Azure Synapse Link allows you to directly access Azure Cosmos DB analytical store using Azure Synapse Analytics without complex data movement. Any updates made to the operational data are visible in the analytical store in near realtime with no ETL or change feed jobs. You can run largescale analytics against analytical store, from Azure Synapse Analytics, without additional data transformation.

With Azure Synapse Link, you can run analytical queries against an Azure Cosmos DB analytical store, a column store representation of you data, while the transactional operations are processed using provisioned throughput for the transactional workload, over the Cosmos DB row-based transactional store. The analytical workload is independent of the transactional workload traffic without consuming any of the throughput provisioned for your operational data.

Azure Cosmos DB analytical store follows a consumption-based pricing model, which is based on data storage and analytical read/write operations and queries executed. It doesn’t require you to provision any throughput, as you do today for the transactional workloads. Accessing your data with highly elastic compute engines from Azure Synapse Analytics makes the overall cost of running storage and compute very efficient.

***Network isolation using private endpoints** - You can control network access to the data in the transactional and analytical stores independently. Network isolation is done using separate managed private endpoints for each store, within managed virtual networks in Azure Synapse workspaces. To learn more, see how to [Configure private endpoints for analytical store](analytical-store-private-endpoints.md) article.
