According to this article https://mariadb.com/kb/en/mariadb-connector-j-303-release-notes/ Mariadb removed support for aurora in version 3.0.3,
Specific support for aurora has been removed, since Issues were piling up without the community proposing any PR for them and without access for us to test those modifications.
Anyone know if this support is enabled in later versions? We are using 3.0.7 and don't see any issues connecting to aurora db.
