First of all thanks Jan for implementing the first batch of commands manipulating XDB files on https://jira.mariadb.org/browse/MDEV-7472
I would like to follow up on the last comments, and open this new request to implement the remaining user commands:
- RESET CHANGED_PAGE_BITMAPS
- PURGE CHANGED_PAGE_BITMAPS BEFORE <lsn>
I am especially interested in the last one, as when we enable innodb_track_changed_pages feature, it can fill up disk space quickly on busy servers. It's a good practice to purge the xdb files up to LSN from last successful backup.
Thanks in advance,
