QuestDB is a high performance, open-source database for time series data. It delivers ultra-low latency, high ingestion throughput, and a multi-tier storage engine. Native support for Parquet and SQL keeps your data portable, AI-ready—no vendor lock-in.
QuestDB is designed from the ground up to operate as close to the hardware as possible -- eliminating ingestion bottlenecks and lowering overall hardware requirements.
The codebase is built from scratch in zero-GC Java, C++ and Rust (QuestDB Enterprise).
