HotChocolate - Apollo Tracing

To investigate what’s going on inside your GraphQL backend I would recommend to enable Apollo tracing. You can always enable this but as this has a (small) performance impact, a better way is to enable it on demand.

In HotChocolate you can specify this through the QueryExecutionOptions:

services.AddGraphQL(services=>
SchemaBuilder.New()
.AddQueryType<QueryType>()
//Removed other types
.AddType<IdentificatieType>().Create(),
new QueryExecutionOptions()
{
TracingPreference = TracingPreference.OnDemand
});
view raw Startup.cs hosted with ❤ by GitHub

After doing that, tracing will be activated when ad GraphQL-Tracing HTTP header with a value of 1 is added to the request.

Now your GraphQL result will not only contain the data but also tracing information. GraphQL tools like GraphQL Playground can visualize this data:

If the tracing information is not shown, check your GraphQL Playground settings and see if "tracing.hideTracingResponse" is set to false.

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
