MILESTONE: Hypermedia Service Bus (HyprBus)

[mlidbom]

Here we link together the work to be done for the milestone as a whole.

• hyprbus: Underlying low latency communication based on NetMQ #37 Underlying low latency communication based on NetMQ
• Traceability by always tracking:
  • CascadeId
  • TriggeredById
• Persistence
  • Topology
    • Command Handler registrations
    • Event handler registrations
    • Endpoint registrations
  • Delivery
    • Outbox
    • Inbox
• Exactly once guarantee
  • Run handlers in transaction
  • Automated retries
  • Future: Manual retries
• Low latency querying
• Ordering / Consistency guarantees
  • In order delivery of events and command (1)
  • Cascade tracking
    • Waiting for cascade completion before executing queries
      • Local endpoint
      • Future: Across endpoints

1. Assuming no permanently failed messages and that you don't enable parallelism for commands/events
