Amplify datastore is not supporting multitenant

[rpostulart]

The observe is listening to all model data, but it is not possible to only listen to specific data on the model and then apply specific queries and filters on that data.

[rpostulart]

So something like this:

const subscription = DataStore.observe(Post, 123).subscribe(msg => {
console.log(msg.model, msg.opType, msg.element);
});

So we only listen to Posts with id 123

A better requirement description: tell datastore to only get data locally from a certain model with a certain ID

[undefobj]

Could you give more specific information about the use case?

[rpostulart]

I have this schema. The idea is to build an online quiz.
So an admin can create the quiz and send the gamecode to those who want to subscribe. Based on that gamecode they log in and see to quiz data.

But if you look in de localstorage you see all the quiz data and questions

`
type Quiz @model @auth(rules: [{ allow: public, provider: iam }]) {
id: ID!
title: String!
subscribers: [Subscribers] @connection(name: "QuizSubscribers")
seconds: Int!
currentQuestion: String
questionOrder: String
started: Boolean
view: Int
owner: String!
}

type Questions @model @auth(rules: [{ allow: public, provider: iam }]) {
id: ID!
image: String
youtube: String
question: String!
answerOne: String
answerOneCorrect: Boolean
answerTwo: String

answerThree: String

}

}

quiz: Quiz @connection(name: "QuizSubscribers")

}

type Responses @model @auth(rules: [{ allow: public, provider: iam }]) {
id: ID!
quiz: String!
subscriber: String!
question: String!
}
type Languages
@model
@auth(rules: [{ allow: public, provider: iam }])
@key(name: "ByCode", fields: ["type", "code"], queryField: "getLangByCode") {
id: ID!
type: String!
code: String!
}

It is possible to observe one object like so:

const id = '69ddcb63-7e4a-4325-b84d-8592e6dac07b';

const subscription = DataStore.observe(Event, id).subscribe(msg => {
  console.log(msg.model, msg.opType, msg.element);
  onQuery();
});

This also came up here: https://github.com/aws-amplify/amplify-js/issues/5156
I'm adding a note internally to get this added to our docs. Additionally we have a feature we're working on related to the sync and filter functionality so that you can apply finer grained controls to the base query functionality. You can track that here: #5119

[rpostulart]

Ok cool, so then only that data will be locally in the store and not the other data. Thx

[rpostulart]

Is tracked here: #5119

[rpostulart]

When I trigger this on a page load:

const id = "71192197-67f4-4e2d-9569-bbfd67085253"
const subscription = await DataStore.observe(Quiz, id).subscribe(msg => {
console.log(msg.model, msg.opType, msg.element)
})

It still loads all the models and data in the store

[undefobj]

Observing a model is different than loading all the models. If you're looking to just load specific ones that's handled by the feature #5119
