Aggregate objects

[ironfroggy]

Provide helpers to implement aggregate objects safely updated from multiple devices

Use Cases:

• Distributed Counters
• Sets and Mappings
• Distributed Flags
• Distributed Sequences

These will be helpers built on top of persisted Views, to provide easy ways to modify device-data and sync with other devices, even if they're modifying the same structures. The devices will modify their local contributions, and the view will generate the aggregate.

These will be defined as stores, with an extension. The extension will

• Inject the view into the schema, hidden
• Add specific read and write methods

Examples

• s.put("bob", {coffee: 0});
  s.incr("bob.coffee")
  s.get("bob") -> {coffee: 1}
