----------------------------------------------------------------------

2i's are a painpoint during bootstraps and repairs because they are rebuilt after streaming.
Will this be the case for MV's as well?
Ideally, they could be streamed as well. Much less intensive operation both CPU and IO wise.

> 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.
