Subject [jira] [Commented] (CASSANDRA-3171) AbstractCompactionIterable uses a 1MB buffer for every sstable
Date Fri, 09 Sep 2011 20:04:08 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3171?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13101524#comment-13101524
] 

Jonathan Ellis commented on CASSANDRA-3171:
-------------------------------------------

Is there anywhere we actually need non-default buffer sizes?  I think we should probably rip
out that constructor parameter (on both RAR and SW) to force everyone to be sane whether they
like it or not.

See also: the 10MB buffer in streaming and the 8MB one in IndexWriter.

> This causes an OOM for any compaction task that needs to open all the sstables when you
have a lot of them (repair, major, etc)
