Benedict commented on CASSANDRA-6477:
-------------------------------------

+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 unrepaired 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.
