When should I run the FSCK REPAIR command on my Delta table

[brickster_2018]

Is it a good practice to run the FSCK REPAIR command on a regular basis? I have Optimize and VACUUM commands scheduled to run every day.

Unlike OPTIMIZE and VACUUM, FSCK REPAIR is not an operational command that has to be executed on a regular basis. FSCK REPAIR is useful to repair the Delta metadata and remove the reference of the files from the metadata that are no longer accessible. This can happen when these files have been manually deleted.
