Azure Cosmos DB
Azure Cosmos DB is Microsoft’s globally distributed, multi-model database. Azure Cosmos DB enables you to elastically and independently scale throughput and storage across any number of Azure’s geographic regions. It offers throughput, latency, availability, and consistency guarantees with comprehensive service level agreements (SLAs). Azure Cosmos DB provides APIs for the following data models, with SDKs available in multiple languages:
- SQL API
- MongoDB API
- Cassandra API
- Graph (Gremlin) API
- Table API
This article explains how to read data from and write data to Azure Cosmos DB using Azure Databricks. For more the most up-to-date details about Azure Cosmos DB, see Accelerate big data analytics by using the Apache Spark to Azure Cosmos DB connector.
This connector supports the core (SQL) API of Azure Cosmos DB. For the Cosmos DB for MongoDB API, use the MongoDB Spark connector. For the Cosmos DB Cassandra API, use the Cassandra Spark connector.
Create and attach required libraries
- Download the latest azure-cosmosdb-spark library for the version of Apache Spark you are running.
- Upload the downloaded JAR files to Databricks following the instructions in Upload a Jar, Python egg, or Python wheel.
- Install the uploaded libraries into your Databricks cluster.
Use the Azure Cosmos DB Spark connector
The following Scala notebook provides a simple example of how to write data to Cosmos DB and read data from Cosmos DB. See the[Azure Cosmos DB Spark Connector][azure cosmos db spark connector] project for detailed documentation.
