Hasura, an open-source GraphQL engine, connects to databases and microservices and generates a production-ready GraphQL backend. YugabyteDB, a distributed SQL database, provides high performance and resilience when combined with Hasura. To get started with Hasura and YugabyteDB on Google Kubernetes Engine (GKE), users need to set up a Kubernetes cluster, install YugabyteDB using Helm, create a sample database, and configure Hasura to use YugabyteDB. Once set up, users can perform basic CRUD operations such as querying data, adding new entries, updating existing entries, and deleting entries using GraphQL. With Hasura and YugabyteDB, developers can easily build applications and microservices against the database, taking advantage of its benefits including high performance, resilience, and scalability.
