 ## Authentication
 
 ### Overview
-We use JWT tokens in communication between almost all components (compute, pageserver, safekeeper, CLI) regardless of the protocol used (HTTP/PostgreSQL).
-Etcd currently has no authentication.
-Authentication is optional and is disabled by default for easier debugging.
-It is used in some tests, though.
-Note that we do not cover authentication with `pg.neon.tech` here.
 
-For HTTP connections we use the Bearer authentication scheme.
-For PostgreSQL connections we expect the token to be passed as a password.
-There is a caveat for `psql`: it silently truncates passwords to 100 symbols, so to correctly pass JWT via `psql` you have to either use `PGPASSWORD` environment variable, or store password in `psql`'s config file.
-
-Current token scopes are described in `utils::auth::Scope`.
-There are no expiration or rotation schemes.
-
-_TODO_: some scopes allow both access to server management API and to the data.
-These probably should be split into multiple scopes.
-
-Tokens should not occur in logs.
-They may sometimes occur in configuration files, although this is discouraged
-because configs may be parsed and dumped into logs.
-
-#### Tokens generation and validation
-JWT tokens are signed using a private key.
-Compute/pageserver/safekeeper use the private key's public counterpart to validate JWT tokens.
-These components should not have access to the private key and may only get tokens from their configuration or external clients. 
-
-The key pair is generated once for an installation of compute/pageserver/safekeeper, e.g. by `neon_local init`.
-There is currently no way to rotate the key without bringing down all components.
-
-### CLI
-CLI generates a key pair during call to `neon_local init` with the following commands:
+Current state of authentication includes usage of JWT tokens in communication between compute and pageserver and between CLI and pageserver. JWT token is signed using RSA keys. CLI generates a key pair during call to `neon_local init`. Using following openssl commands:
 
 ```bash
-openssl genrsa -out auth_private_key.pem 2048
-openssl rsa -in auth_private_key.pem -pubout -outform PEM -out auth_public_key.pem
+openssl genrsa -out private_key.pem 2048
+openssl rsa -in private_key.pem -pubout -outform PEM -out public_key.pem
 ```
 
-Configuration files for all components point to `public_key.pem` for JWT validation.
-However, authentication is disabled by default.
-There is no way to automatically enable it everywhere, you have to configure each component individually.
+CLI also generates signed token and saves it in the config for later access to pageserver. Now authentication is optional. Pageserver has two variables in config: `auth_validation_public_key_path` and `auth_type`, so when auth type present and set to `NeonJWT` pageserver will require authentication for connections. Actual JWT is passed in password field of connection string. There is a caveat for psql, it silently truncates passwords to 100 symbols, so to correctly pass JWT via psql you have to either use PGPASSWORD environment variable, or store password in psql config file.
 
-CLI also generates signed token (full access to Pageserver) and saves it in
-the CLI's `config` file under `pageserver.auth_token`.
-Note that pageserver's config does not have any similar parameter.
-CLI is the only component which accesses that token.
-Technically it could generate it from the private key on each run,
-but it does not do that for some reason (_TODO_).
+Currently there is no authentication between compute and safekeepers, because this communication layer is under heavy refactoring. After this refactoring support for authentication will be added there too. Now safekeeper supports "hardcoded" token passed via environment variable to be able to use callmemaybe command in pageserver.
 
-### Compute
-#### Overview
-Compute is a per-timeline PostgreSQL instance, so it should not have
-any access to data of other tenants.
-All tokens used by a compute are restricted to a specific tenant.
-There is no auth isolation from other timelines of the same tenant,
-but a non-rogue client never accesses another timeline even by an accident:
-timeline IDs are random and hard to guess.
+Compute uses token passed via environment variable to communicate to pageserver and in the future to the safekeeper too.
 
-#### Incoming connections
-All incoming connections are from PostgreSQL clients.
-Their authentication is just plain PostgreSQL authentication and out of scope for this document.
+JWT authentication now supports two scopes: tenant and pageserverapi. Tenant scope is intended for use in tenant related api calls, e.g. create_branch. Compute launched for particular tenant also uses this scope. Scope pageserver api is intended to be used by console to manage pageserver. For now we have only one management operation - create tenant.
 
-There is no administrative API except those provided by PostgreSQL.
-
-#### Outgoing connections
-Compute connects to Pageserver for getting pages.
-The connection string is configured by the `neon.pageserver_connstring` PostgreSQL GUC, e.g. `postgresql://no_user:$ZENITH_AUTH_TOKEN@localhost:15028`.
-The environment variable inside the connection string is substituted with
-the JWT token.
-
-Compute connects to Safekeepers to write and commit data.
-The token is the same for all safekeepers.
-It's stored in an environment variable, whose name is configured
-by the `neon.safekeeper_token_env` PostgreSQL GUC.
-If the GUC is unset, no token is passed.
-
-Note that both tokens can be (and typically are) the same;
-the scope is the tenant and the token is usually passed through the
-`$ZENITH_AUTH_TOKEN` environment variable.
-
-### Pageserver
-#### Overview
-Pageserver keeps track of multiple tenants, each having multiple timelines.
-For each timeline, it connects to the corresponding Safekeeper.
-Information about "corresponding Safekeeper" is published by Safekeepers
-in the Etcd, but they do not publish access tokens, otherwise what is
-the point of authentication.
-
-Pageserver keeps a connection to some set of Safekeepers, which
-may or may not correspond to active Computes.
-Hence, we cannot obtain a per-timeline access token from a Compute.
-E.g. if the timeline's Compute terminates before all WAL is
-consumed by the Pageserver, the Pageserver continues consuming WAL.
-
-Pageserver replicas' authentication is the same as the main's.
-
-#### Incoming connections
-Pageserver listens for connections from computes.
-Each compute should present a token valid for the timeline's tenant.
-
-Pageserver also has HTTP API: some parts are per-tenant,
-some parts are server-wide, these are different scopes.
-
-The `auth_type` configuration variable in Pageserver's config may have
-either of three values:
-
-* `Trust` removes all authentication. The outdated `MD5` value does likewise
-* `NeonJWT` enables JWT validation.
-   Tokens are validated using the public key which lies in a PEM file
-   specified in the `auth_validation_public_key_path` config.
-
-#### Outgoing connections
-Pageserver makes a connection to a Safekeeper for each active timeline.
-As Pageserver may want to access any timeline it has on the disk,
-it is given a blanket JWT token to access any data on any Safekeeper.
-This token is passed through an environment variable called `ZENITH_AUTH_TOKEN`
-(non-configurable as of writing this text).
-
-A better way _may be_ to store JWT token for each timeline next to it,
-but may be not.
-
-### Safekeeper
-#### Overview
-Safekeeper keeps track of multiple tenants, each having multiple timelines.
-
-#### Incoming connections
-Safekeeper accepts connections from Compute/Pageserver, each
-connection corresponds to a specific timeline and requires
-a corresponding JWT token.
-
-Safekeeper also has HTTP API: some parts are per-tenant,
-some parts are server-wide, these are different scopes.
-
-The `auth-validation-public-key-path` command line options controls
-the authentication mode:
-
-* If the option is missing, there is no authentication or JWT token validation.
-* If the option is present, it should be a path to the public key PEM file used for JWT token validation.
-
-#### Outgoing connections
-No connections are initiated by a Safekeeper.
-
-### In the source code
-Tests do not use authentication by default.
-If you need it, you can enable it by configuring the test's environment:
+Examples for token generation in python:
 
 ```python
-neon_env_builder.auth_enabled = True
+# generate pageserverapi token
+management_token = jwt.encode({"scope": "pageserverapi"}, auth_keys.priv, algorithm="RS256")
+
+# generate tenant token
+tenant_token = jwt.encode({"scope": "tenant", "tenant_id": ps.initial_tenant}, auth_keys.priv, algorithm="RS256")
 ```
 
-You will have to generate tokens if you want to access components inside the test directly,
-use `AuthKeys.generate_*_token` methods for that.
-If you create a new scope, please create a new method to prevent mistypes in scope's name.
+Utility functions to work with jwts in rust are located in libs/utils/src/auth.rs

-# 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.

-# 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

-# Storage broker
-
-Storage broker targets two issues:
-- Allowing safekeepers and pageservers learn which nodes also hold their
-  timelines, and timeline statuses there.
-- Avoiding O(n^2) connections between storage nodes while doing so.
-
-This is used
-- By pageservers to determine the most advanced and alive safekeeper to pull WAL from.
-- By safekeepers to synchronize on the timeline: advance
-  `remote_consistent_lsn`, `backup_lsn`, choose who offloads WAL to s3.
-
-Technically, it is a simple stateless pub-sub message broker based on tonic
-(grpc) making multiplexing easy. Since it is stateless, fault tolerance can be
-provided by k8s; there is no built in replication support, though it is not hard
-to add.
-
-Currently, the only message is `SafekeeperTimelineInfo`. Each safekeeper, for
-each active timeline, once in a while pushes timeline status to the broker.
-Other nodes subscribe and receive this info, using it per above.
-
-Broker serves /metrics on the same port as grpc service. 
-
-grpcurl can be used to check which values are currently being pushed:
-```
-grpcurl -proto broker/proto/broker.proto -d '{"all":{}}' -plaintext localhost:50051 storage_broker.BrokerService/SubscribeSafekeeperInfo
-```
