James Taylor commented on PHOENIX-3858:
---------------------------------------

[~mujtabachohan] can you test with mutable tables for writes to confirm the 2x cost is due to the lose of this optimization?

> While preparing index mutations we are are scanning data region for index maintenance which is not required in case of immutable rows. This optimisation is very helpful for local indexes which got removed in the recent changes.
