Public preview: Add an Azure Cosmos DB custom endpoint in IoT Hub

Azure IoT Hub now supports the ability to setup an Azure Cosmos DB account as a custom routing endpoint. This will help route device data from IoT Hub to Azure Cosmos DB directly. The feature also allows the configuration of Synthetic Partition Keys for writing data into Azure Cosmos DB which helps in optimized querying when working with large-scale data.

Many IoT solutions require extensive downstream data analysis and pushing data into hyperscale databases. For example, IoT implementations in manufacturing and intelligent transport systems require hyperscale databases with extremely high throughput to process the continuous stream of data. Traditional SQL based relational databases cannot scale optimally and also become expensive once data scale increases. Azure Cosmos DB is best suited for such cases where the data needs to be analyzed while it is being written.
