Subject Re: C* 3.0.7 - Compactions pending after TRUNCATE
Date Thu, 30 Jun 2016 09:25:40 GMT
Small update:

I have managed to attach a thread dump.
Looks like the compaction threads are just waiting for work.

My understanding is that, since the SStables got deleted, the compaction
tasks that were once pending are currently stuck.
I've also tried to flush the memtable so to have one SStable at least, but
the pending tasks are still stuck though.

Regards,
Stefano
