Thanks Sameer.
So does that mean that if the events keys are not same we cannot use the CEP
pattern match ? What if events are coming from different sources and need to
be correlated ?

Hi,
You will need to use keyBy operation first to get all the events you need
monitored in a pattern on the same node. Only then can you apply Pattern
because it depends on the order of the events (first, next, followed by). I
even had to make sure that the events were correctly sorted by timestamps to
ensure that the first,next and followed by works correctly.

Hey Folks:
I have a question about CEP processing in Flink - How does flink processing
work when we have multiple partitions in which the events used in the pattern
sequence might be scattered across multiple partitions on multiple nodes ?
Thanks for your insight.
