Jack Krupansky commented on CASSANDRA-6477:
-------------------------------------------
Still waiting for an updated description for the ticket. In particular, what
specific use cases is this feature designed to handle well, and is it
definitively expert-only, or will there be use cases that are safe for normal
users. The key thing (ha ha!) is whether this feature will provide capabilities
to make it much easier for people to migrate from SQL to Cassandra in terms of
the denormalization process, and do it in a way that people can pick up easily
in Data Modeling 101 training. A couple of examples would help a lot - like
test cases.

> 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.
