Pt-archiver not using --columns listed when index is defined manually

Hello,

We’re currently trying to utilize pt-archiver to delete old records from a MySQL 5.7 AWS Aurora database, however we’re not able to specify both the index and columns at the same time, it seems the utility ignores the --columns options.

Output from --dry-run:

[root@~]# pt-archiver --source h=dns,P=3306,u=user,p=pwd,D=db,t=attempt,i=IDX_18EC02668B8E8428 --purge --where "created_at between '2018-07-26 00:00:00.000' and '2018-07-26 01:00:00.000'" --limit 1000 --txn-size 1000 --bulk-delete --low-priority-delete --no-check-charset --no-safe-auto-increment --columns id,created_at --dry-run

Version:

[root@~]# pt-archiver --version
pt-archiver 3.3.1

Any thoughts?

Thank you.

Hello again,

Would anyone have an idea why this is happening? Is it possible this is a bug in the archiver utility?

We’re currently running a DAG that is purging billions of records from this table, and since we don’t need to archive this data anywhere selecting all the columns is inefficient, and the load in the DB could probably be reduced.

Any help is appreciated.

Thank you.

Renato.
