Is there any count limitation on items per container in cosmos DB?

Question

what is the maximum number of items that a container can have in the cosmos db?

Answer 1

There are no storage limits for a container in Cosmos DB. In fact, storage capacity is infinite by virtue of it being horizontally scalable. Keep adding data and the service will automatically provision additional partitions behind the scenes. One thing to keep in mind however, is as your storage grows, so does the amount of throughput required to manage it, because each partition requires its own compute to access the data stored on it.
