Sliding Windows

[Paulo Suzart]

Hi Guys,

I was looking for a very simple stream processing lib. We have some in clojure (lamina, meltdown, esper, eep).

The simplest one was clojure werkz eep, but they don't provide sliding windows. I ender up writing this: http://paulosuzart.github.io/blog/2014/04/27/sliding-window-events-with-clojure/

And publishing this very small implementation using meltdown. https://github.com/paulosuzart/sw . It is enough for a very simple use case I have to deal. If anyone knows any other sliding window impl please share.

Regards

Riemann seems to have one:

We've had lots of luck with Narrator: https://github.com/ztellman/narrator

It's got loads of powerful features, including realtime & batch mode, integration with core.async and lamina, windows, functions, and recursive analyses.

Ow, exactly what I was looking for. Thanks a lot

Since you already like clojurewerkz EEP, why not just add a time-sliding window to it?
