QuestDB is an open-source time-series database for high throughput ingestion and fast SQL queries with operational simplicity.
QuestDB is well-suited for financial market data, IoT sensor data, ad-tech and real-time dashboards. It shines for datasets with high cardinality and is a drop-in replacement for InfluxDB via support for the InfluxDB Line Protocol.
QuestDB implements ANSI SQL with native time-series SQL extensions. These SQL extensions make it simple to filter and downsample data or 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, C++ and Rust with no dependencies and zero garbage collection.
QuestDB supports schema-agnostic…
