Recommendations for translating Whisper to Java?

Asked by greg

I was just looking into using rrd4j but got depressed about the problem that Whisper solves but RRD has, namely the regularity of updates...

I'd like to use Whisper but need it in a Java runtime and have little Python expertise.

Any tips on the design of Whisper and what would not translate over to Java well?

thanks!

The easiest route is probably just using jython like Aseem suggests, but if that is not an option for you then whisper is not a very complex piece of code to re-write. It's only about 500 lines of python, so it would probably only take about 1,500 lines of java to do the same (for me at least, I'm no java pro). The code does not have a ton of comments but I tried to write it as intuitively as possible using descriptive variable names and such. If you do try to port it let me know if you run into any issues and I'd be glad to help.

I'm running into the same problems, so I'm going to be attempting to make the port to Java. The project will probably be hosted on my github http://github.com/ezephyr/jwhisper

Neat! Check out this if you haven't seen: http://graphite.readthedocs.org/en/0.9.x/whisper.html

If you're only doing a read-only port that should be just about all you need. If you're going to support writing, the propagation is a bit funky as well as the logic for update_many (which is essential for sane write performance). Send a note out if you need help understanding it.

It turns out that the project at work that I was going to use jwhisper for went in a totally different direction, so I haven't had any motivation for working on it.

Though I've started working with clojure a lot lately, so I may decide to try and start a port to clojure (which would then be easy to make available to a java program as a jar).

But I'd go with whisper4j, since there's actually code there (working or not I don't know...)

Can you help with this problem?
