TODO

  • Test coverage is non-existent

  • Health checks

  • Shutdown hooks

  • hollywood-cli dev should check if cargo watch is installed

  • Add Msg Id

  • Run options:

    • Max queue size

  • Uber runtime across multiple actors

    • Process launcher
    • Config to define system
    • Configure HOLLYWOOD_* variables
    • RunOptions::from_env
    • Client::from_env

  • Client request should define one type which is the same for input and output

  • Mailbox that is specific for Actor version + Msg version (so we don't have to pass type hints with mailbox calls).

    mailbox::actor1_v1::msg1_v1_0::new(...)
mailbox::actor1_v1::msg1_v1_1::new(...)
mailbox::actor2_v1::msg2_v1_0::new(...)
mailbox::actor2_v1::msg2_v1_1::new(...)

Maybe we could add this to the Hollywood macro so it produces
a mod for the actor version and msg version.

  • Client calls should configure timeouts

    • - hollywood client request_timeout
    • - nats client initialize: max number of attempts to retry connecting to nats

  • Nats clients should retry connecting if nats server goes away

  • Agent configure Actor as a pubsub subscriber

  • Client should be able to publish messages to a subject

  • Versioned Actor messages

    • Dispatch trait + macro
    • rework Client and make Mailbox wrapper

  • Examples: redis client should support retries

  • Nats: support JetStream as a Queue?

Maybe

  • Where does Docker fit in?
  • Swap serde_json w/ protobuf for HollywoodMsg's
  • Worker pools - We'd need to change how Actors are instantiated (Use Arc, etc?) - Not sure this is worth it for now
  • Metrics: tokio metrics or some other implementation
