----------------------------------
Summary: JDBCAppendTableSink support retry
Key: FLINK-12499
URL: https://issues.apache.org/jira/browse/FLINK-12499
Project: Flink
Issue Type: Improvement
Components: Connectors / JDBC
Reporter: FaxianZhao
JDBCOutputFormat will try to restart the whole job while it catch any
SQLException depend on the Restart Strategy.
So, the network spike is a terrible thing for streaming job which has a jdbc
sink. Sometimes one more try will save it.
Currently, the common case for streaming job delivering messages at-least-once
is to run idempotent queries, retry more than once is acceptable.
