[jira] Commented: (TS-560) ram cache compression should not be done
under the partition lock

----------------------------------
Cool! One question: Is it required that you have at least one "task" thread for this to work ? I'm wondering if we should keep the default to 0 task threads, which would schedule these continuations on the net threads instead. I know, it doesn't get you anything, but gives a user the option to decide. If it is required, then maybe we should have the number of task threads also be dependant on enabling cache compression?

---------------------------------
We could certainly do that.... it isn't like threads are expensive though, if they are not used.
We should add a comment at the compression option that it would be best to add one or
more task threads....

----------------------------------
I think that would be my vote. Incorporate the new change in records.config, but set it to 0 for now. We can always change this default later if necessary as well. But yeah, threads are fairly cheap, so either way is ok. (I just want to make sure that cache compression works even if this setting is set to 0, otherwise, we have an undocumented dependencies which could end up ugly).
