This addon adds a hook to your Ember Data Adapter (and all adapters extended from DS.Adapter) to generate the id of each record you create on the client-side. This hook can be deactivated from your config (see Deactivate the "auto UUID" feature).
The created ids are v4 UUIDs which are random "enough", quoting wikipedia:
the annual risk of a given person being hit by a meteorite is estimated to be one chance in 17 billion, which means the probability is about 0.00000000006 (6 × 10−11), equivalent to the odds of creating a few tens of trillions of UUIDs in a year and having one duplicate. In other words, only after generating 1 billion UUIDs every second for the next 100 years, the probability of creating just one duplicate would be about 50%.

ember install ember-cli-uuid
This Ember CLI module is intended for use with Ember Data. Once you install it (and the blueprint is applied) your ember data models will get a new behaviour when being created on the client-side. When creating a model like that :
Your model will get a v4 (random) UUID as his primary key :
id: 'b4301bcb-a687-4f91-86c8-8b9241f6e6bc'title: 'My post'
You might need to turn off the auto generation of UUIDs on your Ember Data models. To achieve that, you will need to edit your
config/environment.js file like this :
const ENV =// ... others config vars'ember-cli-uuid':defaultUUID: false;
You can also (if you need a UUID v4 somewhere in your app) use it like that :
