Streaming Subscriptions in GraphQL
summary
Hasura adds streaming subscriptions to GraphQL that send only new rows instead of full live-query snapshots, proven to handle millions of rows updated per second in production tests; implementation uses websockets, a configurable batch size (demo used batch size 5) and a single-column cursor (timestamps recommended). Features include Hasura permissions and relationships in streamed results, client demos built with React + react-query and graphql-ws, alpha/beta available soon, and no backpressure support yet so clients can be overwhelmed.
