It comes as part of storage optimization that allows&nbsp; to delete, update, merge operations to mark existing rows as removed or changed without rewriting the whole Parquet file. This helps in optimize performance of partitioned tables by managing row-level change more efficiently.&nbsp;</P> Tue, 17 Jun 2025 17:21:54 GMT paolajara 2025-06-17T17:21:54Z https://community.databricks.com/t5/data-engineering/deletion-vectors-on-partioned-tables/m-p/121955#M46608 <P>Are Deletion Vectors supported for partitioned delta tables in Databricks?</P> Tue, 17 Jun 2025 08:51:20 GMT https://community.databricks.com/t5/data-engineering/deletion-vectors-on-partioned-tables/m-p/121955#M46608 pooja_bhumandla 2025-06-17T08:51:20Z https://community.databricks.com/t5/data-engineering/deletion-vectors-on-partioned-tables/m-p/122022#M46628 <P>Hi&nbsp;<a href="https://community.databricks.com/t5/user/viewprofilepage/user-id/170125">@pooja_bhumandla</a>&nbsp;, Yes, deletion vectors are supported for partitioned delta tables in Databricks.
