Atlas scales the oplog to 5% of the cluster capacity, not to exceed 50 GB. NVMe storage requires an oplog which is 10% of the storage capacity.

MongoDB is one of the most scalable databases on the planet, and MongoDB Atlas brings you that same scalability, but with us managing it for you:

You can scale up or down on larger instance types with no application downtime

You can scale out across multiple instances with no application downtime using MongoDB’s native sharding capabilities
