[jira] [Updated] (FLINK-17294) Using "DataSource" instead of "DriverManager" to get connection in JDBC connector

     [ https://issues.apache.org/jira/browse/FLINK-17294?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Lijie Wang updated FLINK-17294:
-------------------------------
    Description: 
I noticed that JDBC connector using DriverManager to get connection, but DataSource is encouraged now.  We should using  DataSource  instead of DriverManager.

About the DriverManager vs DataSource, see https://stackoverflow.com/questions/15198319/why-do-we-use-a-datasource-instead-of-a-drivermanager.

Some implementations of DataSource maybe we can use : alibaba durid, apache dhcp

And we should introduce connection pool to get more performance.
