I think siddhi is a fairly matured CEP library. I am thinking it should co-exist with existing CEP library. My thinking is we should be able to use Siddhi QL/ Siddhi Patterns on top of flink data streams. This can co-exist naturally with existing Java / Scala based Flink CEP Library. I am still reading up on Flink internals – but at high level I am thinking about a new Flink operator on DataStream for this. Thoughts ?

How mature is it; how is the community? How does it compare to the Flink's CEP library? How should this integration look like? Are you proposing to replace the current CEP library, or will they co-exist with different use-cases for each? If we used Siddhi in Flink, how exactly would Flink's runtime be involved in the processing? Regards, Chesnay On 28.08.2016 23:21, Aparup Banerjee (apbanerj) wrote: Sorry for the semantic difference.
