InfluxDB 3 Core: a complete rewrite designed for speed and simplicity

InfluxDB 3 Core is a significant update to the popular time series database, designed to enhance speed and simplicity, as explained by Paul Dix, Co-founder and CTO of InfluxData, during GrafanaCON 2025. This new version addresses long-standing user requests by introducing features such as unlimited cardinality, SQL support, and the separation of compute and storage, achieved through a comprehensive rewrite from Go to Rust. InfluxDB 3 Core simplifies the user experience with a one-command installation and enables advanced data processing with an embedded Python engine, while its diskless architecture allows for cost-effective, durable storage solutions. The database caters to diverse use cases, from server network monitoring to sensor data across various industries, distinguishing itself by supporting multiple column types and schema-on-write capabilities.
