jiaan.geng updated SPARK-38361:
-------------------------------
Description:
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: Partition = > Connection is
more general.
