Subject [jira] [Commented] (CASSANDRA-5043) Small CollationController refactoring and CFS.getRawCachedRow(DecoratedKey) fix.
Date Tue, 11 Dec 2012 10:45:21 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-5043?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13528867#comment-13528867

Sylvain Lebresne commented on CASSANDRA-5043:
---------------------------------------------

Yes, that's what I was suggesting (except that the patch doesn't seem to apply to cassandra-1.2.0,
that I don't think we should use temp in the reduceNameFilter call and maybe we've want to
optimize for when there is only one source of columns (but maybe it's not worth bothering)).

> CollactionController can construct a factory on init based on mutableColumns parameter.
ArrayBackedSortedColumns proven to be better for counters as well as normal columns (row size
from 5 to 75 columns). CFS.getRawCachedRow would copy key byte array each time it contracts
a RowCacheKey so we want to avoid that where possible.
