VACUUM operations on existing table after enabling predictive optimization

[ShivangiB1]

Hey Team, 

I have a table with files deleted 7 days before, but predictive optimization was not enabled.Today have enabled predictive optimization, how much time will it take to perform vaccum on existing data.

Once predictive optimization is enabled and the table is in use, VACUUM will be automatically triggered 7 days later.

But if a table with predictive optimization enabled has no active usage, the optimization process does not detect the table or its previously deleted data.
