QuestDB Open Source Certified

QuestDB achieves extremely high ingestion rates—millions of rows per second—via a vectorized, columnar engine optimized for time-series workloads.

A modern SQL engine with vectorized execution delivers low-latency queries on large datasets. QuestDB supports standard SQL plus native time-series extensions such as SAMPLE BY, LATEST ON, and ASOF JOIN.

QuestDB uses open standards including Apache Parquet for storage and Apache Arrow for in-memory processing. This ensures frictionless interoperability across analytics systems with no vendor lock-in.

A compressed, columnar architecture enables efficient long-term data retention. Tiered storage and partitioned tables keep performance high while minimizing infrastructure footprint and cost.

QuestDB integrates easily with existing systems using the PostgreSQL wire protocol, Influx Line Protocol, REST, Kafka, Redpanda, and ecosystem tools like Grafana and Prometheus.

QuestDB powers mission-critical workloads across financial markets, observability, IoT, and any system requiring low-latency ingestion, real-time analytics, and high performance at scale.
