Hi Kostas,
I noticed that you commented on FLINK-7549 and FLINK-7606. I was
monitoring both these JIRAs.
I was always using time characteristic as event time like you had suggested
but I continue to see patterns not getting detected. Could you help shed
more light on this ? I had shared some cod
Hi Ajay,
I will definitely have a look to see what is happening.
And I will keep you posted.
Thanks for investigating it.

Hi Kostas,

Hi Ajay,
After reading all the data from your source, could you somehow tell your
sources to send
a watermark of Long.MaxValue (or a high value)??
I am asking this, just to see if the problem is that the data is simply
buffered inside Flink because
there is a problem with the timestamps and th
Hi Kostas,
Thank you for reaching out and for the suggestions. Here are the results
1. Using an env parallelism of 1 performed similar with the additional
problem that there was significant lag in the kafka topic
2. I removed the additional keyBy(0) but that did not change anything
3. I also trie
Hi Ajay,
I will look a bit more on the issue.
But in the meantime, could you run your job with parallelism of 1, to see if
the results are the expected?
Also could you change the pattern, for example check only for the start, to see
if all keys pass through.
As for the code, you apply keyBy(0
Hi,
I've been only working with flink for the past 2 weeks on a project and am
trying using the CEP library on sensor data. I am using flink version
1.3.2. Flink has a kafka source. I am using KafkaSource9. I am running
Flink on a 3 node AWS cluster with 8G of RAM running Ubuntu 16.04. From the
