James Taylor commented on PHOENIX-3128:
---------------------------------------
The idea with that code is to not send local immutable index updates over the
wire, but generate them on the server side. Is that not what you're seeing?

>
> Upsert to a table with a local immutable index is supposed to be more
> efficient than to a table with a local mutable index, but it's actually
> slower (in our environment by 30%) due to extraneous operations involved.
> The problem is twofold:
> 1. Client unnecessarily prepares and sends index update.
> 2. Index cleanup is done regardless of the immutability of the table.
