James Taylor commented on PHOENIX-2616:
---------------------------------------
There'd be no impact on pre 4.7 clients. There's no need to upgrade the
sequence number as we're not making any structural change. I'll add a defensive
clear of the cache on the server at the end of the upgrade to ensure that the
updated index row will be re-read upon next access.
> Indexes over immutable tables not marked as immutable

> We're not marking indexes as immutable when they're on an immutable table.
> This causes us to do conflict detection when we're building the index which
> is expensive.
