------------------------------------
Summary: Allow for negative initial watermark value
Key: SPARK-40942
URL: https://issues.apache.org/jira/browse/SPARK-40942
Project: Spark
Issue Type: Improvement
Components: Structured Streaming
Affects Versions: 3.4.0
Reporter: Alex Balikov
Currently at Spark SS pipeline start, the initial watermark value is 0 and thus
records with event time 0 will be filtered out as late due to the requirement
of event time > watermark. This is untypical scenario as event 0 is probably
synthetic, but still probably should be handled.
