             Summary: Allow more dynamic splitter on JdbcSource
                 Key: FLINK-38733
                 URL: https://issues.apache.org/jira/browse/FLINK-38733
             Project: Flink
          Issue Type: New Feature
          Components: Connectors / JDBC
            Reporter: João Boto


Today in JdbcSource we need to provide the sqlTemplate and the sqlParameters 
that will be used to do multiple queries to database, normally this parameters 
would be queried previous the job to get the the min and max values (as example 
as full snapshot of a table) to then calculate all the sqlParameters needed ..

The objective of this is to have a SplitterEnumerator that allow the user to 
implement this in the source, having a more dynamic way to use the JdbcSource..
