PostHog is migrating its warehouse product from DuckDB to a Trino-based architecture due to scaling limitations with single-node DuckDB instances in multi-tenant cloud environments. The company previously switched from ClickHouse to DuckDB five months ago for better query optimization but found it struggled with increasingly complex customer workloads.
Background
PostHog is a product analytics platform that recently rebuilt its data warehouse offering. DuckDB has gained popularity as an embedded OLAP database, while Trino provides distributed SQL query engine capabilities for large-scale analytics.
