Khokhlov Pavel created FLINK-17488:
--------------------------------------
Summary: JdbcSink has to support setting auto-commit mode of DB
Key: FLINK-17488
URL: https://issues.apache.org/jira/browse/FLINK-17488
Project: Flink
Issue Type: Improvement
Components: Connectors / JDBC
Affects Versions: 1.10.0
Reporter: Khokhlov Pavel
Just played with new
{noformat}
org.apache.flink.api.java.io.jdbc.JdbcSink{noformat}
({{1.11-SNAPSHOT)}}
And batch mode with mysql driver.
Noticed that *JdbcSink* supports only *autoCommit true* and developer cannot
change that behaviour. But it's very important from Transactional and
Performance point of view to support autoCommit {color:#00875a}*false*
{color:#172b4d}and call commit explicitly. ** {color}{color}
** When a connection is created, it is in auto-commit mode. This means that
each individual SQL statement is treated as a transaction and is automatically
committed right after it is executed.
For example Confluent connector disable it by default.
