Could you please explicitly state whether it supports Gremlin API (Graph) or not?

Thank you for your interest in Azure products and services.
We are investigating and will get back to you soon.

The spark support for graph operations is mainly moving towards using GraphFrames instead of Gremlin in Spark because GraphFrames is more focused on OLAP queries and traversals.
We recommend using Cosmos DB Gremlin API for the OLTP operations and using GraphFrames for OLAP queries

Please refer to the links below

Let us know if you have any further questions.
