Re: Attempts at using PyDAOS

That looks much better.  You should be aware that daos will be using a byte-array for the values, so in this case 42 will be a string, not a integer.  It’s likely that you’d want to use pickle/unpickle complex values before storing them.

Thanks, I didn't know about pydaos.Cont and was a bit lost.

I completely missed that section on the deployment documentation, shame on me. I was definetely looking at the wrong places, thanks for pointing that out! I have both the server and the agent running, and thanks to your pointers I have been able to create a key-value from Python and use it.

My success full steps:
