## AI overview

This article describes Reco's migration from Postgres to ClickHouse Cloud to support its SaaS security platform. Reco processes billions of JSON events, row reads, and row writes while scanning petabytes of historical tenant data. The article explains that ClickHouse provides the performance and scale needed for near-real-time monitoring, detection, and response, while reporting lower costs and higher speed after the migration.
