Sylvain Lebresne commented on CASSANDRA-6477:
---------------------------------------------
[brianmhess] Yes typically.
And to clarify, I'm not saying lifting that constraint is impossible or
unthinkable, just that we shouldn't lift it before having made sure it's 1)
actually useful and 2) not gonna limit us in the future.

> 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.
