not being able to read from Kafka using multiple nodes
Kafka is plenty capable of doing this, by clustering together multiple
consumer instances into a consumer group.
If your topic is sufficiently partitioned, the consumer group can consume the
topic
a good idea.
So in terms of options…. spark streaming, storm, samza, akka and others…
Storm is probably the easiest to pick up, spark streaming / akka may give you
more flexibility and akka would work for CEP.

Spark Streaming useful. Storm also has a join keyword but its semantics are
different.
Also, what do you mean by No Back Pressure ?

Actually the reverse.
Spark Streaming is really a micro batch system where the smallest window is 1/2
a second (500ms).
So for CEP, its not really a good idea.
So in terms of options…. spark streaming, storm, samza, akka and others…
Storm is probably the easiest to pick up, spark streaming
