In general, avoiding rm on Delta tables is a good idea Delta's transaction log can prevent eventual consistency issues in most cases; however, when you delete and recreate a table in a short time, different versions of the transaction log can flicker in and out of existence.

Instead, I'd recommend using the transactional primitives provided by Delta. For example, to overwrite the data in a table, you can:

df. write.format("delta").mode("overwrite").save("/delta/events")
