The actual data size of the 2nd table is ≈ 400MB, however due to delta versions it consumes ≈ 40GB. I have added vacuum every hour to the streaming process to keep it even this low. Any suggestions on how I can reduce this storage consumption further? I do not require the versioning. Ideally I could have some way to disable this while retaining the ability to MERGE.</P> Tue, 28 Sep 2021 16:58:48 GMT https://community.databricks.com/t5/data-engineering/how-to-reduce-storage-space-consumed-by-delta-with-many-updates/m-p/14216#M8743 Greg 2021-09-28T16:58:48Z https://community.databricks.com/t5/data-engineering/how-to-reduce-storage-space-consumed-by-delta-with-many-updates/m-p/47857#M28212 <P>Did you already solved this problem?</P> Tue, 03 Oct 2023 12:38:34 GMT https://community.databricks.com/t5/data-engineering/how-to-reduce-storage-space-consumed-by-delta-with-many-updates/m-p/47857#M28212 Jb11 2023-10-03T12:38:34Z
