[jira] [Created] (FLINK-21820) JDBC connector shouldn't read all
rows in per statement by default
Leonard Xu created FLINK-21820:
----------------------------------
Summary: JDBC connector shouldn't read all rows in per statement by default
Key: FLINK-21820
URL: https://issues.apache.org/jira/browse/FLINK-21820
Project: Flink
Issue Type: Improvement
Components: Connectors / JDBC
Reporter: Leonard Xu
The default value for JDBC option 'scan.fetch-size' is 0 which means read all rows in statement, this may lead to OOM or IO timeout.
We'd better set a reasonable value as default value.
