Subject [jira] [Commented] (CASSANDRA-5521) move IndexSummary off heap
Date Wed, 01 May 2013 23:56:15 GMT


Pavel Yaskevich commented on CASSANDRA-5521:

if we do so we would have to change partitioner interface to decorateKey and getToken, DecoratedKey
to have two "key" fields and change at least MurmurHash to accept both BB and M at the same
time. I'm my opinion it's just too many changes just because we don't require JNA but with
hybrid approach we don't have to do any of that work. Besides mentioned users would want to
run with JNA in production anyway.

> IndexSummary can still use a lot of heap for narrow-row sstables.  (It can also contribute
to memory fragmentation because of the large arrays it creates.)
