Snowplow is an enterprise-strength marketing and product analytics platform. It does three things:
- Identifies your users, and tracks the way they engage with your website or application
- Stores your users' behavioural data in a scalable "event data warehouse" you control: in Amazon S3 and (optionally) Amazon Redshift or Postgres
- Lets you leverage the biggest range of tools to analyze that data, including big data tools (e.g. Spark) via EMR or more traditional tools e.g. Looker, Mode, Caravel, Re:dash to analyze that behavioural data
Snowplow technology 101
The repository structure follows the conceptual architecture of Snowplow, which consists of six loosely-coupled sub-systems connected by five standardized data protocols/formats:
To briefly explain these six sub-systems:
- Trackers fire Snowplow events. Currently we have 12 trackers, covering web, mobile, desktop, server and IoT
- Collectors receive Snowplow events from trackers. Currently we have three different event collectors, sinking events either to Amazon S3, Apache Kafka or Amazon Kinesis
- Enrich cleans up the raw Snowplow events, enriches them and puts them into storage. Currently we have a Hadoop-based enrichment process, and a Kinesis- or Kafka-based process
- Storage is where the Snowplow events live. Currently we store the Snowplow events in a flatfile structure on S3, and in the Redshift and Postgres databases
- Data modeling is where event-level data is joined with other data sets and aggregated into smaller data sets, and business logic is applied. This produces a clean set of tables which make it easier to perform analysis on the data. We have data models for Redshift and Looker
- Analytics are performed on the Snowplow events or on the aggregate tables.
For more information on the current Snowplow architecture, please see the Technical architecture.
