------------------------------------
Summary: Add a upsert table sink for JDBC
Key: FLINK-12956
URL: https://issues.apache.org/jira/browse/FLINK-12956
Project: Flink
Issue Type: New Feature
Components: Connectors / JDBC
Reporter: Jingsong Lee
Assignee: Jingsong Lee
Now we just support append JDBC sink, this is very limited. Consider a simple
wordCount, we need insert/update the sink with primary keys.
So we need to support upsert JDBC sink.
1.Introduce a AbstractJdbcOutputFormat to extract some common method from
JDBCOutputFormat. Introduce a UpsertJDBCOutputFormat which extends
AbstractJdbcOutputFormat.
2.Introduce UpsertJdbcTableSink.
