Flink CEP support pattern match involving fields of previous events

[Spico Florin]

Hello!

I would like to ask you if you have added the support for CEP for  match involving fields of previous events, the same that was asked here:

"However it would be great to create Pattern out of a capability like: .where(second_evt->evt.getTemperature() == first_evt->evt.getTemperature()"

and 

https://stackoverflow.com/questions/38770195/apache-flink-cep-detect-same-events

If, yes which version support this feature and what is the API syntax?

Thanks.

Hi Florin,

This feature is supported with IterativeCondition since 1.3.0. For questions about API and what features are supported in general please always have a look into documentation[1] first.

Best,

Dawid
