Redis Implementation Notes

Core Data

Events and Readings

pkg/models/event is stored as a marshalled value using the event id as the key.

Sorted sets are used to track events sorted by most recently added, created timestamp (both relative to all events and scoped to the source device), and the pushed timestamp. Readings are stored similarly in their own sorted sets.

Given

var e Event

and

var e models.Event = models.Event{
  ID: "57ba04a1189b95b8afcdafd7",
  Pushed: 1471806399999,
  Device: "123456789",
  Created: 1464039917100,
  Modified: 1474774741088,
  Origin: 1471806386919,
  Event: "",
  Reading: []Reading{
  Reading {
    ID: "57b9fe08189b95b8afcdafd4",
    Pushed: 0,
    Created: 1471806984866,
    Modified: 1471807130870,
    Origin: 1471806386919,
    Name: "temperature",
    Value: "39"
  },
  Reading {
    ID: "57e745efe4b0ca8e6d7116d7",
    Pushed: 0,
    Created: 1474774511737,
    Modified: 1474774511737,
    Origin: 1471806386919,
    Name: "power",
    Value: "38"
  },
  ...
  }
}

Notification Service

Each of Notification, Subscription, and Transmission objects are stored as a key/value pair where the key is the id of the object. The value is JSON marshalled string.

Given the migration away from BSON ids and toward UUID, all generated ids are UUIDs.

Changes:

  • Add test at internal/pkg/db/test/db_notifications.go
  • Create a separate folder at internal/pkg/db/redis_notification for migrating to master branch
    • Implement db interface function according to internal/support/notifications/interfaces/db.go
Notifications

Notifications are queried by Slug, sender, time, labels, and status. To support those queries a sorted set with the index (e.g. slug) as the score and the value as the key of the notification object in question.

Data Type Key Value Score
Sets Entity ID Entity
Sorted sets "notification" Entity ID 0
Hashes "notification:slug" SlugName and Entity ID
Sorted sets "notification:sender:{sender}" Entity ID 0
Sorted sets "notification:status:{status}" Entity ID 0
Sorted sets "notification:severity:{severity}" Entity ID 0
Sorted sets "notification:created" Entity ID Timestamp
Sorted sets "notification:modified" Entity ID Timestamp

Where LABEL and STATUS are a specific label or status, respectively.

Subscriptions

Subscriptions are queried by Slug, categories, labels, and receiver.

Data Type Key Value Score
Sets Entity ID Entity
Sorted sets "subscription" Entity ID 0
Hashes "subscription:slug" SlugName and Entity ID
Sorted sets "subscription:receiver:{receiver}" Entity ID 0
Sets "subscription🏷{label}" Entity ID
Sets "subscription:category:{category}" Entity ID

Given the migration of EdgeX to UUID from BSON Id, UUID is used for the id in the Redis implementation of the Notification service.

Transmission
Data Type Key Value Score
Sets Entity ID Entity
Sorted sets "transmission" Entity ID 0
Sorted sets "transmission:slug:{slug}" Entity ID Timestamp
Sorted sets "transmission:status:{status}" Entity ID ResendCount
Sorted sets "transmission:resendcount:{resendcount}" Entity ID ResendCount
Sorted sets "transmission:created" Entity ID Timestamp
Sorted sets "transmission:modified" Entity ID Timestamp
