One of your friends needs to replace the content of a table. He is thinking of deleting the entire directory of the Delta table and creating a new table on the same path. Is this a recommended solution?

Answer options:

A.Yes
B.No

Correct Answer: B 
The given solution is not recommended as: Deleting a directory is not effective. A directory with very large files can consume hours or even days to delete.
You lose all content of the deleted files and it is quite hard to recover if you delete the wrong table.
The directory deletion is not atomic. When you delete the table, a concurrent query reading the table might fail or see a partial table.
