Erik Johnston	eba98fb024	Add functions to MultiWriterIdGen used by events stream (#8164)	2020-08-25 17:32:30 +01:00
Erik Johnston	76d21d14a0	Separate get_current_token into two. (#8113) ... The function is used for two purposes: 1) for subscribers of streams to get a token they can use to get further updates with, and 2) for replication to track position of the writers of the stream. For streams with a single writer the two scenarios produce the same result, however the situation becomes complicated for streams with multiple writers. The current `MultiWriterIdGenerator` does not correctly handle the first case (which is not an issue as its only used for the `caches` stream which nothing subscribes to outside of replication).	2020-08-19 10:39:31 +01:00

Erik Johnston	8123b2f909	Add MultiWriterIdGenerator. (#7281) ... This will be used to coordinate stream IDs across multiple writers. Functions as the equivalent of both `StreamIdGenerator` and `SlavedIdTracker`.	2020-05-04 17:17:45 +01:00
