QuestDB is an open-source time-series database designed for high-performance processing of time-series data. It is engineered to handle demanding workloads, making it suitable for environments such as trading floors and stock exchanges.
QuestDB delivers ultra-low latency and high ingestion throughput, capable of ingesting millions of rows per second per node. Its multi-tier storage engine ensures efficient data management, while native support for open formats keeps data portable and free from vendor lock-in.
QuestDB is the fastest-growing time-series database, offering SQL and PGwire compatibility. It supports historical data in Parquet format and allows for multiple availability zones, decoupling storage and compute for enhanced flexibility.
QuestDB leverages existing open formats like Apache Parquet, ensuring no vendor lock-in. It supports enhanced compression and encoding for both ingress and egress, making it versatile for various data processing needs. QuestDB can stream market data from feeds or sensors and apply Parquet on read, or bypass QuestDB ingest to query Parquet directly from the object store.
QuestDB powers critical financial infrastructures, such as Brazil’s leading stock exchange B3. It delivers high-performance, low-latency data management for real-time trading operations. QuestDB’s cloud-native architecture integrates seamlessly with microservices in cloud environments, offering a 99.9% uptime guarantee.
QuestDB offers easily adopted, time-series optimized SQL. It supports various time-series operations such as searching time, slicing time, navigating time, and merging time. This makes it ideal for applications requiring complex time-series data analysis.

With a team of 27 employees, QuestDB has achieved significant milestones, including being part of Y Combinator’s S20 batch and winning InfoWorld’s 2020 Best of OSS Award. The company is also recognized by Accel’s #Open100.
