/ About /

QuestDB is an open-source, high-performance time-series database designed for demanding workloads such as trading, finance, and aerospace. It offers ultra-low latency, high ingestion throughput, and a multi-tier columnar storage engine with native Parquet and SQL support. Data is stored in open formats to avoid vendor lock-in and is accessible to AI agents and LLMs via standard SQL and REST APIs.

/ How it works /

QuestDB ingests data via WAL into a time-partitioned columnar engine, automatically tiers historical data to open Parquet format on object storage, and exposes a unified SQL surface and REST API for querying across all tiers.

/ Who it's for /

Data engineers, quant developers, and AI infrastructure teams at exchanges, banks, and high-performance workload environments
