Description

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.
