---------------------------------------------------------------
+Inf to what Sylvain just said. We should definitely step back and reassess all
the options.
Now, I think it is probably sufficient for correctness to perform our delta
generation on reconciliation of repaired with unrepaired data. Or, more simply:
to treat all repaired data we receive as needing delta-generation performed on
it. I don't _think_ at first blush this is more or less onerous than would be
required for any other approach, but I may be wrong. This definitely needs a
lot of thought.

> Local indexes are suitable for low-cardinality data, where spreading the
> index across the cluster is a Good Thing. However, for high-cardinality
> data, local indexes require querying most nodes in the cluster even if only a
> handful of rows is returned.
