Which Open source CEP shoud I choose for distributed and pipelined processing ; siddhi, Flink , Esper?

Question

I am little bised towards siddhi cep as it has siddhi query language but it uses storm for distributed processing and WSO2 provides an web interface / dashboard to create and deploy applications . I think it will give me less independence to enhance / use some features .

Flink on the other hand seems to be good choice but it requires lot of code to implement even simple logic.

Is there a better option than these , I am Confused

Answer 1

I would do a test...create 10 queries in each system....something like....

  select * from SomeEvent where value = 1
  select * from SomeEvent where value = 2
  ...
  select * from SomeEvent where value = 9
  select * from SomeEvent where value = 10

The idea is to see how easy it is to create the queries, how the API or deploy steps work and how performance changes with the number of queries.
