https://github.com/apache/spark/pull/35727
> Add factory method getConnection into JDBCDialect.
> --------------------------------------------------
>
> Key: SPARK-38361
> URL: https://issues.apache.org/jira/browse/SPARK-38361
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.3.0
> Reporter: jiaan.geng
> Priority: Major
>
> At present, the parameter of the factory method for obtaining JDBC connection
> is empty because the JDBC URL of some databases is fixed and unique.
> However, for databases such as Clickhouse, connection is related to the shard
> node.
> So I think the parameter form of getconnection: Option[partition] = >
> connection is more general.
