Become a Traffic Wizard: A Beginner's Guide to Routing Traffic with Apache AGE

Introduction

If you're an aspiring web developer or system administrator, you're probably familiar with the term "traffic routing." Essentially, traffic routing refers to the process of directing users from one spot to another. In other words, it's a route directory in maps and also the backbone of how the internet works by requesting to the appropriate server or resource in a distributed computing environment.

Apache AGE is a powerful open-source software that can be used to route traffic, balance loads, and improve overall performance. However, for beginners, it can be overwhelming to know where to start with Apache AGE.

That's why I've put together this comprehensive guide to help you become a traffic routing wizard using Apache AGE. In this blog post, we'll cover the basics of traffic routing for optimizing your routing configuration. Whether you're just starting out or you're looking to improve your existing skills, this guide has something for everyone. So, let's dive in and learn how to route traffic like a pro with Apache AGE!

Background

For this guide, we'll be using the SkyTrain lines in Vancouver as our example dataset.

The SkyTrain is a rapid transit system that serves the Metro Vancouver area in British Columbia, Canada. The system consists of three lines and 53 stations, where 20 stations are served by the Expo Line, 14 by the Millennium Line, 15 by the Canada Line, 1 by both the Expo and Canada Lines, and 3 by both the Expo and Millennium Lines
Skytrain and Seabus Map ( to visualize the graphs that we have created in order to better understand the data.

Let's first view our entire map using the following query:

SELECT *

FROM cypher('SkyTrain', $$

    MATCH (n)-[r]-(m)

    RETURN n, r, m

$$) AS (n agtype, r agtype, m agtype);

The displayed graph may initially show an unorganized view of the nodes and relationships; however, by changing the layout options (or dragging each node to a specific position manually), we are able to better organize them. For this example, I have used the 'Klay' layout to view the path in a straight line.

Finally, running the query below will show the most optimal path from 'Richmond-Brighouse' station to 'Lafarge Lake-Douglas' station.

SELECT paths, rel

FROM cypher('SkyTrain', $$

    MATCH paths = (a:Station {name: 'Richmond-Brighouse'})-[:Route*]-(b:Station {name: 'Lafarge Lake-Douglas'})

    WITH paths, relationships(paths) AS rels

    UNWIND rels AS rel

    WITH paths AS paths,

        rel AS rel,

        collect(rel.time) AS times,

        sum(rel.time) AS total_time

    RETURN paths, rel, times, total_time

$$) AS (paths agtype, rel agtype, times agtype, total_time agtype)

ORDER BY total_time

LIMIT 1;

This query is slightly altered from the previous query in the 'Finding the Optimal Path' section. The relationships are included in the output this time, and only the top row of the result is chosen as it will be the most time efficient path.

Conclusion

In this guide, we've explored how to route traffic using Apache AGE. We began by discussing the importance of setting up data that is relevant to a practical application, and used the SkyTrain system in Vancouver as an example dataset. We then walked through the steps involved in setting up the data, including creating nodes for each station and relationships between them to represent the connections between stations. Finally, we looked at different methods on producing and visualizing tables and graphs that will be of use upon deciding on the most optimal path.

With the skills and knowledge you've gained from this guide, you'll be well-equipped to take on any traffic routing challenge that comes your way. Start using Apache AGE today and become a traffic routing wizard!
