> 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).
