Jack Krupansky commented on CASSANDRA-6477:
-------------------------------------------
1. Has a decision been made on refresh modes? It sounds like the focus is on
"always consistent", as opposed to manual refresh or one-time without refresh
or on some time interval, but is that simply the default, preferred refresh
mode, or the only mode that will be available (initially)?
2. What happens if an MV is created for a base table that is already populated?
Will the operation block while all existing data is propagated to the MV, or
will that propagation happen in the background (in which case, is there a way
to monitor its status and completion?), or is that not supported (initially)?

> 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.
