What are the AWS Glue partition limits and does it apply to AWS Athena?

Typically you’ll use AWS Glue to create the data sources and tables that Athena will query. You could also create your tables using Athena and then use the tables in AWS Glue. Today the limit for AWS Glue partitions is 10M while Athena’s partition limit is 20K partitions per table. So if you’re using AWS Glue you get more partitions if you’re using the AWS Glue catalog with your Athena deployment. 

When it comes to using Amazon Athena, there are a lot of other limits besides partitions including query, concurrent query, and database limits. Many times AWS Athena users find these limits to hinder SLAs and other business-critical applications.
