If your are working on a non Java/C++/C#/JS application and you need to interact with Infinispan via Hotrod you may be interested in the idea behind the HotSwig[1] project.

Hotswig proposes a framework to build Hotrod client prototypes quickly and for a generic SWIG[2] supported language. As people familiar with C++ and C# Infinispan native clients know, SWIG plays a role in both the projects:

The main goal was to produce for a specific language an almost complete client reusing the C++ core features and the following workflow has been setup to do that:

This approach doesn’t work for the HotSwig goal, mainly because the effort need by the second step is usually not-negligible and prevents the rapid development of prototype in a generic language.

In the HotSwig approach, this limitation is removed moving the adaptation layer from the target language to the C++ side and then letting SWIG generate a ready to use client prototype. So the HotSwig workflow is the following:

At the moment HotSwig is just a proof of concept, but you can try to run it and produce a ready to work Infinispan client for the language you need. Examples are already provided for python, ruby and Octave, but HotSwig should work with all the SWIG supported languages. If you get it to run in your preferred programming language, please share your experience with us.

I’ve listed here[3] some tasks for the roadmap, with the idea to test the flexibility of the framework trying to extend it in different directions. Maybe the idea is good and it can grow up from a PoC to something that can really help devs. You can add you ideas of course.

So if you need to do math against your Infinispan data set why don’t you try the Octave client? Or maybe you want to do analytics with R, or presentation with PHP. Or you just like parenthesis and you want to use Lisp. Or you’re working for the Klingon empire and you must use ylDoghQo'[4]…​ well ok just joking now…​

Thanks for reading!

The first beta version of the Infinispan native python client to connect to the Infinispan Hot Rod servers is available now from Infinispan’s GitHub repository or PyPi. Please check the latest README information to find out more about installation instructions.

So, what’s in it? For this first beta release, we’ve implemented all the operations available in the Hot Rod specification and they’ve been tested with string inputs. This release does not include code to deal with client intelligence superior to 1, so clients cannot receive notifications of cluster changes nor can they locate data in an intelligent manner by applying consistent hash algorithms to the keys. These capabilities, plus further examples such as how to integrate with payloads from Google Protocol Buffers will come in next beta releases.

If you’re looking for code examples for the Infinispan Python client, you can find a very basic one in the README file itself, or check the testsuite within the source package. In next releases we’ll be creating a wiki with more detailed examples.

As always, if you have any doubt please use the user forums and for any bugs or feature requests, please log them via JIRA.

Cheers, Galder
