Using Cosmos DB For Graph Data

Jose Mendes has an introduction to the Cosmos DB graph engine:

Gremlin is the graph traversal language of Apache TinkerPop, an open source Graph Computing Framework. Gremlin allows the users to write complex queries to traverse their graphs by using a composed sequence of steps, with each step performing an operation on the data stream (further details here). There are 4 fundamental steps:

· transform: transform the objects in the stream

· filter: remove objects from the stream

· sideEffect: pass the object, but yield some side effect

· branch: decide which step to take
