databricks - delta vacuum didn't clean older data - Stack Overflow

admin2025-04-17  2

I executed vacuum on a delta table on Jan 31 : retain 450 hours. After the vacuum, I can still access Version 22 which falls out of the retention period. So, why didn't the vacuum clean out that version? I was expecting all data prior to Jan31 - 450 hours to be removed when the vacuum runs.
