SnowPlow

Introduction

SnowPlow is the world's most powerful web analytics platform. It does three things:

  • Identifies users, and tracks the way they engage with a website or web-app
  • Stores the associated data in a scalable “clickstream” data warehouse
  • Makes it possible to leverage a big data toolset (e.g. Hadoop, Pig, Hive) to analyse that data

To find out more, please check out the SnowPlow website and SnowPlow Wiki.

SnowPlow technology 101

The repository structure follows the conceptual architecture of SnowPlow, which consists of five loosely coupled stages:

architecture

To briefly explain these five sub-systems:

  • Trackers fire SnowPlow events. Currently we have a JavaScript tracker; iOS and Android trackers are on the roadmap
  • Collectors receive SnowPlow events from trackers. Currently we have a simple CloudFront-based collector; there is also a prototype node.js-based collector, SnowCannon
  • ETL (extract, transform and load) cleans up the raw SnowPlow events, enriches them and puts them into storage. Currently we have a Hive-based ETL process
  • Storage is where the SnowPlow events live. Currently we store the SnowPlow events in a Hive-format flatfile structure on S3
  • Analytics are performed on the SnowPlow events. Currently we have a set of ad hoc analyses written in Hive

For more information on the current SnowPlow architecture, please see the Technical architecture.

Contributing

We're committed to a loosely-coupled architecture for SnowPlow and would love to get your contributions within each of the five sub-systems.

If you would like help implementing a new tracker, trying a different ETL approach or loading SnowPlow events into an alternative database, get in touch!
