-# 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.
