This has several advantages:

  • better concurrency handling: Python is not good with threads (not OS threads)
  • simplifies the code: the grpc-python async API is newer and better than the imperative one. And it makes it easier to handle methods that return Future as asyncio can wrap a Future.
  • opens the path to supporting async read(), async write(), async process(), ... in agents. This will help to integrate with libs that have async APIs (eg. LangChain!)
  • most importantly, will make the life easier to support TopicProducer::write that returns async.

Great stuff.
There is a change related to LangChain that seems unrelated.
I would push it to a separate PR
