🚀 Features

GraphOS Enterprise: Coprocessor read access to request uri, method and HTTP response status codes (Issue #2861, Issue #2861)

We've added the ability for coprocessors to have read-only access to additional contextual information at the RouterService and SubgraphService stages:

The RouterService stage now has read-only access to the request from the client:

• path (e.g., /graphql)
• method (e.g., POST, GET)

The RouterService stage now has read-only access to the overall response to the client:

• status_code (e.g. 403, 200)

The SubgraphService stage now has read-only access to the response of the subgraph request:

• status_code (e.g., 503, 200)

🐛 Fixes

Coprocessors: Empty body requests from GET requests are now deserialized without error

Fixes a bug where a coprocessor operating at the router_request stage would fail to deserialize an empty body, which is typical for GET requests.

Helm: Router chart now supports extraContainers to run sidecars

Our Helm chart now supports extraContainers in an effort to simplify the ability to run containers alongside Router containers (sidecars) which is a useful pattern for coprocessors.

Migrate away from unimplemented coprocessor.subgraph.all.response.uri

We have removed a completely unimplemented coprocessor.subgraph.all.response.uri key from our configuration. It had no effect, but we will automatically migrate configurations which did use it, resulting in no breaking changes by this removal.

The External coprocessing documentation is now up to date, with a full configuration example, and the newly added fields.

Example: Rhai-based cache-control response header management

A new Rhai example demonstrates how to recreate some of the behavior of Apollo Gateway's subgraph cache-control response header behavior. This addresses some of the need identified in #326.
