QuestDB

QuestDB is an open-source time-series database for high throughput ingestion and fast SQL queries with operational simplicity. It supports schema-agnostic ingestion using the InfluxDB line protocol, PostgreSQL wire protocol, and a REST API for bulk imports and exports.

QuestDB is well suited for financial market data, application metrics, sensor data, real-time analytics, dashboards, and infrastructure monitoring.

QuestDB implements ANSI SQL with native time-series SQL extensions. These SQL extensions make it simple to correlate data from multiple sources using relational and time-series joins. We achieve high performance by adopting a column-oriented storage model, parallelized vector execution, SIMD instructions, and low-latency techniques. The entire codebase is built from the ground up in Java and C++, with no dependencies and zero garbage collection.

Try QuestDB

We provide a live demo provisioned with the latest QuestDB release and sample datasets:

  • Trips: 10 years of NYC taxi trips with 1.6 billion rows
  • Trades: live crytocurrency market data with 30M+ rows per month
  • Pos: geolocations of 250k unique ships over time
Query Execution time
SELECT sum(double) FROM trips 0.15 secs
SELECT sum(double), avg(double) FROM trips 0.5 secs
SELECT avg(double) FROM trips WHERE time in '2019' 0.02 secs
SELECT time, avg(double) FROM trips WHERE time in '2019-01-01' SAMPLE BY 1h 0.01 secs
SELECT * FROM trades LATEST ON time PARTITION BY symbol 0.00025 secs

Our demo is running on c5.metal instance and using 24 cores out of 96.
