Oct 28, 2025 · Learn how to use Azure Cosmos DB for Apache Gremlin to store, query, and traverse massive graphs with the Gremlin graph query language of Apache TinkerPop. Predicates are used to compare values based on equality, ranges or certain patterns. Using this intuitive model as our foundation, we'll explore a variety of Gremlinq queries to extract meaningful insights from the airline network graph. For more information on Gremlin, refer to the following resources: This domain model represents a fictional airline network as a graph, where airports serve as vertices and flights between them as edges. This section of the Amazon Neptune user guide shows you how to use the Gremlin query language to access and traverse the graph data stored in your Neptune cluster. He is essentially your query language to graph databases, as SQL is the query language to relational databases. Recipes assume general familiarity with Gremlin and the Apache TinkerPop™ stack.

Jun 24, 2025 · Gremlin uses these elements to traverse and query complex networks efficiently. For example, computing the shortest path between two nodes in the graph. The entities are defined as follows: Mar 4, 2013 · For example, you can use a document collection to store graph data side by side with documents, and use both SQL queries over JSON and Gremlin queries to query the collection. This section is a brief overview of the Gremlin query language. Gremlin is a graph traversal language for querying databases with a functional, data-flow approach. For Graph API, this documentation page lists all the supported Gremlin steps: Azure Cosmos DB Gremlin Graph Support. Counting things Graph Query Languages - An Introduction A graph query language is a specialised language designed to interact with and retrieve data from graph databases or graph-like data structures. Be sure to have read the Getting Started tutorial and the The Gremlin Console tutorial. It provides guidance on leveraging Gremlin's powerful graph traversal capabilities to interact with your Neptune-based graph data. where(gt("other")). Gremlin is a query language developed as part of the Apache TinkerPop, specially designed for traversing graph databases.

Introducing Gremlin 3. 2, Neptune ML supports real-time inductive inference, which applies data processing and model evaluation in real-time on new data. A Gremlin query is a chain of operations/functions that are evaluated from left to right. 3. V(1). Examples of Conditional and Pattern Traversals in the Gremlin Query Language Conditional and pattern-based traversals enable Gremlin queries to reflect complex relationships within graph data. e.
