Scalable datastore for metrics, events, and real-time analytics
InfluxDB Core is a powerful database designed for the efficient collection, processing, transformation, and storage of event and time series data. It’s particularly suited for applications that require swift real-time ingestion and rapid query responses, making it an excellent choice for user interfaces, monitoring, and automation. Common scenarios for usage include monitoring sensor data, server performance, application analytics, and even financial market tracking. The emphasis on real-time data is especially beneficial for dashboards and interactive applications that rely on instant responses.
With the recent launch of InfluxDB 3 Core, which became generally available on April 15, 2025, users can expect significant improvements and new features aimed at enhancing performance and compatibility across various use cases.
Diskless Architecture: InfluxDB supports an innovative diskless architecture, allowing for object storage or local disk deployment without dependencies, enhancing performance.
Fast Query Response Times: The database boasts exceptional query speeds, with last-value queries returning results in under 10ms and distinct metadata queries in approximately 30ms, crucial for responsive applications.
Embedded Python VM: Users can utilize an integrated Python virtual machine to create plugins and triggers, expanding the functionality and adaptability of the database.
Parquet File Persistence: Support for Parquet files ensures efficient data storage and quick access, further optimizing data handling and retrieval.
Compatibility with Previous Versions: InfluxDB 3 Core maintains compatibility with InfluxDB 1.x and 2.x write APIs, as well as the InfluxQL query API, making migration smoother for existing users.
SQL Query Engine: The inclusion of a SQL query engine with support for FlightSQL and HTTP query APIs allows for enhanced data manipulation and integration with other systems.
Regular Updates: The development team plans to implement monthly point releases and necessary patches, followed by quarterly updates, ensuring the database remains robust and current with user needs.
InfluxDB Core is an invaluable tool for anyone needing to harness the power of real-time data, providing a comprehensive feature set that supports a diverse range of applications.
