> 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.
