QuestDB

About

QuestDB is the data platform for mission-critical workloads where data cannot be lost and batch processing is too slow. It runs real-time trading analytics, grid monitoring, fleet telemetry and mission operations at millions of events a second, with years of history kept queryable.

Data stays in open formats like Parquet, and you or any of your agents can query it in plain SQL.

QuestDB started where the problem is hardest, on the electronic trading floor, and built outward into energy, aerospace and robotics. Today 7 of the largest 20 investment banks use it, as do energy companies and makers of aircraft, rockets and satellites. Its engineers work with each customer's team on the whole solution, from the live feed to the archive.
