Ivo Ladage - van Doorn updated AMDATUCASSANDRA-132:
---------------------------------------------------
Attachment: AMDATUCASSANDRA-132.patch
Attached patch that resolves the issue:
- Removed setting the row limit
- Refactored getRowKeys to use a range slice query with returnKeysOnly set to
true
- Deprecated getRowKeys(String, String, String), as it now does exactly the
same as getRowKeys(String)
- Removed the InitService which dropped the test keyspace prior to running the
test, but this could lead to problems
- Refactored the performance test bundle to test all PM methods
- Refactored performance test to not create private CF's anymore, but use one
global CF instead
> Excessive garbage allocation in getSuperRow method
> --------------------------------------------------

> 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.
