Architecture

Melonade are 3 services and clients (they all scalable)

• Process manager

  • Dispatch task to client

  • Validate event from client then save to store

  • Process manager have it's own store that only keep running transaction and current status (Supported Redis and Mongo)

• Time keeper

  • Watch of tasks if timed out, then send event to process manager

  • Delay the dispatched tasks

  • Cron job transaction (Not supported yet)

• Event logger

  • Consume store topic and save to permanent store (Only support Elasticsearch in this time)

• Client (worker)

  • Consume task on it's topic, process then update status back to process manager
