Prerequisites:

• Java 11
• Maven 3.2+
• Docker
• Redis + Modules 6.0.1 or greater

1. Start the Docker Compose application:

   cd redi2hack
   docker-compose up
   

2. Run the Spring Boot app to build the application.

   ./mvnw clean -Dspring-boot.run.profiles=local spring-boot:run
   

3. Goto: http:https://localhost:8080/playground

GraphQL is supported using Spring Boot which is backed by Redis enterprise data store.

The data flows from left to right - from GraphQL->Redis and Redis->GraphQL.

• createCustomer, updateCustomer, and deleteCustomer GraphQL mutations use Redis hash and stream data to store the state and push the events.

• subscribeEvents (GraphQL subscription) uses Redis Stream to fetch all customer events or the latest customer events.

• searchCustomers GraphQL query uses RediSearch to search customers.

• customers and findCustomer use Redis Hash to find the all or a particular customer.

This project shows how to use GraphQL Subscription to push event data from the server using Redis Streams and support real-time search using RediSearch.

• RediStreams: to capture all the customer events
• RediSearch: to support search customer capabilities
• RediHash: to store customer data
• GraphQL:
  • Subscription: to push real time customer events
  • Mutation: to create/update/delete the customer state
  • Query: to query/search customer information
