Bowen Li updated FLINK-16811:
-----------------------------
Parent: FLINK-15350
Issue Type: Sub-task (was: Improvement)
> introduce JDBCRowConverter
> --------------------------
>
> Key: FLINK-16811
> URL: https://issues.apache.org/jira/browse/FLINK-16811
> Project: Flink
> Issue Type: Sub-task
> Components: Connectors / JDBC
> Reporter: Bowen Li
> Assignee: Bowen Li
> Priority: Major
> Fix For: 1.11.0
>
>
> currently when JDBCInputFormat converts a JDBC result set row to Flink Row,
> it doesn't check the type returned from jdbc result set. Problem is that
> object from jdbc result set doesn't always match the corresponding type in
> relational db. E.g. a short column in Postgres actually returns a Integer via
> jdbc. And such mismatch can be db-dependent.
>
> Thus, we introduce JDBCRowConverter interface to convert a db specific row
> from jdbc to Flink row. Dbs should implement their own row converters.
