Complex Record Subscriptions

In the following examples, we have a table called students, which contains fields and relations like id, firstName, email, age.

Subscriptions using filters

You can subscribe to individual and related records being created, updated, and deleted using Archie Core’s auto-generated GraphQL subscriptiong operation.
