It notes in the documentation here that the default delta log retention interval is 30 days - however when I create checkpoints in the delta log to trigger the cleanup - historical records from 30 days aren't removed; i.e. current day checkpoint is at 2023-07-06 and historical records from 2023-04-27 are still remaining.
It's not until I specifically set:
```
ALTER TABLE <table> SET TBLPROPERTIES('delta.logRetentionDuration' = 'interval 30 days')
```
that after creating checkpoints those records from 2023-04-27 are removed as expected. Is there a different default log retention date than what is mentioned here? Or some other hidden process that I am missing?
