We just launched our latest feature: Snowflake as a Data Source. Now, let’s demo how to connect Snowflake and Propel via a GraphQL API that’s perfect for building in-product analytics in minutes, instead of months.
In this short tutorial, we’ll be helping you build a Snowflake data app with GraphQL. Data apps are customer-facing web or mobile apps that include native, large-scale, aggregate data analysis into their product functionality and core workflows.
Before you get started, you’ll need to have your data already loaded into Snowflake data platform. (If you’re interested in learning more about using Snowflake for data analytics, consider subscribing to our newsletter for free educational content.)
To start building a data app inside Propel with Snowflake as your Data Source, you just need to complete these five easy steps:
First, you will need to create a user, role, and warehouse for Propel in your Snowflake account. (If you need a Propel account, join our waitlist, and we’ll onboard you as soon as we can!) Then, you can create the Snowflake Data Source inside Propel’s Console by entering your Snowflake connection details.
Propel will connect and run a series of checks to validate that the connection has the correct permissions.
Once connected, you can operationalize a Snowflake table by creating a Data Pool inside Propel, which will start the sync process. When using Propel, a Data Pool automatically creates an optimized mirror of your table. There’s no need for any pipelines or data engineering.
While creating the Data Pool, you will need to indicate the table you want to operationalize and its primary timestamp column in the Console.
With your data operationalized, you can define the Metrics you want to use in your data app. Metrics are the analytics measures you want to track, and they can be of different types: SUM, COUNT, COUNT_DISTINCT, MIN, MAX, and AVERAGE.
Once you configure your Metric settings in Propel, you can select the columns you want to expose as Dimensions. Dimensions are the different ways you can filter Metric data to uncover insights. When defining a customer-facing Metric, you can control which columns are exposed to the public via Dimensions.
Propel gives you a GraphQL API that is always up and always performant in just a few easy steps. Once you have your Metric defined, you can try Propel’s GraphQL Explorer to query the Metric data in the format you are going to use: a Time Series, a Counter, or a Leaderboard.
Looking at the top-right of the GraphQL Explorer, you’ll notice the fast response times you get with Propel’s high-performance GraphQL API. In this example, the response time is about 500 milliseconds (end to end) when querying hundreds of thousands of records.
The Metric you defined previously is now available via the GraphQL API. Using the technology stack of your choice, you can build in-product analytics into your app. You didn’t have to do any data engineering, beyond loading your data to Snowflake.
We are now onboarding Snowflake users first as fast as we can. We are excited to see what you build with Propel!
