Subject [jira] [Commented] (CASSANDRA-5043) Small CollationController refactoring and CFS.getRawCachedRow(DecoratedKey) fix.
Date Tue, 11 Dec 2012 08:43:21 GMT

Pavel Yaskevich commented on CASSANDRA-5043:
--------------------------------------------

I'm saying this because there a particular time-ordered workload involving multiple sstables
which shouldn't be all sorted and if assertion is not firing it could mean that something
is broken or assertions are disabled, I will double check that tomorrow.

> 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.
