Clera, an AI-powered talent matching platform, migrated its 500+ GB Postgres database from a previous vendor to ClickHouse Managed Postgres overnight, resolving severe performance issues where CPU was pinned at 100% for days and point lookups took seconds. The company evaluated Supabase, Neon, PlanetScale, and ClickHouse Managed Postgres on its real workload before selecting ClickHouse, achieving CPU reduction to 10-20% post-migration.
