QuestDB is a high performance, open-source database that efficiently stores, accesses and analyzes timestamped data. Through extended SQL and compatibility with your favourite tools, it's quick to get started and simple to apply. 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, without code dependencies.
