Implement Dataloaders (N+1 issue) with middleware or follow docs example

Hi all, I am trying to incorporate Dataloaders (https://docs.graphene-python.org/en/latest/execution/dataloader/) to our schemas to reduce load on our DB. However, I was wondering if anyone has had experience using either a [middleware](https://jerrynsh.com/solving-n-1-in-graphql-python-with-dataloader/) implementation vs. the ones outlined in the docs?

I also found that [saleor ](https://github.com/mirumee/saleor/blob/master/saleor/payment/dataloaders.py)uses a slightly different approach that is more similar to what was suggested by the docs. Just wondering if any1 has had experience using this feature in a bigger project.

Start by comparing the Graphene dataloader documentation with the linked middleware article and Saleor's dataloaders.py example. The issue does not identify a repository file, test, concrete implementation target, or definition of done, so the desired approach and completion criteria need to be established first.
