Samarth Jain commented on PHOENIX-1677:
---------------------------------------
+1 for getting it in 4.3.1. Although, it would be prudent to see if this
results in any perf impact especially for concurrent queries with high degree
of parallelism before this is committed.
> Immutable index deadlocks when number of guideposts are one half of thread
> pool size

> Key: PHOENIX-1677
> URL: https://issues.apache.org/jira/browse/PHOENIX-1677
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 5.0.0, 4.3
> Reporter: Mujtaba Chohan
> Assignee: James Taylor
> Attachments: PHOENIX-1677_utest.patch, PHOENIX-1677_v2.patch

>
> If total number of parallel iterators + mutation count exceeds Phoenix thread
> pool size then immutable index remains at 0 rows with no activity on client
> and server.
> Ex. Only with guide post count of 64 or lower does immutable index gets build
> with default 128 thread pool. By changing guide post width to get with >64
> guideposts, index fails to build. Also if thread pool size is lowered from
> 128 then index fails to build for 64 guide posts.
> Let me know if you need a utest as I think it would be easy to repro in it
> too.
