Which database has the highest performance

Good morning guys.

I’m new with temporal and I understood that temporal needs a database (MySql, PostGreSQL or Cassandra) to store the state of the workflow, store metadata of the namespaces in the cluster, etc… Is there any recommendation to use between MySQL or Postgre with regarding performance?

I am predicting the use of 100,000 workflows a day, with the possibility of having 20% of these flows occurring in parallel.

If you have any reference or benchmark that can help I would be very grateful.
