Aleksey Yeschenko commented on CASSANDRA-13975: ----------------------------------------------- A straight-forward change pushed [here|https://github.com/iamaleksey/cassandra/commits/13975-3.0]. Unit test run [here|https://circleci.com/gh/iamaleksey/cassandra/63], dtest run [here|https://builds.apache.org/job/Cassandra-devbranch-dtest/407/]. > Add a workaround for overly large read repair mutations > ------------------------------------------------------- > > Key: CASSANDRA-13975 > URL: https://issues.apache.org/jira/browse/CASSANDRA-13975 > Project: Cassandra > Issue Type: Bug > Components: Coordination > Reporter: Aleksey Yeschenko > Assignee: Aleksey Yeschenko > Priority: Major > Fix For: 3.0.x, 3.11.x > > > It's currently possible for {{DataResolver}} to accumulate more changes to > read repair that would fit in a single serialized mutation. If that happens, > the node receiving the mutation would fail, and the read would time out, and > won't be able to proceed until the operator runs repair or manually drops the > affected partitions. > Ideally we should either read repair iteratively, or at least split the > resulting mutation into smaller chunks in the end. In the meantime, for > 3.0.x, I suggest we add logging to catch this, and a -D flag to allow > proceeding with the requests as is when the mutation is too large, without > read repair. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
