Efficiently move multiple files with dbutils.fs.mv command on abfs storage

[Dean_Lovelace]

As part of my batch processing I archive a large number of small files received from the source system each day using the dbutils.fs.mv command.

This takes hours as dbutils.fs.mv moves the files one at a time.

How can I speed this up?

You can use multithreading.
