Hi Thanks for the hints, but I am still very interested about simple working example with combination: sbt-project, scala, csv-file reading and cep processing. I have did not exactly find something like that. It would help me a lot.
It takes lot of time to learn and test many possible code combinations.. Too many “moving” parts.. For example “huge” amount of different “imports” and where I can find how use them and so on ? I did not find strict “reference” guide. For example for readCsvFile(). Or should I look it from code ? By the way what is better to use maven or sbt ? It seems most of examples use maven, but I haven’t got maven to work properly (yet) ..

They also use CEP and basically read also from a file: http://training.data-artisans.com/exercises/CEP.html Regards, Timo Am 2/8/18 um 6:09 PM schrieb Kostas Kloudas: Hi Esa, I think the best place to start is the documentation available at the flink website. Some pointers are the following: CEP documentation: https://ci.apache.org/projects/flink/flink-docs-release-1.4/dev/libs/cep.html Blog post with CEP example: https://data-artisans.com/blog/complex-event-processing-flink-cep-update Cheers, Kostas On Feb 8, 2018, at 4:28 PM, Esa Heikkinen <esa.heikki...@student.tut.fi<mailto:esa.heikki...@student.tut.fi>> wrote: Hi I have cvs-file(s) that contain an event in every row and first column is time stamp of event. Rest of columns are data and “attributes” of event. I’d want to write simple Scala code that: 1) reads data of csv-file 2) converts data of csv-file compatible for CEP 3) sets pattern for CEP 4) Runs CEP 5) writes results Do you have any hints or examples how to do that ? By the way, what kind of time stamp should be in csv-file ?
