Consider a scenario, you are part of data engineering team at a retail company. you’re tasked with leveraging customer behavior and preferences to improve engagement and marketing strategies. However, the volume of daily transaction data poses challenges in effectively segmenting customers and optimizing engagement. Traditional segmentation methods fall short in scalability and real-time insights. This blog post explores how Snowpark, a powerful tool for data processing within Snowflake, can be used to perform RFM segmentation and unlock actionable customer insights.

However, RFM stands for Recency, Frequency, and Monetary Value. These metrics help categorize customers based on:

Recency: How recently a customer made a purchase.
Frequency: How often a customer makes purchases.
Monetary Value: Total amount spent by a customer

Solution with Snowflake Snowpark:

Therefore, to address these challenges, the data engineering team leverages Snowflake Snowpark, a powerful data processing engine. Hence, By implementing Snowpark, the team can efficiently analyze large volumes of transaction data and derive meaningful customer segments in real-time.



We developed a Snowpark script to process customer transaction data stored in the Snowflake database. The script performs the following tasks:

1.Data Ingestion: Reads customer transaction data from the “CUSTOMER_TRANSACTIONS” table in the Snowflake database.
2.Data Processing: Calculates key metrics such as purchase count, total money spent, and recency of purchases for each customer.
3.Customer Segmentation: Segments customers based on their purchase behavior using RFM (Recency, Frequency, Monetary) scoring logic. Customers are categorized into three segments: Platinum, Silver, and Bronze.
4.Engagement Optimization: Assigns personalized engagement strategies to each customer segment based on their behavior. For example, platinum customers receive special discounts to encourage repeat purchases, while silver customers are followed up regularly to ensure continued engagement.
5.Metadata Management: Stores segmented customer data in the “CUSTOMER_SEGMENTS” table within the Snowflake database for easy access and retrieval for further analysis.

Complete Code:


Snowpark provides a robust platform to perform RFM segmentation within Snowflake. It offers:

  • Real-time Segmentation: Snowflake Snowpark enables real-time processing of transaction data, allowing the company to segment customers dynamically based on their latest behavior.
