pulsar

hi, try:
```producer.send(message, partition_key=key)```

I agree that the name is not perfect, but it looks that this is actually the `key` from other SDKs

Yes, is anyone willing to add an alias to `key` and deprecate the old argument? :slightly_smiling_face:

Here is the current documentation for the client: <https://pulsar.apache.org/api/python/3.0.x/pulsar.Producer.html#send>.

That might help for other issues.

The docs are generated from annotations on the source code: <https://github.com/apache/pulsar-client-python>

That worked. Thanks a lot for the help. :slightly_smiling_face:
