Jonathan Ellis resolved CASSANDRA-3945. --------------------------------------- Resolution: Duplicate Assignee: (was: Chris Goffinet) CASSANDRA-5555 fixes this > Support incremental/batch sizes for BulkRecordWriter, due to GC overhead > issues > ------------------------------------------------------------------------------- > > Key: CASSANDRA-3945 > URL: https://issues.apache.org/jira/browse/CASSANDRA-3945 > Project: Cassandra > Issue Type: Bug > Reporter: Chris Goffinet > Priority: Minor > > When loading large amounts of data, currently the BulkRecordWriter will write > out all the sstables, then stream them. This actually caused us GC overhead > issues, due to our heap sizes for reducers. We ran into a problem where the > number of SSTables on disk that had to be open would cause the jvm process to > die. We also wanted a way to incrementally stream them as we created them. I > created support for setting this, the default behavior is wait for them to be > created. But if you increase to >= 1, you can determine the batch size. -- This message is automatically generated by JIRA.
