Hi,

I'm unable to find any documentation on this config option:
delete_logs_unused_actions_schedule_lowest_interval

Feature was introduced in #13822

I've checked the forums and global.ini.php for help but there is no docs on its usage:

Reading from the code, I get that it is related to how often one should purge data in table log_action.

I've made a PR to add some docs to this, #15492, but also to add a user-definable value for how many rows to analyze in one iterations. Our log_action table contains >100M rows, so pruning data takes a while.
