Case Study: Substack achieves real-time data replication with Artie

Substack accelerates decision-making with real-time data replication

Substack, a leading subscription network, needed to replicate data from its production Postgres database to Snowflake in real time without straining its infrastructure. Their previous batched ETL process caused delays and reduced productivity. They chose Artie, a change data capture (CDC) streaming solution, to address this challenge.

Artie implemented a complete CDC solution that efficiently syncs data with an average latency of 10-15 seconds, handling schema changes and complex data types automatically. For Substack, Artie now transfers approximately 1 billion rows per month, enabling faster A/B testing, ensuring higher data integrity, and lowering the total cost of data infrastructure ownership.
