Hydra is a modern, open source replacement for enterprise data warehouses. It’s fast and feature-rich so devs can build better analytics, quicker.
Hydra implements an open source columnar engine to Postgres, driving 23X query performance, better cache hit rates, and scalability over basic Postgres. When comparing to traditional warehouses, Hydra delivers 1500X more throughput to enable realtime analytical workloads.
Results in seconds, smaller is better.
Review Clickbench for comprehensive results and the list of 42 queries tested.
This benchmark represents typical workload in the following areas: clickstream and traffic analysis, web analytics, machine-generated data, structured logs, and events data. It covers the typical queries in ad-hoc analytics and real-time dashboards.
Hydra delivers 1500X more throughput than traditional warehouses to enable realtime analytical workloads. This is accomplished with transactional heap tables.

The Hydra Docker image is a drop-in replacement for postgres Docker image.
You can also try out Hydra locally using docker-compose.
git clone https://github.com/hydradatabase/hydra && cd hydra
cp .env.example .env
docker compose up
psql postgres://postgres:hydra@127.0.0.1:5432
