> 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.
