Microsoft Azure Data Fundamentals DP-900 Practice Question
Your company runs an on-premises application that stores its data in an Apache Cassandra cluster and communicates by using standard CQL drivers. You plan to migrate this data layer to Azure with as few code changes as possible by creating an Azure Cosmos DB account. Which Azure Cosmos DB API should you choose to meet the requirement?
Azure Cosmos DB offers multiple logical APIs that provide wire-protocol compatibility with popular NoSQL data models. The Azure Cosmos DB for Apache Cassandra API implements the same partitioning model, data types, and CQL protocol used by open-source Cassandra, allowing existing Cassandra drivers and queries to work without modification. Choosing the Core (SQL), Gremlin, or Table APIs would require rewriting the application to use different query languages and SDKs, so they are not suitable when the goal is to avoid code changes.
