Andrew Purtell commented on PHOENIX-3790:
-----------------------------------------
[~giacomotaylor] [~gjacoby] Wouldn't it be fair to say if there is an index
defined on a Phoenix table then a mutation with durability of SKIP_WAL can just
be ignored? The Durability thing is just a hint, that WAL entries are not
_required_. If there are indexes, we could require them nonetheless. Something
to think about.

> URL: https://issues.apache.org/jira/browse/PHOENIX-3790
> Project: Phoenix
> Issue Type: Bug
> Reporter: James Taylor
>
> A corner case related to PHOENIX-3789. Non transactional, mutable secondary
> index maintenance relies on the the WAL edit as state so that the actual
> index writes can be done later. When WAL edits are disabled, the writes to
> the index table are done in the preBatchMutation while the row locks are
> still held which should be avoided.
> This can be fixed by either leveraging a way of passing state between
> coprocessor hooks (which I'm not sure exists) or through thread locals as a
> last resort.
