Environment:

mariadb-java-client:3.0.3, Spring Boot 2.6.2


 Description   

It seems like in version 3.0.3 the failover mode "aurora" throws an IllegalArgumentException in the `Configuration.java` class while parsing the `haModeString` in the `HaMode.java` class. There is no enum `aurora` defined.

Using the following Url:
`jdbc:mariadb:aurora://db1-test.cluster-xxxxx.eu-central-1.rds.amazonaws.com/database`
`jdbc:mariadb:aurora://localhost/database`

This seems to match the pattern stated in the about section

yes, I noticed this same thing. for some reason 'aurora' enum is removed from HaMode.class, any idea why?

3.0 is a complete rewrite of the connector. Specific support for aurora has not been implemented in 3.0, since it relies on pipelining. Aurora is not compatible with pipelining.
Issues for Aurora were piling up without the community proposing any PR for them and without access for us to test those modifications, as stated in https://mariadb.com/kb/en/mariadb-connector-j-303-release-notes/#option-removal. 2.x version has a 5 years support, so it won't be a breaking support.
(documentation in knowledge base about aurora has now been updated)
