GraphQL for Monolith, Microservices, and Serverless

What is Sqoop?

Sqoop (formerly QLoo) is a GraphQL Server built on top of Gloo and the Envoy Proxy.

Sqoop leverages Gloo's function registry and Envoy's advanced HTTP routing features to provide a GraphQL frontend for REST/gRPC applications and serverless functions. Sqoop routes requests to data sources via Envoy, leveraging Envoy HTTP filters for security, load balancing, and more.

Workflow with Sqoop

• Register or Discovery API Endpoints and Serverless Functions with Gloo
• Upload a GraphQL schema
• Connect Functions to your Schema's fields in a Sqoop ResolverMap

Features

• Codeless GraphQL API: Instantly deploy a GraphQL server and connect it to your data sources with configuration, zero code required.
• Dynamic Load Balancing: Load balance traffic across multiple data sources.
• Health Checks: Active and passive monitoring of your data sources.
• OpenTracing: Monitor GraphQL requests using the well-supported OpenTracing standard.
• Monitoring: Export HTTP metrics to Prometheus or Statsd.
• Client SSL: Communicate with Data Sources using TLS encryption.
• Declarative API: Sqoop features a declarative YAML-based API; store your configuration as code and commit it with your projects.
• Scalability: Sqoop scales independently of your data sources and scales infinitely.
• Performance: Sqoop leverages Envoy for its high network performance and low footprint.
• Plugins: Sqoop leverage's Gloo's plugin ecosystem to enable extending the types of data sources Sqoop can connect to.
• JSON-to-gRPC transcoding: Connect GraphQL JSON clients to gRPC data sources.

Thanks

Sqoop would not be possible without the valuable open-source work of projects in the community. We would like to extend a special thank-you to Envoy and gqlgen server library.
