Subject [jira] [Commented] (CASSANDRA-9500) SequentialWriter should extend BufferedDataOutputStreamPlus
Date Thu, 16 Jul 2015 15:37:05 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-9500?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14629897#comment-14629897

Benedict commented on CASSANDRA-9500:
-------------------------------------

[~aweisberg]: just wondering where this is on your priorities? It seems likely to be a pretty
contained piece of work but this class is absolutely fundamental to our performance behaviour.
Between this and CASSANDRA-8630 we might plausibly see a huge impact to our currently woeful
compaction throughput.

> SequentialWriter is the last piece left not implementing DataOutputStreamPlus. It should
not be too tricky to extend it, and it should result in improved write throughput. Further,
it will permit it to exploit the more efficient implementation of writeVInt being delivered
in CASSANDRA-9499
