CropDroid Main Device

Raft

As a summary, when -
  - starting a brand new Raft cluster, set join to false and specify all initial
    member node details in the initialMembers map.
  - joining a new node to an existing Raft cluster, set join to true and leave
    the initialMembers map empty. This requires the joining node to have already
    been added as a member node of the Raft cluster.
  - restarting an crashed or stopped node, set join to false and leave the
    initialMembers map to be empty. This applies to both initial member nodes
    and those joined later.

Safety Requirements and Standards

• IPC-2221 Voltage and Spacing Standards
• IEC-60950-1 (2nd edition)

Stores

Config store

The config store is responsible for storing desired device configurations and/or settings.

State Store

The state store is responsible for keeping a single "record" for a device that indicates it's current metric and channel values.

Device Store

The device store is responsible for keeping historical data for a device - that is, many metric and channel values over time, used for analytics and reporting.

Golang channels

The following golang channels are created for each farm

1. Farm state gc ticker
2. Device state gc ticker
3. farm.WatchFarmStateChange
4. farm.WatchFarmConfigChange
5. farm.WatchDeviceStateChange

Known Bugs

• Not getting push notifications
• Enable/disable toggles wrong sensor
• Conditions not ordered by time
• Workflow steps out of order
• Roles not loading
