https://jira.percona.com/browse/PT-2127
Archiving changes some values so that the checksum of the source and destination tables does not give the same values.
By archiving without the --bulk-insert option, the data in the destination table is the same as in the source table, and the checksum of both tables gives the same value.
I have created an issue on Jira 6 days ago with no answer, hopefully I can find some help here.
Thanks everyone!
