Edward Bortnikov commented on HBASE-16417:
------------------------------------------
[~eshcar], thanks for the thorough report, great stuff.
Question to all - do these results suggest that we change the default to
BASIC+MERGE? Seems that this method does not have any material overhead, even
under the uniform workload. If the answer is "yes", we could take one of two
ways: (1) say that BASIC+MERGE is a new BASIC (my favorite :)), or (2)
introduce a new compaction level (MODERATE?). Let's converge fast - then we can
update the documentation and finalize the code.
This work notwithstanding, it is still appealing to come up with an automatic
policy to tune handsfree (which was the original intent behind this JIRA). With
the 2.0 release on our heels, we might not be able to make it until then. But
let's have all the building blocks in place, at least (smile).
