pt-table-checksum in master-master environments
Asked by
Volans
I would like to know if it is safe (from the replication point of view) to run pt-table-checksum toolkit in environments with a master-master MySQL configuration with slaves like this one:
A=B
| |
C D
Masters:
* A is slave of B
* B is slave of A
Slaves:
* C is slave of A
* D is slave of B
The documentation do not discuss about such a configuration, unlike the pt-table-sync documentation for example.
In addition to the safety of the tool, I would like also to know if running pt-table-checksum on server A, automatically make the ckecksums on all the other servers.
Thank you in advance
