Aside: why is there not an RSS feed for the WunderGraph blog?

I think Jens Neuse is making two important observations about GraphQL:

1. GraphQL's single URL/endpoint [1] is possibly an anti-pattern

2. ETags are important for Cache-Control and Concurrency-Control on REST endpoints

The concept of prepared statements is useful for my SQL-centric brain. WunderGraph effectively creates a REST endpoint for each prepared statement (GraphQL DML). Like prepared statements in SQL, WunderGraph uses query metadata to determine the types of input parameters and the shape of the JSON response.

Kyle Schrade makes an important point about canonical GraphQL queries: response payloads can be reduced by filtering JSON fields, similar to SQL projection (i.e. the columns specified in the SELECT clause). It seems that WunderGraph can potentially support both approaches by allowing optional GraphQL queries on each REST endpoint that can be used to filter the endpoint specific JSON response.

I don't see a problem allowing a generic GraphQL handler. It's just that I don't like the approach of allowing arbitrary queries from clients you cannot control. If this use case has a lot of demand I don't think I wouldn't support it. I'd just rather implement a seamless developer experience for code generation so you don't really want to not use it and lose the benefits.

I think we are on the same page. From my perspective, arbitrary queries are a vector for a Denial of Service event (both intentional and accidental). This has long been one of the use cases for Stored Procedures in SQL; restrict the public interface to guard against expensive queries (large scans and sorts). Faceted Search [1] may be a counter-example but I suspect that these interfaces are implemented at least partially with Full Text Search indexes rather than purely dynamic GraphQL/SQL.

It might be a useful exercise to prototype an online shopping site using WunderGraph.
