What is HydraDB?

HydraDB is an open-source, distributed, transactional time-series database designed for high throughput writes and sub-millisecond query evaluation on billions of rows.

It combines the architectural elegance of log-structured merge trees with modern vector processing engines to maximize hardware utilization.

Key Features

• Distributed Scaling: Multi-leader replication built on Raft consensus.
• High Compressibility: Dynamic delta-of-delta and Gorilla encoding.
• SQL Compatible: Native query compilation to machine code.
