Dedicated search nodes
Currently, Atlas Search (mongot) is collocated with Atlas (mongod) on the same database deployment. Today, I have to size their workload based on both search and database requirements, which introduces the possibility of resource contention between their database and search deployment. I'd like to scale my search deployment independently of my database deployment.

We have a private preview available for this feature. Please enroll in our early access program here ( https://www.mongodb.com/dasal ) if interested or reply to this update.

Today, Atlas Search runs on all nodes of your cluster. I would like to limit the nodes that queries run on so I can isolate my transactional workload from my search workload.
