tracker

State: Design needs to be finalized.

Components

• Client
  • How to access users grouped by job?
  • Use Nats and/ or broker channels for accessing the event data.
  • Use key value store to access data by user ID. -> What about the user's job?
• Worker
  • Load locations from database and generate an event object (like with the broker channel)
  • Store state in key value store for accessing data by user IDs. -> What about the user's job?

What is the state the tracker needs to keeps?

• User's job
• User's on-duty state
• User's unit id -> Centrum UserUnitMapping (settings.proto)
