--------------------------------
Summary: introduce JDBCRowConverter
Key: FLINK-16811
URL: https://issues.apache.org/jira/browse/FLINK-16811
Project: Flink
Issue Type: Improvement
Components: Connectors / JDBC
Reporter: Bowen Li
Assignee: Bowen Li
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.
