Date Wed, 01 May 2013 03:54:18 GMT

Pavel Yaskevich commented on CASSANDRA-5521:
--------------------------------------------

Have we considered using vint encoding on those arrays as we keep them in memory anyway to
minimize space consumption?

> 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.)
