Brandon Williams commented on CASSANDRA-4047: --------------------------------------------- The tricky part is, who stores the hint? Since it's a non-member doing the streaming... I guess it could just choose some other target at random, but by the time it does that the sstable might already be compacted away. > Bulk hinting > ------------ > > Key: CASSANDRA-4047 > URL: https://issues.apache.org/jira/browse/CASSANDRA-4047 > Project: Cassandra > Issue Type: Improvement > Components: Core > Reporter: Brandon Williams > Assignee: Brandon Williams > Fix For: 1.2 > > > With the introduction of the BulkOutputFormat, there may be cases where > someone would like to tolerate node failures and have the job complete, but > afterwards since we streamed they have to repair or rely on read repair. We > don't currently have any way of hinting streams, but a node could take a > snapshot before acknowledging the stream session, then remember to send the > files in the snapshot to the unavailable nodes when they come back up. This > isn't quite ideal since of course the node may have compacted these files, > however it's much simpler than any sort of key tracking at this scale. -- This message is automatically generated by JIRA.
