kafka integration to matlab

I am using Matlab 2019b on Windows 10. I am looking for a way to integrate kafka into matlab? Matlab will be processing real-time data and produce a message to send out through kafka. Any example would be appreciated.

I can easily do this by running a seperate program (python) monitoring a file which matlab produces but I would like to know if there is a way to cleanly integrate matlab and kafka.

Thanks for your input.

Can see a few integration options in this github entry - including a MATLAB integration. There are also Simulink, Code Generation, and Production Server options.

We have released a MATLAB support package that lets you read and write Kafka data as timetables:

https://www.mathworks.com/help/mps/ml_code/deploy-streaming-analytic-function-to-matlab-production-server.html

Despite the name, it does not require MATLAB Production Server, though you can use MATLAB Production Server if you have it.

This doesn't appear to be true. I've tried to use the various functions listed in the example of the link and all return an error requiring the MATLAB Production Server license.

I assume you're seeing something like this:

>> kafkaStream

kafkaStream requires MATLAB Production Server.

Sorry about that confusing error message.

You do have to manually download and install the support package first, per these instructions: https://www.mathworks.com/help/mps/ml_code/streaming-data-framework-for-matlab-production-server-basics.html#mw_94c3f407-4e56-4c47-b52f-37e16700ffcf

You can find the support package here: https://www.mathworks.com/matlabcentral/fileexchange/118415-streaming-data-framework-for-matlab-production-server?s_tid=prof_contriblnk

But it is easier to download and install it via the Add-On Manager, as described in the first link.
