> 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).
