TRY THE POSTGRES THAT TOOK CLERA FROM 100% CPU TO 10–20%, WITH $300 IN FREE CREDITS

Summary from the TLDR Dev newsletter

Clera is an AI talent agent. Its Postgres database was stuck at 100% CPU for six straight days. Primary-key lookups took three seconds, and writes failed under load. So they tested Supabase, Neon, PlanetScale and ClickHouse Managed Postgres on their own production data. ClickHouse won. They then migrated 500+ tables overnight [5], and CPU now typically runs at 10–20%.
