Jeremy Hanna commented on CASSANDRA-2527: ----------------------------------------- I remember the acunu guys talking about having point-in-time versioning for sstables. That would be a helpful feature for doing something like this. > Add ability to snapshot data as input to hadoop jobs > ---------------------------------------------------- > > Key: CASSANDRA-2527 > URL: https://issues.apache.org/jira/browse/CASSANDRA-2527 > Project: Cassandra > Issue Type: Improvement > Reporter: Jeremy Hanna > Labels: hadoop > > It is desirable to have immutable inputs to hadoop jobs for the duration of > the job. That way re-execution of individual tasks do not alter the output. > One way to accomplish this would be to snapshot the data that is used as > input to a job. -- This message is automatically generated by JIRA.
