Subject [jira] [Commented] (HBASE-18906) Investigate Phoenix usages of Region#waitForXXX APIs
Date Tue, 10 Oct 2017 02:38:03 GMT

Duo Zhang commented on HBASE-18906:

- Request flush async
- Request compaction async
- Poll for the completion of a single flush request
- Poll for the completion of a single compaction request

So at least we need to provide these abilities. [~anoopsamjohn] so let's finish HBASE-18183
and then start working on this? I think the patch of HBASE-18183 does not need to be perfect,
it is big enough... Can polish in follow on issues.

Thanks.

> While reviewing HBASE-18183, Andy pointed out that Phoenix uses waitForFlushesAndCompactions
and/or waitForFlushes for diff reasons.  This issue is to see why they need them and whether
alternate ways are possible. This seems to be too much internal stuff and a normal CP hook
calling these would be dangerous.
> If there are alternate ways for Phoenix not to use this and not landing in issues (As
said by Andy) we should suggest/fix for them.
