Azure Cosmos DB is Microsoft’s multi-model database which supports the Gremlin query language to store and operate on graph data. > Cosmos DB Spark connector contains samples to read graph data into GraphFrames. In this post we’ll demonstrate how to build upon this connector to write GraphFrames to Cosmos DB using an Azure Databricks PySpark notebook.
