Hi, I am from Azure Cosmos DB Engineering Team.

Please feel free to send us the details of your workload that suffered from poor performance to [email protected] (it is a direct way to reach the engineering team and it does not cost anything), and we can help determine why and provide with the recommendations.

For best practices and performance optimizations, the following links will help:

We are doing a full refresh of our docs (rewriting a lot of the older content and adding new technical content). We welcome feedback on how we can make the docs better and invite everyone to contribute via public PR/Github. If there are any topics that are missing in our docs or are not easily discoverable, please let us know. We will make sure to address it.

We are committed to building a great community. As a relatively young database, we have ton of work ahead, but we are super committed to making sure we make developers successful.
