Josh Elser commented on HBASE-17527:
------------------------------------
bq. making it so you can set policy with commands to ITBLL (only!) is just
short-sighted. We have a swath of IT jobs. I have to go edit each of those
individually to do as here if I want to test inmemory options as is done here
That's a good point.
bq. Even if it were to be off by default – we want it to be on by default
Suggestions on how you'd expect to see this controlled by users, [~stack]?
Thinking something like a Java system property? e.g.
{{-Dhbase.compaction.policy=MEMORY}} would be a "hidden" developer hook that
could affect all instances of HTD/HCD? Obviously, we're making this for our
benefit, not the users'.
bq. Once we have enough confidence, in memory compaction can be turned on by
default.
Also to Stack's point, having confidence in the ITs running with this option
would be nice.
