Aleksey Yeschenko commented on CASSANDRA-6477:
----------------------------------------------
I see it mostly used for the automated denormalization, tbh, and not for the
KEYS part, so I'd argue that materialized views is a more fitting name.
Plus, with the upcoming SASI changes, there would be a huge gap between what
local indexes/materialized views offer, in terms of expressiveness, and calling
both 'indexes' would bring on more confusion in the long term.
Also, I personally couldn't care less about the names used by DDB. I'd rather
stick closer to what SQL has, since people coming from SQL world, and not
people coming from DynamoDB, are our target audience.

> 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.
