| description.long | A time-series and observability database that consolidates multiple signal types—metrics, logs, traces, and events—into a single queryable system using standard protocols like OpenTelemetry and Prometheus. It uses columnar storage on object storage for cost-effective scalability and provides both open-source and fully-managed cloud deployment options. | QuestDB is an open-source time-series database engineered for low latency, delivering ultra-low latency ingestion, high throughput, and multi-tier storage for demanding time-series workloads. |
