Anoop Sam John commented on HBASE-17575:
----------------------------------------
Did u do a performance test comparing NONE vs BASIC using PE tool (Where it is
not a duplicated cells case).. We are doing these tests extensively these
days. (With off heaping enabled also) Could not see much improve wrt
throughput. Though the GC was looking much better with BASIC.. Will do more
tests.. Just asking whether u have any such readings

> Towards Making BASIC the Default In-Memory Compaction Policy

> In preparation for switching the default in-memory compaction policy to
> BASIC, we would like to make sure that once we do the switch all tests will
> run (and pass!) with the new default policy.
> To this end, we remove the NONE configuration setting added to tests in
> HBASE-17294 and HBASE-17316.
> We verified these tests pass with all 3 memory compaction policies.
> For each test
> (1) if all 3 policies pass the test -- we remove the configuration from the
> test.
> (2) if some fail we add tests of all 3 configurations, e.g., by parameterized
> tests. When needed we update expected results.
> One test failure identified a small bug which is also fixed in the patch.
