belliottsmith opened a new pull request, #158:
URL: https://github.com/apache/cassandra-accord/pull/158
- detect and save whether RX can be used as a GC bound for HLCs
- have RX durably record if they witnessed any superseding epoch and use
this for HLC GC
- rework GC to retain applyAt for writes
Also improve:
- PreCommitted overwrites fast path vote, then loses tie-break with
NotAccept, so we don't recover
- track executeAtLeast and uniqueHlc separately from WaitingOn in
CommandChange
- Always propose executeAt.hlc() >= txnId.hlc() Also fix:
- Dangling recovery when Commit rejected
- Failed epoch fetch handling in DefaultProgressLog
- CommandsForKey must track Accept executeAt for computing earlierWait
collection on recovery
