MySQL-Docker unstable, what database to use best with Docker?

Using MySQL-container combined with a Camunda-container seems to be unstable. Parallel connections result in process engine persistence exceptions.

None is preferred, it needs to work smoothly with Camunda. Next to that it needs to be possible to create a database-cluster for scalability, but for this phase 1 instance will do.

Now the different options are:

  • H2
  • MySQL --> unstable
  • Oracle
  • PostgreSQL
  • DB2:
  • MSSQL
  • MariaDB

I would love to hear about the experience of others to be able to make a solid decision.
