QuestDB is an open-source database designed to make time-series lightning fast and easy.
It uses a column-oriented approach, vectorized execution, SIMD instructions, and a whole array of low-latency techniques. The whole code base is built from scratch, without dependencies, in the name of performance. We are 100% free from garbage collection.
QuestDB implements SQL, and augments it for time-series. It exposes a Postgres Wire protocol, a high-performance HTTP API, and even supports ingestion with Influx Line Protocol. It supports both relational and time-series joins, which makes it easy to correlate data over time. Writes are durably committed to disk, meaning that the data is safe, yet instantly accessible.
