## What it is
A TypeScript library implementing the PubSubEngine and AsyncIterator interfaces from graphql-subscriptions on top of Redis Pub/Sub. It lets GraphQL subscription managers scale across multiple server instances by sharing events through Redis.

## Use cases
- scale graphql subscriptions across multiple server instances
- publish graphql subscription events via redis pub/sub
- use async iterators for graphql subscriptions
- dynamically create subscription topics from query args
- subscribe to redis topics with patterns in graphql

## When to choose
- you run multiple graphql server instances and need shared subscription state
- you already use apollo's graphql-subscriptions and need a redis-backed engine

## When to avoid
- you run a single graphql server instance where in-memory pubsub suffices
- you need persistent event storage rather than fire-and-forget pub/sub
