I understand that pt-table-checksum can do checksum compares between a master's DB and a slave's DB easily.
However, let's say your master has two slaves replicating from it for the same DB, i.e. Slave 1 and Slave 2.
Is there a way to use pt-table-checksum to run a direct checksum comparison between Slave 1 and Slave 2's databases? In this scenario, I am not as concerned with comparing any of the slaves with the master itself.
