I want to setup a testsystem with real data. So I copied my kopano production database to the testsystem and removed lots of mails /contacts/ notes , other users and complete stores. After purge-softdelete the attachment directory is nearly empty as well as most of the database tables.
I also set the sync_lifetime to “1” so the sync table is also clean now.
The only table which is still huge is the changes table (>2,2 GB).
What is this table used for and how can I clean it up?
It seams it still contains old entries of deleted stored, mails and users…
Thx in advance
