-The relational JDBC metastore currently relies on a Quarkus-managed datasource and supports only Postgres and H2—similar to EclipseLink. However, we only provide documentation for using it with Postgres. In future releases of Apache Polaris, we plan to extend support to additional RDBMS datasources such as MySQL and MariaDB. These are not currently supported due to differences in schema requirements and error handling conventions.
+The Relational JDBC metastore currently relies on a Quarkus-managed datasource and supports only PostgreSQL and H2 databases. This limitation is similar to that of EclipseLink, primarily due to underlying schema differences. At this time, official documentation is provided exclusively for usage with PostgreSQL.
