bvolpato opened a new pull request, #28999: URL: https://github.com/apache/beam/pull/28999
The default for fetchSize is 50000 (https://github.com/apache/beam/blob/master/sdks/java/io/jdbc/src/main/java/org/apache/beam/sdk/io/jdbc/JdbcIO.java#L372), which is not even supported by some databases. For example, DB2 limits to 32767 (source: https://knowledge.informatica.com/s/article/000205468?language=en_US). This change will not only allow performance tuning when needed, but will enable usage of partitions on specific databases. -- This is an automated message from the Apache Git Service.
