pt-table-checksum: Continuing and Resuming

We have several tables that have an auto-inc PK with data that never changes once inserted. We would only need to run pt-t-c once for the entire table and then subsequent runs would only need to check those rows that have been added since last run.

The ‘–resume’ flag is only for those cases where pt-t-c aborted in the middle (due to mysql error or user-cancel).

How can I tell pt-t-c to “resume” or “continue” checking a table with new data? Would I have to script something to pull out the last boundary and run pt-t-c with --where and that chunk boundary?

i don’t know script for that. And with the --retry option ?
