Ivo Ladage - van Doorn updated AMDATUCASSANDRA-132:
---------------------------------------------------
Attachment: AMDATUCASSANDRA-132-2.patch
Added a new version of the patch. The new implementation of getRowKeys appeared
to return tombstone records, which were not returned before. To detect if a
record is a tombstone record, at least one column still needs to be
deserialized. So the new way may be much quicker, but does not provide the
desired behavior. So reverted this part of the patch.

> The getSuperRow methods set the query row count to 1,000,000. Cassandra
> creates an ArrayList of the same size for handling this number of rows. This
> leads to at least 4MB of garbage for each invocation.
