----------------------------------

             Summary: Driver name is optional for DriverManager.getConnection but a must in JdbcConnectionOptions
                 Key: FLINK-21635
                 URL: https://issues.apache.org/jira/browse/FLINK-21635
             Project: Flink
          Issue Type: Improvement
    Affects Versions: 1.13.0
            Reporter: Kezhu Wang


The most annoying/sad part is that we should change {{getDriverName}} to {{Optional}} according to [code style|https://flink.apache.org/contributing/code-style-and-quality-java.html#java-optional](which is a breaking change in user side since {{JdbcConnectionOptions}} is {{PublicEvolving}}) if we make {{driverName}} optional.
