Re: Flink Python streaming


to use libraries you have to supply them when submitting the job as described below. Additional directories/files will be placed in the same directory as your script on each TM.


Note that libraries that make use of C-extensions will probably not work.

AFAIK it's not that easy. Flink's Python support is based on Jython which translates Python code into JVM byte code. Therefore, native libs are not supported.

Chesnay (in CC) knows the details here.

Hi Bing,

I'm not familiar with python programming. I guess we can simply import libraries in the python script. A example can be found here[1].
Hope this helps.

Best, Hequn

I'm wondering how I can add dependencies for third party and custom libraries to be executed in Flink for python streaming? 

Thank you,
