Last questions what is the impact to changing the output of
MutationState::getUpdateCount() in the paths where that is used? Its not clear
to me, I tried to follow the change but only went to the writing of the tuple
in one of the iterators...

> Rows deleted count is incorrect for immutable tables with indexes
> -----------------------------------------------------------------
>
> Key: PHOENIX-6218
> URL: https://issues.apache.org/jira/browse/PHOENIX-6218
> Project: Phoenix
> Issue Type: Bug
> Reporter: Tanuj Khurana
> Assignee: Tanuj Khurana
> Priority: Major
>
> For immutable tables if the best query plan for delete uses the data table
> and it has an index, the rows deleted count reported is #(rows
> updated)/#(tables updated) where # of rows updated only includes data table
> rows but the number of tables includes data + index. This reduces the row
> count than the actual rows deleted count.
> The same problem can also happen if the best query plan uses the index table
> and there are more than one index present on the data table. In this case the
> rows updated will include both data table and the index table (one used by
> the query plan) but because there are other indexes also present the #(tables
> updated) will be more and we will get an inaccurate result.
