ChannelCodec is the interface for encoding/decoding operations for messages that can fail on both ways.

Note that this is not a typeclass and it is not used in implicit scope and there are no instances of it.

EventChannel implements a pubsub topology for events.

In this topology, peers publish or subscribe to certain communication channels (logical streams of data). In this topology every consumer gets a copy of data, which is in contrast to previous topologies where a single piece of data is routed to exactly one peer. This topology guarantees at least one delivery of messages.

RPCChannel implements an async RPC communication channel topology.

In this topology, each server has its own endpoint, where clients can send methods to, server then can decide to response to sender's address, ignore the request, or reject it. Clients can then consume responses, and mark them as processed. This topology models an point to point communication, with at least one delivery semantics, so your processing MUST be idempotent and async, as both responses and requests might be received several times, and with any ordering.

WorkPoolChannel implements a work pool topology.

In this topology, one or more peers produce jobs, and one or more workers compete over processing those jobs. This topology handles workers fail over, so if a worker fails, its jobs will be routed to another worker. However this topology can't guarantee any ordering of messages by definition.
