DocumentDB: Partitioned collections for higher storage and throughput
The latest Azure DocumentDB service update includes support to create partitioned collections, which can support larger data volumes and process more requests. Partitioned collections support up to 250 GB of storage and 250,000 request units per second of provisioned throughput. (You can increase both limits by filing a support ticket.) You can create partitioned collections via the Azure portal, REST API version 2015-12-16, and SDK versions 1.6.0 and newer in .NET, Node.js, Java, and Python. The programming model introduces partition keys during collection creation and as an argument for read, write, query, and execute stored-procedure operations on documents.
