Can you provide a link? Only thing I see on Couchbase is for NoSQL databases.

Lemmy Server Performance@lemmy.ml•Lemmy PERFORMANCE CRISIS: popular instances with many remote instances following big communities could stop federating outbound for Votes on comments/posts - code path identified
2·2 years agoThanks for doing all this.
Do we have any real numbers from a real server? How many votes are trying to be federated to how many servers?
Just ballparking some approximate numbers:
- !technology@lemmy.world
- 15k subscribers
- 4000 subscribed servers
- 10 votes per subscriber per day
15000 * 4000 * 10 = 600,000,000 federated actions. That is around 7,000 per second 24/7 for one community.
IMO, this real time federation just doesn’t scale. We need to start planning the specs for federation batching.
Thanks for checking.
We don’t need full database replication. We are just replicating activities that other servers are subscribed to. So the Comments table, only some of the rows will be “replicated”. Not sure if/how CouchBase handles this.
