-# Error handling and logging
-
-## Logging errors
-
-The principle is that errors are logged when they are handled. If you
-just propagate an error to the caller in a function, you don't need to
-log it; the caller will. But if you consume an error in a function,
-you *must* log it (if it needs to be logged at all).
-
-For example:
-
-```rust
-fn read_motd_file() -> std::io::Result<String> {
-    let mut f = File::open("/etc/motd")?;
-    let mut result = String::new();
-    f.read_to_string(&mut result)?;
-    result
-}
-```
-
-Opening or reading the file could fail, but there is no need to log
-the error here. The function merely propagates the error to the
-caller, and it is up to the caller to log the error or propagate it
-further, if the failure is not expected. But if, for example, it is
-normal that the "/etc/motd" file doesn't exist, the caller can choose
-to silently ignore the error, or log it as an INFO or DEBUG level
-message:
-
-```rust
-fn get_message_of_the_day() -> String {
-    // Get the motd from /etc/motd, or return the default proverb
-    match read_motd_file() {
-        Ok(motd) => motd,
-        Err(err)  => {
-            // It's normal that /etc/motd doesn't exist, but if we fail to
-            // read it for some other reason, that's unexpected. The message
-            // of the day isn't very important though, so we just WARN and
-            // continue with the default in any case.
-            if err.kind() != std::io::ErrorKind::NotFound {
-                 tracing::warn!("could not read \"/etc/motd\": {err:?}");
-            }
-            "An old error is always more popular than a new truth. - German proverb"
-        }
-    }
-}
-```
-
-## Error types
-
-We use the `anyhow` crate widely. It contains many convenient macros
-like `bail!` and `ensure!` to construct and return errors, and to
-propagate many kinds of low-level errors, wrapped in `anyhow::Error`.
-
-A downside of `anyhow::Error` is that the caller cannot distinguish
-between different error cases. Most errors are propagated all the way
-to the mgmt API handler function, or the main loop that handles a
-connection with the compute node, and they are all handled the same
-way: the error is logged and returned to the client as an HTTP or
-libpq error.
-
-But in some cases, we need to distinguish between errors and handle
-them differently. For example, attaching a tenant to the pageserver
-could fail either because the tenant has already been attached, or
-because we could not load its metadata from cloud storage. The first
-case is more or less expected. The console sends the Attach request to
-the pageserver, and the pageserver completes the operation, but the
-network connection might be lost before the console receives the
-response. The console will retry the operation in that case, but the
-tenant has already been attached. It is important that the pagserver
-responds with the HTTP 403 Already Exists error in that case, rather
-than a generic HTTP 500 Internal Server Error.
-
-If you need to distinguish between different kinds of errors, create a
-new `Error` type. The `thiserror` crate is useful for that. But in
-most cases `anyhow::Error` is good enough.
-
-## Panics
-
-Depending on where a panic happens, it can cause the whole pageserver
-or safekeeper to restart, or just a single tenant. In either case,
-that is pretty bad and causes an outage. Avoid panics. Never use
-`unwrap()` or other calls that might panic, to verify inputs from the
-network or from disk.
-
-It is acceptable to use functions that might panic, like `unwrap()`, if
-it is obvious that it cannot panic. For example, if you have just
-checked that a variable is not None, it is OK to call `unwrap()` on it,
-but it is still preferable to use `expect("reason")` instead to explain
-why the function cannot fail.
-
-`assert!` and `panic!` are reserved for checking clear invariants and
-very obvious "can't happen" cases. When in doubt, use anyhow `ensure!`
-or `bail!` instead.
-
-## Error levels
-
-`tracing::Level` doesn't provide very clear guidelines on what the
-different levels mean, or when to use which level. Here is how we use
-them:
-
-### Error
-
-Examples:
-- could not open file "foobar"
-- invalid tenant id
-
-Errors are not expected to happen during normal operation. Incorrect
-inputs from client can cause ERRORs. For example, if a client tries to
-call a mgmt API that doesn't exist, or if a compute node sends passes
-an LSN that has already been garbage collected away.
-
-These should *not* happen during normal operations. "Normal
-operations" is not a very precise concept. But for example, disk
-errors are not expected to happen when the system is working, so those
-count as Errors. However, if a TCP connection to a compute node is
-lost, that is not considered an Error, because it doesn't affect the
-pageserver's or safekeeper's operation in any way, and happens fairly
-frequently when compute nodes are shut down, or are killed abruptly
-because of errors in the compute.
-
-**Errors are monitored, and always need human investigation to determine
-the cause.**
-
-Whether something should be logged at ERROR, WARNING or INFO level can
-depend on the callers and clients. For example, it might be unexpected
-and a sign of a serious issue if the console calls the
-"timeline_detail" mgmt API for a timeline that doesn't exist. ERROR
-would be appropriate in that case. But if the console routinely calls
-the API after deleting a timeline, to check if the deletion has
-completed, then it would be totally normal and an INFO or DEBUG level
-message would be more appropriate. If a message is logged as an ERROR,
-but it in fact happens frequently in production and never requires any
-action, it should probably be demoted to an INFO level message.
-
-### Warn
-
-Examples:
-- could not remove temporary file "foobar.temp"
-- unrecognized file "foobar" in timeline directory
-
-Warnings are similar to Errors, in that they should not happen
-when the system is operating normally. The difference between Error and
-Warning is that an Error means that the operation failed, whereas Warning
-means that something unexpected happened, but the operation continued anyway.
-For example, if deleting a file fails because the file already didn't exist,
-it should be logged as Warning.
-
-> **Note:** The python regression tests, under `test_regress`, check the
-> pageserver log after each test for any ERROR and WARN lines. If there are
-> any ERRORs or WARNs that have not been explicitly listed in the test as
-> allowed, the test is marked a failed. This is to catch unexpected errors
-> e.g. in background operations, that don't cause immediate misbehaviour in
-> the tested functionality.
-
-### Info
-
-Info level is used to log useful information when the system is
-operating normally. Info level is appropriate e.g. for logging state
-changes, background operations, and network connections.
-
-Examples:
-- "system is shutting down"
-- "tenant was created"
-- "retrying S3 upload"
-
-### Debug & Trace
-
-Debug and Trace level messages are not printed to the log in our normal
-production configuration, but could be enabled for a specific server or
-tenant, to aid debugging. (Although we don't actually have that
-capability as of this writing).
-
-## Context
-
-We use logging "spans" to hold context information about the current
-operation. Almost every operation happens on a particular tenant and
-timeline, so we enter a span with the "tenant_id" and "timeline_id"
-very early when processing an incoming API request, for example. All
-background operations should also run in a span containing at least
-those two fields, and any other parameters or information that might
-be useful when debugging an error that might happen when performing
-the operation.
-
-TODO: Spans are not captured in the Error when it is created, but when
-the error is logged. It would be more useful to capture them at Error
-creation. We should consider using `tracing_error::SpanTrace` to do
-that.
-
-## Error message style
-
-PostgreSQL has a style guide for writing error messages:
-
-https://www.postgresql.org/docs/current/error-style-guide.html
-
-Follow that guide when writing error messages in the PostgreSQL
-extension. We don't follow it strictly in the pageserver and
-safekeeper, but the advice in the PostgreSQL style guide is generally
-good, and you can't go wrong by following it.

-# Storage messaging
-
-Safekeepers need to communicate to each other to
-* Trim WAL on safekeepers;
-* Decide on which SK should push WAL to the S3;
-* Decide on when to shut down SK<->pageserver connection;
-* Understand state of each other to perform peer recovery;
-
-Pageservers need to communicate to safekeepers to decide which SK should provide
-WAL to the pageserver.
-
-This is an iteration on [015-storage-messaging](https://github.com/neondatabase/neon/blob/main/docs/rfcs/015-storage-messaging.md) describing current situation,
-potential performance issue and ways to address it.
-
-## Background
-
-What we have currently is very close to etcd variant described in
-015-storage-messaging. Basically, we have single `SkTimelineInfo` message
-periodically sent by all safekeepers to etcd for each timeline.
-* Safekeepers subscribe to it to learn status of peers (currently they subscribe to
-  'everything', but they can and should fetch data only for timelines they hold).
-* Pageserver subscribes to it (separate watch per timeline) to learn safekeepers
-  positions; based on that, it decides from which safekeepers to pull WAL.
-
-Also, safekeepers use etcd elections API to make sure only single safekeeper
-offloads WAL.
-
-It works, and callmemaybe is gone. However, this has a performance
-hazard. Currently deployed etcd can do about 6k puts per second (using its own
-`benchmark` tool); on my 6 core laptop, while running on tmpfs, this gets to
-35k. Making benchmark closer to our usage [etcd watch bench](https://github.com/arssher/etcd-client/blob/watch-bench/examples/watch_bench.rs),
-I get ~10k received messages per second with various number of publisher-subscribers
-(laptop, tmpfs). Diving this by 12 (3 sks generate msg, 1 ps + 3 sk consume them) we
-get about 800 active timelines, if message is sent each second. Not extremely
-low, but quite reachable.
-
-A lot of idle watches seem to be ok though -- which is good, as pageserver
-subscribes to all its timelines regardless of their activity.
-
-Also, running etcd with fsyncs disabled is messy -- data dir must be wiped on
-each restart or there is a risk of corruption errors.
-
-The reason is etcd making much more than what we need; it is a fault tolerant
-store with strong consistency, but I claim all we need here is just simplest pub
-sub with best effort delivery, because
-* We already have centralized source of truth for long running data, like which
-  tlis are on which nodes  -- the console.
-* Momentary data (safekeeper/pageserver progress) doesn't make sense to persist.
-  Instead of putting each change to broker, expecting it to reliably deliver it
-  is better to just have constant flow of data for active timelines: 1) they
-  serve as natural heartbeats -- if node can't send, we shouldn't pull WAL from
-  it 2) it is simpler -- no need to track delivery to/from the broker.
-  Moreover, latency here is important: the faster we obtain fresh data, the
-  faster we can switch to proper safekeeper after failure.
-* As for WAL offloading leader election, it is trivial to achieve through these
-  heartbeats -- just take suitable node through deterministic rule (min node
-  id).  Once network is stable, this is a converging process (well, except
-  complicated failure topology, but even then making it converge is not
-  hard). Such elections bear some risk of several offloaders running
-  concurrently for a short period of time, but that's harmless.
-
-  Generally, if one needs strong consistency, electing leader per se is not
-  enough; it must be accompanied with number (logical clock ts), checked at
-  every action to track causality. s3 doesn't provide CAS, so it can't
-  differentiate old/new leader, this must be solved differently.
-
-  We could use etcd CAS (its most powerful/useful primitive actually) to issue
-  these leader numbers (and e.g. prefix files in s3), but currently I don't see
-  need for that.
-
-
-Obviously best effort pub sub is much more simpler and performant; the one proposed is
-
-## gRPC broker
-
-I took tonic and [prototyped](https://github.com/neondatabase/neon/blob/asher/neon-broker/broker/src/broker.rs) the replacement of functionality we currently use
-with grpc streams and tokio mpsc channels. The implementation description is at the file header.
-
-It is just 500 lines of code and core functionality is complete. 1-1 pub sub
-gives about 120k received messages per second; having multiple subscribers in
-different connecitons quickly scales to 1 million received messages per second.
-I had concerns about many concurrent streams in singe connection, but 2^20
-subscribers still work (though eat memory, with 10 publishers 20GB are consumed;
-in this implementation each publisher holds full copy of all subscribers). There
-is `bench.rs` nearby which I used for testing.
-
-`SkTimelineInfo` is wired here, but another message can be added (e.g. if
-pageservers want to communicate with each other) with templating.
-
-### Fault tolerance
-
-Since such broker is stateless, we can run it under k8s. Or add proxying to
-other members, with best-effort this is simple.
-
-### Security implications
-
-Communication happens in a private network that is not exposed to users;
-additionaly we can add auth to the broker.
-
-## Alternative: get existing pub-sub
-
-We could take some existing pub sub solution, e.g. RabbitMQ, Redis. But in this
-case IMV simplicity of our own outweights external dependency costs (RabbitMQ is
-much more complicated and needs VM; Redis Rust client maintenance is not
-ideal...). Also note that projects like CockroachDB and TiDB are based on gRPC
-as well.
-
-## Alternative: direct communication
-
-Apart from being transport, broker solves one more task: discovery, i.e. letting
-safekeepers and pageservers find each other. We can let safekeepers know, for
-each timeline, both other safekeepers for this timeline and pageservers serving
-it. In this case direct communication is possible:
- - each safekeeper pushes to each other safekeeper status of timelines residing
-   on both of them, letting remove WAL, decide who offloads, decide on peer
-   recovery;
- - each safekeeper pushes to each pageserver status of timelines residing on
-   both of them, letting pageserver choose from which sk to pull WAL;
-
-It was mostly described in [014-safekeeper-gossip](https://github.com/neondatabase/neon/blob/main/docs/rfcs/014-safekeepers-gossip.md), but I want to recap on that.
-
-The main pro is less one dependency: less moving parts, easier to run Neon
-locally/manually, less places to monitor. Fault tolerance for broker disappears,
-no kuber or something. To me this is a big thing.
-
-Also (though not a big thing) idle watches for inactive timelines disappear:
-naturally safekeepers learn about compute connection first and start pushing
-status to pageserver(s), notifying it should pull.
-
-Importantly, I think that eventually knowing and persisting peers and
-pageservers on safekeepers is inevitable:
-- Knowing peer safekeepers for the timeline is required for correct
-  automatic membership change -- new member set must be hardened on old
-  majority before proceeding. It is required to get rid of sync-safekeepers
-  as well (peer recovery up to flush_lsn).
-- Knowing pageservers where the timeline is attached is needed to
-  1. Understand when to shut down activity on the timeline, i.e. push data to
-     the broker. We can have a lot of timelines sleeping quietly which
-	 shouldn't occupy resources.
-  2. Preserve WAL for these (currently we offload to s3 and take it from there,
-     but serving locally is better, and we get one less condition on which WAL
-     can be removed from s3).
-
-I suppose this membership data should be passed to safekeepers directly from the
-console because
-1. Console is the original source of this data, conceptually this is the
-   simplest way (rather than passing it through compute or something).
-2. We already have similar code for deleting timeline on safekeepers
-   (and attaching/detaching timeline on pageserver), this is a typical
-   action -- queue operation against storage node and execute it until it
-   completes (or timeline is dropped).
-
-Cons of direct communication are
-- It is more complicated: each safekeeper should maintain set of peers it talks
-  to, and set of timelines for each such peer -- they ought to be multiplexed
-  into single connection.
-- Totally, we have O(n^2) connections instead of O(n) with broker schema
-  (still O(n) on each node). However, these are relatively stable, async and
-  thus not very expensive, I don't think this is a big problem. Up to 10k
-  storage nodes I doubt connection overhead would be noticeable.
-
-I'd use gRPC for direct communication, and in this sense gRPC based broker is a
-step towards it.

-# Managing Tenant and Timeline lifecycles
-
-## Summary
-
-The pageserver has a Tenant object in memory for each tenant it manages, and a
-Timeline for each timeline. There are a lot of tasks that operate on the tenants
-and timelines with references to those objects. We have some mechanisms to track
-which tasks are operating on each Tenant and Timeline, and to request them to
-shutdown when a tenant or timeline is deleted, but it does not cover all uses,
-and as a result we have many race conditions around tenant/timeline shutdown.
-
-## Motivation
-
-We have a bunch of race conditions that can produce weird errors and can be hard
-to track down.
-
-## Non Goals
-
-This RFC only covers the problem of ensuring that a task/thread isn't operating
-on a Tenant or Timeline. It does not cover what states, aside from Active and
-non-Active, each Tenant and Timeline should have, or when exactly the transitions
-should happen.
-
-## Impacted components (e.g. pageserver, safekeeper, console, etc)
-
-Pageserver. Although I wonder if the safekeeper should have a similar mechanism.
-
-## Current situation
-
-Most pageserver tasks of are managed by task_mgr.rs:
-
-- LibpqEndpointListener
-- HttpEndPointListener
-- WalReceiverManager and -Connection
-- GarbageCollector and Compaction
-- InitialLogicalSizeCalculation
-
-In addition to those tasks, the walreceiver performs some direct tokio::spawn
-calls to spawn tasks that are not registered with 'task_mgr'. And all of these
-tasks can spawn extra operations with tokio spawn_blocking.
-
-Whenever a tenant or timeline is removed from the system, by pageserver
-shutdown, delete_timeline or tenant-detach operation, we rely on the task
-registry in 'task_mgr.rs' to wait until there are no tasks operating on the
-tenant or timeline, before its Tenant/Timeline object is removed. That relies on
-each task to register itself with the tenant/timeline ID in
-'task_mgr.rs'. However, there are many gaps in that. For example,
-GarbageCollection and Compaction tasks are registered with the tenant, but when
-they proceed to operate on a particular timeline of the tenant, they don't
-register with timeline ID. Because of that, the timeline can be deleted while GC
-or compaction is running on it, causing failures in the GC or compaction (see
-https://github.com/neondatabase/neon/issues/2442).
-
-Another problem is that the task registry only works for tokio Tasks. There is
-no way to register a piece of code that runs inside spawn_blocking(), for
-example.
-
-## Proposed implementation
-
-This "voluntary" registration of tasks is fragile. Let's use Rust language features
-to enforce that a tenant/timeline cannot be removed from the system when there is
-still some code operating on it.
-
-Let's introduce new Guard objects for Tenant and Timeline, and do all actions through
-the Guard object. Something like:
-
-TenantActiveGuard: Guard object over Arc<Tenant>. When you acquire the guard,
-the code checks that the tenant is in Active state. If it's not, you get an
-error. You can change the state of the tenant to Stopping while there are
-ActiveTenantGuard objects still on it, to prevent new ActiveTenantGuards from
-being acquired, but the Tenant cannot be removed until all the guards are gone.
-
-TenantMaintenanceGuard: Like ActiveTenantGuard, but can be held even when the
-tenant is not in Active state. Used for operations like attach/detach. Perhaps
-allow only one such guard on a Tenant at a time.
-
-Similarly for Timelines. We don't currentl have a "state" on Timeline, but I think
-we need at least two states: Active and Stopping. The Stopping state is used at
-deletion, to prevent new TimelineActiveGuards from appearing, while you wait for
-existing TimelineActiveGuards to die out.
-
-The shutdown-signaling, using shutdown_watcher() and is_shutdown_requested(),
-probably also needs changes to deal with the new Guards. The rule is that if you
-have a TenantActiveGuard, and the tenant's state changes from Active to
-Stopping, the is_shutdown_requested() function should return true, and
-shutdown_watcher() future should return.
-
-This signaling doesn't neessarily need to cover all cases. For example, if you
-have a block of code in spawn_blocking(), it might be acceptable if
-is_shutdown_requested() doesn't return true even though the tenant is in
-Stopping state, as long as the code finishes reasonably fast.

-# Coordinating access of multiple pageservers to the same s3 data
-
-## Motivation
-
-There are some blind spots around coordinating access of multiple pageservers
-to the same s3 data. Currently this is applicable only to tenant relocation
-case, but in the future we'll need to solve similar problems for
-replica/standby pageservers.
-
-## Impacted components (e.g. pageserver, safekeeper, console, etc)
-
-Pageserver
-
-## The problem
-
-### Relocation
-
-During relocation both pageservers can write to s3. This should be ok for all
-data except the `index_part.json`. For index part it causes problems during
-compaction/gc because they remove files from index/s3.
-
-Imagine this case:
-
-```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 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)
-
-### Standby pageserver
-
-Another related case is standby pageserver. In this case second pageserver can
-be used as a replica to scale reads and serve as a failover target in case
-first one fails.
-
-In this mode second pageserver needs to have the same picture of s3 files to
-be able to load layers on-demand. To accomplish that second pageserver
-cannot run gc/compaction jobs. Instead it needs to receive updates for index
-contents. (There is no need to run walreceiver on the second pageserver then).
-
-## Observations
-
-- If both pageservers ingest wal then their layer set diverges, because layer
-  file generation is not deterministic
-- If one of the pageservers does not ingest wal (and just picks up layer
-  updates) then it lags behind and cannot really answer queries in the same
-  pace as the primary one
-- Can compaction help make layers deterministic? E g we do not upload level
-  zero layers and construction of higher levels should be deterministic.
-  This way we can guarantee that layer creation by timeout wont mess things up.
-  This way one pageserver uploads data and second one can just ingest it.
-  But we still need some form of election
-
-## Solutions
-
-### Manual orchestration
-
-One possible solution for relocation case is to orchestrate background jobs
-from outside. The oracle who runs migration can turn off background jobs on
-PS1 before migration and then run migration -> enable them on PS2. The problem
-comes if migration fails. In this case in order to resume background jobs
-oracle needs to guarantee that PS2 doesnt run background jobs and if it doesnt
-respond then PS1 is stuck unable to run compaction/gc. This cannot be solved
-without human ensuring that no upload from PS2 can happen. In order to be able
-to resolve this automatically CAS is required on S3 side so pageserver can
-avoid overwriting index part if it is no longer the leading one
-
-Note that flag that disables background jobs needs to be persistent, because
-otherwise pageserver restart will clean it
-
-### Avoid index_part.json
-
-Index part consists of two parts, list of layers and metadata. List of layers
-can be easily obtained by `ListObjects` S3 API method. But what to do with
-metadata? Create metadata instance for each checkpoint and add some counter
-to the file name?
-
-Back to potentially long s3 ls.
-
-### Coordination based approach
-
-Do it like safekeepers chose leader for WAL upload. Ping each other and decide
-based on some heuristics e g smallest node id. During relocation PS1 sends
-"resign" ping message so others can start election without waiting for a timeout.
-
-This still leaves metadata question open and non deterministic layers are a
-problem as well
-
-### Avoid metadata file
-
-One way to eliminate metadata file is to store it in layer files under some
-special key. This may resonate with intention to keep all relation sizes in
-some special segment to avoid initial download during size calculation.
-Maybe with that we can even store pre calculated value.
-
-As a downside each checkpoint gets 512 bytes larger.
-
-If we entirely avoid metadata file this opens up many approaches
-
-* * *
-
-During discussion it seems that we converged on the approach consisting of:
-
-- index files stored per pageserver in the same timeline directory. With that
-  index file name starts to look like: `<pageserver_node_id>_index_part.json`.
-  In such set up there are no concurrent overwrites of index file by different
-  pageservers.
-- For replica pageservers the solution would be for primary to broadcast index
-  changes to any followers with an ability to check index files in s3 and
-  restore the full state. To properly merge changes with index files we can use
-  a counter that is persisted in an index file, is incremented on every change
-  to it and passed along with broadcasted change. This way we can determine
-  whether we need to apply change to the index state or not.
-- Responsibility for running background jobs is assigned externally. Pageserver
-  keeps locally persistent flag for each tenant that indicates whether this
-  pageserver is considered as primary one or not. TODO what happends if we
-  crash and cannot start for some extended period of time? Control plane can
-  assign ownership to some other pageserver. Pageserver needs some way to check
-  if its still the blessed one. Maybe by explicit request to control plane on
-  start.
-
-Requirement for deterministic layer generation was considered overly strict
-because of two reasons:
-
-- It can limit possible optimizations e g when pageserver wants to reshuffle
-  some data locally and doesnt want to coordinate this
-- The deterministic algorithm itself can change so during deployments for some
-  time there will be two different version running at the same time which can
-  cause non determinism
-
-### External elections
-
-The above case with lost state in this schema with externally managed
-leadership is represented like this:
-
-Note that here we keep objects list in the index file.
-
-```mermaid
-sequenceDiagram
-    autonumber
-    participant PS1
-    participant CP as Control Plane
-    participant S3
-    participant PS2
-
-    note over PS1,PS2: PS1 starts up and still a leader
-    PS1->>CP: Am I still the leader for Tenant X?
-    activate CP
-    CP->>PS1: Yes
-    deactivate CP
-    PS1->>S3: Fetch PS1 index.
-    note over PS1: Continue operations, start backround jobs
-    note over PS1,PS2: PS1 starts up and still and is not a leader anymore
-    PS1->>CP: Am I still the leader for Tenant X?
-    CP->>PS1: No
-    PS1->>PS2: Subscribe to index changes
-    PS1->>S3: Fetch PS1 and PS2 indexes
-    note over PS1: Combine index file to include layers <br> from both indexes to be able <br> to see newer files from leader (PS2)
-    note over PS1: Continue operations, do not start background jobs
-```
-
-### Internal elections
-
-To manage leadership internally we can use broker to exchange pings so nodes
-can decide on the leader roles. In case multiple pageservers are active leader
-is the one with lowest node id.
-
-Operations with internally managed elections:
-
-```mermaid
-sequenceDiagram
-    autonumber
-    participant PS1
-    participant S3
-
-    note over PS1: Starts up
-    note over PS1: Subscribes to changes, waits for two ping <br> timeouts to see if there is a leader
-    PS1->>S3: Fetch indexes from s3
-    alt there is a leader
-        note over PS1: do not start background jobs, <br> continue applying index updates
-    else there is no leader
-        note over PS1: start background jobs, <br> broadcast index changes
-    end
-
-    note over PS1,S3: Then the picture is similar to external elections <br> the difference is that follower can become a leader <br> if there are no pings after some timeout new leader gets elected
-```
-
-### Eviction
-
-When two pageservers operate on a tenant for extended period of time follower
-doesnt perform write operations in s3. When layer is evicted follower relies
-on updates from primary to get info about layers it needs to cover range for
-evicted layer.
-
-Note that it wont match evicted layer exactly, so layers will overlap and
-lookup code needs to correctly handle that.
-
-### Relocation flow
-
-Actions become:
-
-- Attach tenant to new pageserver
-- New pageserver becomes follower since previous one is still leading
-- New pageserver starts replicating from safekeepers but does not upload layers
-- Detach is called on the old one
-- New pageserver becomes leader after it realizes that old one disappeared
-
-### Index File
-
-Using `s3 ls` on startup simplifies things, but we still need metadata, so we
-need to fetch index files anyway. If they contain list of files we can combine
-them and avoid costly `s3 ls`
-
-### Remaining issues
-
-- More than one remote consistent lsn for safekeepers to know
-
-Anything else?
-
-### Proposed solution
-
-To recap. On meeting we converged on approach with external elections but I
-think it will be overall harder to manage and will introduce a dependency on
-control plane for pageserver. Using separate index files for each pageserver
-consisting of log of operations and a metadata snapshot should be enough.
-
-### What we need to get there?
-
-- Change index file structure to contain log of changes instead of just the
-  file list
-- Implement pinging/elections for pageservers

     - Note that CI uses specific Python version (look for `PYTHON_VERSION` [here](https://github.com/neondatabase/docker-images/blob/main/rust/Dockerfile))
       so if you have different version some linting tools can yield different result locally vs in the CI.
