--------------------------------
Summary: Watermark documentation needs to be fixed
Key: FLINK-21931
URL:
https://issues.apache.org/jira/browse/FLINK-21931 Project: Flink
Issue Type: Bug
Components: Documentation, Runtime / Checkpointing
Reporter: Matthias
There's a [ML thread|
http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/pipeline-auto-watermark-interval-vs-setAutoWatermarkInterval-td41891.html] about inconsistencies in the Watermark documentation. The description provided by the docs about setting {{pipeline.auto-watermark-interval}} to {{0}} does not match the actual implementation and the description provided in the JavaDocs of [ExecutionConfig.setAutoWatermarkInterval|
https://ci.apache.org/projects/flink/flink-docs-master/api/java/org/apache/flink/api/common/ExecutionConfig.html#setAutoWatermarkInterval-long-].
I went through the code verifying that the functionality described by the JavaDoc is correct. Setting the parameter to {{0}} disables the automatic watermark generation. The docs need to be updated accordingly.
