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

Only feedback I have on the last few commits is very minor: Not sure we need the clause in
AlterMaterializedViewStatement to check for meta.isCounter() && TTL since we don't
allow counters with MV, do we?

I don't have any other outstanding concerns w/the patch for an alpha commit at this time.
Given the ease and elegance w/which this last round of additions was made I think we're in
a pretty good place to respond to feedback from alpha testing on this.

Edit: [~tjake]: Since you asked nicely: "+1"
:)

> 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.
