Resource Overview​

Azure Cosmos DB for Apache Cassandra can be used as a data store for applications created for Apache Cassandra. This compatibility means that existing Cassandra applications can communicate with the Cassandra API using existing Apache drivers that comply with CQLv4. In most cases, you can switch from using Apache Cassandra to the Cassandra API simply by updating the connection string. Using the Cassandra API allows you to interact with data stored in Azure Cosmos DB using CQL (Cassandra Query Language), Cassandra-based tools (such as cqlsh), and familiar Cassandra client drivers.
