AWS Glue Crawler creating temp_tables in Athena

Question

I have a set up with a few crawlers crawling a few buckets and generating tables within Glue that are then able to be queried from the Athena query engine.

I have noticed recently that a lot of tables have been popping up, none located in the buckets I am crawling and all look like some system generated tables

temp_table_*

There appear to be over 10 created every day, and when I look at the details of them they are generated from the system query results s3://aws-athena-query-results-*

Is there a reason these are created? Do I have to manually clean them up? Is there a way to stop them being generated, or ignore them ?

They are cluttering the ability to see the tables that matter in Athena.

Thanks in advance for any assistance.
