It may simply have been to minimise the change in semantics to {{system.paxos}}, without there having been any particularly good reason. Perhaps also for debugging purposes, it helps to be able to see whether something had been promised before it was accepted/committed. was (Author: benedict): I think this would be fine, I need to think through why I did not do this originally, as I did consider it. It may simply have been to minimise the change in semantics to {{system.paxos}}, without there having been any particularly good reason. Perhaps also for debugging purposes, it helps to be able to see whether something had been promised before it was accepted/committed. I think there is perhaps also some additional complexity when a replica has promised a ballot with a timestamp, and then proceeds to accept a different one with the same timestamp. I don't think we would resolve these reliably, so we might not actually overwrite it anyway, and I don't think there is a trivial solution to this problem in the storage layer. I'm not certain if this would actually cause problems, but it would require some careful consideration to rule it out. > CEP-14: Paxos Improvements > -------------------------- > > Key: CASSANDRA-17164 > URL: https://issues.apache.org/jira/browse/CASSANDRA-17164 > Project: Cassandra > Issue Type: Improvement > Components: Consistency/Coordination, Consistency/Repair > Reporter: Benedict Elliott Smith > Assignee: Benedict Elliott Smith > Priority: Normal > Fix For: 4.1 > > > This ticket encompasses work for [CEP-14| > https://cwiki.apache.org/confluence/display/CASSANDRA/CEP-14%3A+Paxos+Improvements]. -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
