Let me say first, I'm the Esper project lead.Esper is alive and well and not at
all obsolete. Esper provides event series analysis by providing an
SQL92-standards event processing language (EPL). It allows to express situation
detection logic very concisely, usually much more concisely then any code you'd
need to write and deploy yourself into a streaming container. This is because
EPL has concepts such as joins, subqueries, patterns etc..
By the way, there are so many streaming containers like spark streaming. I
think I could list 20 or more relevant streaming logic containers, all
incompatible to each other, most likely many of these new streaming logic
containers will also be obsolete in the next few years.

Subject: Re: Replacing Esper with Spark Streaming?
obsolete is not the same as dead... we have a few very large tech companies to
prove that point

The big question would be what feature of Esper your are using. Esper is a CEP
solution. I doubt that Spark Streaming can do everything Esper does without any
development. Spark (Streaming) is more a general-purpose platform.

But I would be glad to be proven wrong (which also would implies EsperTech is
dead, which I also doubt...)

Stratio offers a CEP implementation based on Spark Streaming and the Siddhi CEP
engine. I have not used the below, but they may be of some value to you:

Hi,
I'm wondering if anyone has attempted to replace Esper with Spark Streaming or
if anyone thinks Spark Streaming is/isn't a good tool for the (CEP) job?
We are considering Akka or Spark Streaming as possible Esper replacements and
would appreciate any input from people who tried to do that with either of
them. Thanks,Otis
