James Taylor updated PHOENIX-2221:
----------------------------------
Attachment: PHOENIX-2221_v7.patch
[~ayingshu] - your test isn't correct. See my attached patch:
- you should be able to just disable the index table rather than delete it (as
that way you'd be testing partial index build - otherwise the entire index
needs to get rebuilt). For some reason the commit hangs if the index table is
only disabled. Need to figure out why.
- the commit should fail after you disable the index table, but it looks to be
succeeding. That's not correct.
- only a single row should be returned from the query after that as the
timestamp should be set such that you wouldn't see the committed data.
My patch makes some minor improvements in other areas, but you need to figure
out why the above isn't working.

> In one usecase, it was deemed better to not accept writes when the index
> regions are unavailable for any reason (as opposed to disabling the index and
> the queries doing bigger data-table scans).
> The idea is that the index regions are kept consistent with the data regions,
> and when a query runs against the index regions, one can be reasonably sure
> that the query ran with the most recent data in the data regions. When the
> index regions are unavailable, the writes to the data table are rejected.
> Read queries off of the index regions would have deterministic performance
> (and on the other hand if the index is disabled, then the read queries would
> have to go to the data regions until the indexes are rebuilt, and the queries
> would suffer).
