What does QuestDB do?
QuestDB is an open-source time-series database designed to handle demanding data workloads with exceptional performance. It specializes in ingesting massive amounts of time-stamped data at high speeds—up to 8 million rows per second per server—while providing fast SQL query capabilities. The database uses SIMD acceleration and a multi-threaded engine to deliver ultra-low latency responses, making it suitable for real-time analytics scenarios where speed matters most.
What sets QuestDB apart is its developer-friendly approach with standard SQL support and Postgres protocol compatibility, meaning developers can use familiar tools and syntax. It features a multi-tier storage engine that automatically manages data across different storage types while maintaining query performance. The database supports Parquet format natively, ensuring data portability and preventing vendor lock-in. Its architecture includes specialized time-series functions like SAMPLE BY for time-bucketing, ASOF JOIN for time-aligned data merging, and streaming materialized views for continuous computation.
This database benefits organizations dealing with high-volume time-series data, particularly in financial services, trading platforms, IoT applications, and real-time monitoring systems. Companies use QuestDB for processing market tick data, analyzing trading patterns, monitoring industrial equipment, and handling sensor data from connected devices. Its open-source nature and SQL-first approach make it accessible to development teams who need both raw performance and the flexibility of standard query languages.
