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.
