Hi Esa,

the SQL/CEP integration might be part of Flink 1.7. The discussion hasjust been started again [1].


Regards,
Timo

There was one good example of pattern query in the paper made by SASE+language (in attachment).

Could you easily say how to do that FlickCEP with Scala ? Or is itpossible ?

That SQL and CEP would also be very interesting, but when it is readyto use ?

Hi Esa,

I think the core implementation pattern is still based that paper,there is a package named "nfa"[1] contains the main thought.

The latest CEP module added more features and enhanced the old versio.What's more, there is a FLIP-20 which has been accepted, it describedhow to integrate with SQL and CEP.[2]


I think there is no newer paper related to current Flink CEP.

Thanks, vino.

    Hi

    Thank you. This was very good paper for me J

    How much current FlinkCEP works like this (the paper was written
    2008) ?

    Are there exist newer papers related to current FlinkCEP ?

    You are right Vino,

    the initial implementation was based on the above mentioned paper.

    Cheers,

        Hi Esa,

        AFAIK, the earlier Flink CEP refers to the Paper 《Efficient
        Pattern Matching over Event Streams》[1]. Flink absorbed  two
        major idea from this paper:

        1. NFA-b model on event stream

        2. a shared versioned match buffer which is a optimized data
        structure

        To Till and Chesnay:

        Did I missed anything when as time goes on and the development
        of Flink? If yes, please give your additional remarks.

            Hi

            I don’t know this the correct forum to ask, but are there
            exist some good scientific papers about FlinkCEP (Complex
            Event Processing) ?

            I know Flink is based to Stratosphere, but how is it
            FlinkCEP ?
