we use checksum’s to run for a couple of hours everyday during non peak hours and kill it after 2 hours. Next day it will run again for 2 hours and get killed. In this scenario, the --resume option from ( percona-toolkit/2.0/pt-table-checksum) is useful to let the every second day checksum’s continue from the last day’s last chuck where it killed.
But the same option --resume stops the checksum process to run after one complete run on the data set. It will not start automatically to run the checksum’s from the first chunk again of the full dataset for the second time.
Is there an option to let the checksum’s continue forever on the same dataset repeatedly as the data gets updated on master and replicates to slave regularly.
