Ad-hoc Learning

Gremlin is the preferred language when it comes to defining traversals in DataStax Enterprise Graph. This is also true for DSE GraphFrames. In this unit, we will describe a general strategy of using Gremlin API with DSE GraphFrames

In this unit, you will be introduced to DSE GraphFrames. DSE GraphFrames is an alternative OLAP engine for DataStax Enterprise Graph. It is designed around our DataStax Enterprise Analytics offering and it enables a unique way of interacting with DataStax Enterprise Graph using various Spark APIs and tools.

A Gremlin traversal can be executed using either real-time (OLTP) engine or analytic (OLAP) engine. The latter execution results in a Gremlin OLAP traversal. In this unit, you will learn about Gremlin OLAP traversals.

Welcome to the Graph Analytics with DataStax Enterprise Graph course. Graph analytics is about delivering value from your graph data by combining and applying well-known analysis steps into a data analysis workflow, with the goal of doing data-driven decision making, information discovery, graph exploration, and all kinds of ad-hoc analysis.

In this unit, we will be learning about bulking optimization. Bulking is the merging of multiple traversers into a single one.

In this unit, we are going to discuss traversal behavior and predictability. You might be using DataStax Enterprise Graph because you anticipate having a large dataset. In this case, being able to rather and understand the characteristics of your graph is critical to developing traversals that will perform well at scale.

Recommendation engines are a really good common use case for graph. In this unit, we see how we might build a recommendation engine for our KillrVideo project using Gremlin and DataStax Enterprise Graph.

The sack traversal in Gremlin is kind of like giving an empty bag (or sack) to every gremlin traverser in your graph. The gremlins carry their bag as they walk around the graph, and they collect properties about the graph to store in the bag. In this unit, you will learn about the sack traversal.

It is a really good idea to customize the language you use to talk about graph traversals to the specific domain. In this unit, you will learn about domain-specific traversals.

 The mutating traversal adds or removes vertices, edges, or properties to the graph. In this unit, you will learn about mutating traversals.
