-----------------------------------
Summary: Add support for ignore abnormal watermark
Key: FLINK-21120
URL: https://issues.apache.org/jira/browse/FLINK-21120
Project: Flink
Issue Type: Improvement
Components: API / DataStream
Affects Versions: 1.11.1, 1.12.0
Reporter: zlzhang0122
When using eventTime and extract watermark from element timestamp to generate
BoundedOutOfOrderness waternark, if one of the element timestamp is
abnormal(the timestamp is very big, for example Integer.MAX_VALUE), then the
watermark became very big too, and then the normal element timestamp can not
trigger the window bellow any more. I think maybe there can provide a option to
just ignore the abnormal element timestamp or generate a normal watermark base
on the current processTime.
