Subject [jira] [Commented] (CASSANDRA-10024) Skip page cache for batchLog
Date Sat, 08 Aug 2015 18:26:46 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10024?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14663102#comment-14663102

Aleksey Yeschenko commented on CASSANDRA-10024:
-----------------------------------------------

Have you measured it having any effect?

Under normal operation, your should almost never have any batchlog entries hitting disk (except
as commit log entries) - memtable flushing has special cased code for just that.

And in 3.0 even less so, with explicit compaction at the end thrown out with CASSANDRA-7237,
and no more full scanning.

> We should skip the page cache for batch log. There could be more internal tables where
this might make sense.
