Entity Framework Query Batching

I’ve been an NHibernate fan for a long time, but on my recent projects I’m making the switch to Entity Framework.

Although I like the overall experience, there are still lot of features missing.

One of the things I liked about NHibernate was the support for query batching using the NHibernate Future<> syntax.

This allowed you to write multiple simpler queries instead of writing one complex one. The moment you try to read one query result, all batched queries are sent in 1 command(!) to the database and the results are returned.

Although a similar feature does not exist in Entity Framework out-of-the-box, you can use the EntityFramework.Extended library to get this functionality. This library extends the functionality of Entity Framework with the following features:

In this case I’m looking at the Future Queries feature:

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...
