> Currently, bootstrap dump shall lead to data loss when any rename happens while dump in progress. 
> *Scenario:*
> - Fetch table names (T1 and T2)
> - Dump table T1
> - Rename table T2 to T3 generates RENAME event
> - Dump table T2 is noop as table doesn’t exist.
> - In target after load, it only have T1.
> - Apply RENAME event will fail as T2 doesn’t exist in target.
> This feature can be supported in next phase development as it need proper design to keep track of renamed tables/partitions. 
> So, for time being, we shall disable rename operations when bootstrap dump in progress to avoid any inconsistent state.
