Hi,

Base: Auto-vacuum Internal Data:

Module: This action could be related to the Database Maintenance or System module in Odoo.
Purpose: "Auto-vacuum Internal Data" typically refers to a database maintenance task. Auto-vacuum is a process used to reclaim storage space and optimize the database by removing obsolete data or reclaiming space from deleted records. This schedule action automates the database maintenance process to keep the system running efficiently and prevent unnecessary data bloat.

Hope it helps

Thank you for the above replies. I don't have enough karma to comment individually on the above.

Follow-up - So then this is the same as the internal "Vacuum Verbose" and "Vacuum Full" functionality provided by a PostgreSQL DB?

I also read somewhere (but can't find it now) that "Base: Auto-vacuum internal data" also cleans up the Odoo filestore - deleting unneeded files. Is that true?

Hello Faisal
Base: Auto-vacuum internal data use for Transient model data cleans up automatically by Scheduled Action

It's related to postgres. Here's an explanation of autovacuum from the postegres documentation:

"autovacuum checks for tables that have had a large number of inserted, updated or deleted tuples and then vacuum or analyze the table based on the threshold."
