> Phoenix client can set mutation timestamps for connections with scn. For example, it sets the timestamp for delete mutations. IndexRegionObserver does not check if the timestamp is set for mutations and overwrites them with its current time. While Phoenix does not support setting arbitrary timestamps on the client side for all operations, setting a timestamp for delete mutations is harmless even for tables with indexes. Instead of blindly overwriting mutations timestamps, IndexRegionObserver can leave the determination of which timestamp values are allowed for which operations and sets the timestamp for mutations only when they are not set by Phoenix client.
