Aleksey Yeschenko commented on CASSANDRA-6477:
----------------------------------------------
Didn't mean to actually add it as a new {{Flag}} enum field - only a boolean in
{{CFMetaData}} (and we want want for {{isIndex}} too, instead of the hack with
the name, but it's unrelated to the ticket). It being an actual extra thing in
the enum is meaningless, since tables in {{system_schema.tables}} will never
have it, and views in the future {{system_schema.materialized_views}}, always
will (no need to store it).
But it's good enough for now (will have to go before CASSANDRA-9921, though).
Thrift validation is still lacking. In particular
{{system_update_column_family}} and {{system_drop_column_family}}. Some tests
by someone would be nice (not alpha-blocking).
{{SelectStatement}} is still not asking for {{SELECT}} on the base table for
MVs.

> 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.
