There are a few ways you can explore your data in CosmosDB, either via the Azure Portal or with the Azure CosmosDB Graph Explorer - here. However, I wanted a quicker way that I can run queries and check results and performance locally so I created a console app that allows you to do just that.
One added benefit is that the project can also act as a playground for future experimentation with the SDK or other libraries and features that you might want to add to your own implementation.
You can find the project on GitHub. Check it out and let me know what you think.
Bonus: Since it’s a .NET Core project, this can be run on both Windows or Linux - Check the README for more details.
