Marios Trivyzas created FLINK-31553: ---------------------------------------
Summary: Choose Catalog, non-url based Key: FLINK-31553 URL: https://issues.apache.org/jira/browse/FLINK-31553 Project: Flink Issue Type: Improvement Components: Connectors / JDBC Reporter: Marios Trivyzas Currently. the {*}Catalog{*}{*}/Dialect{*} (etc.) is chosen automatically based on the URL provided. This takes place in {*}{color:#000000}JdbcDialectFactory{color}#load{*}, using the: {*}{color:#000000}JdbcDialectFactory{color}#acceptsURL{*}, so for a URL *jdbc:postgresql://...* the PostgresCatalog/Dialect is used. *CrateDB* used the same driver and URL but needs it's own Catalog/Dialect (etc.) as it has it's own stack of internal tables, type sytem, etc. (see https://issues.apache.org/jira/browse/FLINK-31551) So if a user wants to use *CrateDB,* currently, needs to use the legacy CrateDB driver which uses the jdbc:crate://... url. Ideally, there should be another way, not only url based, that allows the user to use a given url, but choose the dialect manually. It could be some parameter on the catalog definition or even a special URL parameter like *?dialect=CrateDB* or so. Other DBs that use implement the PostgreSQL wire protocol and are compatible with the PostgreSQL JDBC driver, but need their own Catalog/Dialect etc. would benefit from this.
