LakeShen created FLINK-16681:
--------------------------------
Summary: Jdbc JDBCOutputFormat and JDBCLookupFunction
PreparedStatement loss connection, if long time not records to write.
Key: FLINK-16681
URL: https://issues.apache.org/jira/browse/FLINK-16681
Project: Flink
Issue Type: Improvement
Reporter: LakeShen
Fix For: 1.10.2
In my thought, jdbc connector is the one of most frequently used connector in
flink . But maybe there is a problem for jdbc connector. For example, if
there are no records to write or join with dim table for a long time , the
exception will throw like this :
java.sql.SQLException: No operations allowed after statement closed
Because there are long time no records to write , the PreparedStatement loss
the connection.
If there is no other jira to solve this problem , can you assign this jira to
me , I will try my best to solve it , thank you .
