[ckan-dev] How to reduce the size of the database "activity" table?

Tue Nov 13 20:49:49 UTC 2018

We should have a CLI command and background job for removing old activity
entries, or collapsing them to 1/day/week/month per dataset.

An option to disable activities entirely would be great for some sites too.

Until we have features like that it should be safe to remove old activity
records directly from the database. I recommend backing up your DB before
any direct modifications, of course.
