (up to 256Mb of WAL currently) which slows down recovery. Additionally if compute is connected to follower pageserver it will observe latest data with a delay. Queries from compute will likely experience bigger delays when recent lsn is required.
+
+The second option is to consume WAL stream on both pageservers. In this case the only problem is non deterministic layer generation. Additional bookkeeping will be required to deduplicate layers from primary with local ones. Some process needs to somehow merge them to remove duplicated data. Additionally we need to have good testing coverage to ensure that our implementation of `get_page@lsn` properly handles intersecting layers.
+
+There is another tradeoff. Approaches may be different in amount of traffic between system components. With first approach there can be increased traffic between follower and remote storage. But only in case follower has some activity that actually requests pages (!). With other approach traffic increase will be permanent and will be caused by two WAL streams instead of one.
+
+## Summary
+
+Proposed implementation strategy:
+
+Go with the simplest approach for now. Then work on tech debt, increase test coverage. Then gradually move forward to second approach by implementing safety measures first, finishing with switch of order between ignore and attach operation.
+
+And only then go to lease based approach to solve HA/Pageserver replica use cases.
