Azure Cosmos DB Graph API is the first cloud database to provide graph functionality over a globally distributed managed service. This has enabled users to explore new ways of consuming their data with the use of the Gremlin language while still benefitting from global distribution, elastic scalability in storage and throughput, guaranteed low latency, consistency models, and enterprise-ready SLAs of Azure Cosmos DB.
In December, Azure Cosmos DB Graph API became generally available. This release includes several critical updates to the performance and latency, as well as expanding the application platforms that can be used with it.
