before/after do they refer to processing time? about flink-spector

[lofifnc]

Hi,
The before and after notation will produce a StreamingSource which will emit records with timestamps and watermarks based on that description. Internally the time semantic of the streaming environment is set to EventTime. If I'm not mistaken the timestamp extractor will ignore the watermarks which flink-spector produces and attach new timestamps and watermarks.

Is the last value inserted into the first window? Or does it show up in a second window? If it is aggregated in a second window this is the normal behavior of the tests. Based on your input it the test should produce two tumbling windows. The first one contains the first three records and the second one the last record.

The ability to work with processing time would help with testing a number of different scenarios.
But as of yet I haven't found a good way of manipulating processing time or syncing it precisely with the incoming records.

Best Regards, Alex

I'm going to close this issue as it is in some way a duplicate of issue #29.
