Azure COSMOS DB SETS default throughput for your container based on where you create the table from - portal or CQL. Azure Cosmos DB provides guarantees for PERFORMANCE and latency, with upper bounds on operation. This guarantee is possible when the ENGINE can enforce governance on the tenant's operations. Setting throughput ensures that you get the guaranteed throughput and latency, because the platform RESERVES this capacity and guarantees operation success. You can elastically change throughput to benefit from the seasonality of your application and save costs.
