                 Key: CASSANDRA-4047
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4047
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: 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.
