QuestDB

QuestDB is the fastest open source time-series database

Hi 👋, we're the team behind QuestDB

Banner with illustration of QuestDB, the open source time series database

QuestDB is an open-source time-series database for high throughput ingestion and fast SQL queries with operational simplicity. It supports schema-agnostic ingestion using the InfluxDB line protocol, PostgreSQL wire protocol, and a REST API for bulk imports and exports.

The project is built from scratch in zero-GC Java and C++, without code dependencies.

Our live demo includes a NYC taxi trips dataset of 1.6 billion rows, market data ingested live from the Coinbase API, and a geospatial dataset.

🤝 Contributing

We are always happy to have contributions to the project: source code, documentation, bug reports, feature requests or feedback. To get started, go to good first issues, check out our contribution guide and propose some changes by forking the repo and opening a pull request.
