Readable encoding (i.e. not nippy)

[nivekuil]

Hey, thanks for writing this! Got a simple cron job working nicely and I'm impressed with the API's elegance.

One thing I like about temporal is the ecosystem includes a UI, but it's not very useful here because everything is nippy encoded, which is convenient but not interoperable. Do you have any thoughts on this? e.g. pluggable encoding or remote codec endpoint facilities

Hi Kevin, In theory, you should be able to develop a “Remote Codec” server: https://docs.temporal.io/security#codec-server We haven’t tried as we also encrypt our data in a manner that, by design, won’t work.  I do understand that this would be helpful, though.  Patches welcome!

We've set up a codec server and it definitely works as advertised.

Part 2, which we haven't tried: I believe you can also forward the user's Temporal cluster credentials with the request, which in theory means you can selectively decrypt as well.

I implemented a codec server, leaving it here in case it's useful to anybody.

It would be great as a start, if the Temporal UI submitted workflow params (JSON encoding AFAICT) could be parsed by the Clojure SDK (potentially dispatching on the first byte being {?)

Currently it's passed to Nippy, with a Codec Server decoded payload like:

{
  "metadata": {
    "encoding": "binary/plain"
  },
  "data": {
    "object": {
      "foo": "bar"
    }
  }
}

This would gain us the ability to start simple workflows without having to enqueue them using the Clojure SDK.
