-----------------------------------------
Imho, I don't think that this requires a FLIP, it's a simple change/addition.
I created a discussion thread in the list, instead.
> 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
> Priority: Major
>
> 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. (e.g.: CockroachDB)
