Excellent for giving such a clear understanding of the detailed concepts of Databricks

Excellent. I am referring to all your videos, very nice and detailed explanation of concepts. Thank you.

[@shalushalini3392]

Thank You For the details, I have 2 question related to the same. 1. What if the table is very old and no operation has been done recently, Will VACCUM delete all the version files except 1 ? 2. While doing truncate table will it delete older data version and If VACCUM required if we are doing truncate or drop reload the tables

Very good.

[@saikumarjakki3802]

if the vaccum cmd only del the data file and not del the transaction logs then when reading the file using deltalog i will through error for that particular version and cause issue by default it will take the latest version but what if we want read all the version then it will cause issue right . how to del the transaction logs as well for that particular version . can u pls explain it.

Outstanding!!👋

After deleting the version we can't restore the deleted version file ?? My question was what is vacuum start version & Vacuum end Version. we can recover deleted version file using the vacuum versions???

This video is good

Thanks for the clear explanation. But can we restore the deleted files after vacuum command?

[@vijaychandra8027]

Once we perform vacuum command, the part file cannot be restored back as it will be permanently deleted from delta lake.

If I need to delete a file, I use the restore table and never delete using dbutils.fs.rm(path), right?
