Question
You have operational data in an Azure Cosmos DB for NoSQL database. Database users report that the performance of the database degrades significantly when a business analytics team runs large Apache Spark-based queries against the database. You need to reduce the impact that running the Spark-based queries has on the database users. What should you implement?

Explanation
Azure Synapse Link for Cosmos DB creates a tight integration between Azure Cosmos DB and Azure Synapse Analytics. It allows you to run large-scale analytics on operational data without affecting the performance of the operational workloads in Cosmos DB. Synapse Link uses a columnar store to replicate data from Cosmos DB. This replication is asynchronous and does not impact the transactional store's performance, making it ideal for scenarios where operational workloads and analytical workloads need to coexist without impacting each other.
