Jonathan Shook commented on CASSANDRA-6477:
-------------------------------------------
The comment about adding a hop was with respect to what users would currently
be doing to maintain multiple views of data. They don't expect that there is a
proxy proxy for their writes, no matter whether they are using async or not,
batches or not.

> 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.
