Segment provides an excellent way to collect data through a single schema and API. That's why it's also often used as middleware to track customer behavior data for product analytics and analytics use cases in marketing. It also offers a free tier.

In this article, you'll learn how to set up Segment for your web application and store the captured data in Snowflake, a popular data warehouse solution.

What Is Segment?

Many organizations are eager to collect customer behavior data. Although many free tools (like Google Analytics) offer this capability in one way or another, they often lock in their users by making it hard or impossible to get the data out. This restriction seriously limits the use cases for this data.

When it comes to data collection, Segment was one of the first tools to offer a unified tracking API via Connections, allowing users to send and store data in their tool of choice. It's effortless to set up and very robust, and it delivers data in real time.

On top of that, Segment offers two more capabilities that put it in the CDP software category. It offers a data catalog and quality checks in a feature called Protocols. Segment also allows you to create customer segments and expose them to an organization's marketing stack, enabling content personalization on websites, emails, and other customer touchpoints.

What Is Snowflake?

Just like Segment has banked on the growing need to adequately collect customer data, Snowflake has made it convenient to store and process large amounts of data for analytical purposes. It competes with Google BigQuery, Databricks, and Firebolt to offer the fastest data warehouse solution. Snowflake is unique in that it can be deployed on any major cloud vendor. You can choose between Google Cloud Platform, Amazon Web Services, or Microsoft Azure.

Data warehouses store data in a columnar format, and both storage and computing resources can be scaled out more or less automatically. Tracking behavior on a popular digital product often results in millions of events logged per day. Nothing matches the performance of data warehouses like Snowflake for processing OLAP workloads.

Furthermore, while data warehouses used to be notoriously hard to load data into, modern data warehouses like Snowflake offer various options for loading data and registering it in a schema, both in batch and stream.

Building an Analytics Solution for Your Product Using Segment and Snowflake

In this section, you'll build a real-time pipeline in which Segment collects data from a web application and stores it in a Snowflake data warehouse.

Prerequisites

There are a couple of prerequisites to set up product analytics tracking with Segment and Snowflake:

  • Create a Segment account. Don't worry; a limited free plan should get you up and running.
  • Create a Snowflake account. Snowflake offers a thirty-day trial with $400 in credits that you can spend on storage and compute capabilities. Although Snowflake is deployed on one of three major cloud providers, you don't need an account with the provider. Snowflake handles the complete deployment.

Configuration

Once you've fulfilled the above prerequisites, you'll need to configure the source and destination of the data you'd like to analyze.

Setting Up a Source

Segment offers numerous ways of collecting data. You can choose simple client-side tracking via JavaScript or server-side tracking with one of Segment's server connectors, such as Node.js, PHP, or Python. There are also integrations with cloud and MarTech tools such as HubSpot.

In this example, you'll integrate Segment into a WordPress website using a tracking snippet from Segment. To start, create a JavaScript source by going to Connections and clicking Add Source:

Then, make some minor configuration changes to the source by providing an appropriate name and the hostname of the website where you'll be adding the JavaScript snippet:

Implementing the Source Script

Once you've done that, you'll get a very compact piece of code. Once you install this code on your website, it will load the Segment API, which contains a variety of methods to track events such as page views and clicks. The code also contains your unique tracking ID in two places in order to identify your data source. To view an example Segment snippet, check out this fiddle.

When you implement client-side tracking, there are three main ways to implement the tracking script. You can:

  • Use a tag management solution like Google Tag Manager to install the snippet, and use various triggers to fire your events.
  • Ask a developer to hard-code the snippet in the <head> section of your website, and provide instructions on how and what event should be fired.
  • Use a plugin. Many content management systems like WordPress offer plugins for injecting code snippets in the header or footer of the website.

In the example screenshot below, the Head & Footer Code WordPress plugin was used:

Configuring the Destination

To ingest data into Snowflake with Segment, you'll need the following:

  • A database to store the tracked events
  • A role to use and manage the database
  • A user to grant the role to
  • A small data warehouse to process the data

While all these objects can be created via Snowflake's GUI, you can simply run the following queries in a Snowflake worksheet (don't forget to set a safe password):

Setting Up the Destination

Next, set up a destination via the Segment GUI by going to Connections and clicking Add Destination. After selecting Snowflake, you'll be asked to provide some credentials:

Take note that you do not use the account ID that you find in the admin settings of your Snowflake organization. Instead, for the Account field in the credentials section, you're looking for the first part of the hostname of your account if you open Snowflake's classic console:

Testing

Now that you've configured everything, it's time to test that it's all working correctly.

Testing the Pipeline

First, you should test your pipeline. Go to the Debugger section of the source you've just created, and generate a few page hits on the website where you've implemented the tracking snippet. If everything goes well, the hits will be registered in real time:

Querying Data in Snowflake

Once the functioning of your pipeline is confirmed, you can query the destination table(s) in Snowflake. If you're doing this with a user other than the one you authenticated Segment with, you need to grant it the same USAGE privileges on the database and data warehouse.

The query below prints the page views you triggered to test your data pipeline:

SELECT * FROM <YOURWEBSITE_COM>.PAGES

Depending on the kinds of events you log, Segment will create new tables in the schema, which can be queried in an analogous manner.

Caveats

Tracking your users' behavior via Segment and Snowflake is easy to set up, but has some caveats.

No Historical Data

Segment doesn't integrate with your existing data sources. It's not a data integration tool (like Fivetran) that lifts data from an existing data storage or software-as-a-service (SaaS) tool and moves it to Snowflake. On the contrary, Segment is plugged directly into your digital product, collecting real-time data that gets synced to your Snowflake data warehouse.

No Real-Time Availability

Although Segment collects real-time data from your digital product, it doesn't stream it to Snowflake. The data gets stored in Segment and is frequently synced to all configured destinations. When you have a Business plan with Segment, you can configure a selection of data sources and the synchronization time. Nevertheless, the data will only be fresh at the start of a new interval.

Conclusion

Both Segment and Snowflake are popular SaaS solutions. The former is for collecting real-time product data, and the latter is for storing and processing it. This article outlined how you can easily set up a product analytics pipeline with a JavaScript source and a Snowflake destination in Segment.
