Support multi-tenant

[kenklin]

Describe the feature you'd like to request

Amplify DataStore with Multi-tenancy

As a SaaS software company, we have customers whose data not only needs to be protected from each other, but also need finer access for different employees within the company. Furthermore, our professional motorsports team customers need software that is local-first, so that their data may be manipulated, viewed, and analyzed by our software in a standalone fashion on their laptops (Electron) and mobile devices (and web), later to be backed up to the cloud and synced with other team engineers. We work with SRO Motorsports, which AWS is a title sponsor.

At first glance, Amplify DataStore's selective sync with AppSync and DynamoDb seemed like a promising technology to implement local-first data with cloud sync, but we then realized in our discussion with AWS staff on Discord that multi-tenancy was not easily provided out of the box.

Describe the solution you'd like

Multi-tenant local-first data base that can sync with cloud, running on

• Windows & Mac Desktops (Electron),
• PWA,
• Mobile

We'd like to see a complete front-to-back multi-tenant example, from a customer user's authentication in an Amplify app, to DataStore read/write, AppSync, to DynamoDb.

Describe alternatives you've considered

We've read about several including those mentioned here. We are currently experimenting with Couchbase Lite and may also try Firebase.

I support this request. Also looking for a multi-tenancy solution for users to sign in based on email domain so compant data remains separate only sharing the UI.

Hey @kenklin 👋 thanks for raising this! The multi-tenant request appears to be a duplicate of a few other issues around the topic:

• @auth Combining Owner/Groups rules for Multi-Tenant Apps #449
• How to deploy a fine grained authorization model? #281
• Multi-tenant (organisation) support for GQL APIs #949
• True multi-tenant support and modelling with @auth #452
• Datastore efficient query and subscription for multi tenant app #335

I'm going to mark this as a documentation feature-request to look into adding an example like this!
