Most databases weren’t built for time series.

This one is.

InfluxDB 3 Core is built to handle continuous, high-resolution data with precision and speed

Ingest and query in milliseconds

Sub-10ms access to recent data for real-time systems

Store more data, at lower cost

Compression and object storage cut infrastructure costs on high-volume telemetry

Handle high-cardinality data without breaking

Track millions of unique series with full context and without performance tradeoffs

Process data as it arrives

Run Python directly inside Core for transformations, anomaly detection, and automation – no pipelines required

Download Now

High-Speed Ingest

Ingest billions of series with fewer CPUs and less RAM

Real-Time Querying

Sub-10 millisecond query responses for live and recent data

Unlimited Cardinality

Ingest, transform, and query unlimited time series with unmatched speed and flexibility

Low-Cost Object Storage

Parquet files store more data with less space

Seamless Integration

Integrate with the tools you love via Python-based plugin systems

Native SQL

Analyze data using simple SQL or InfluxQL, a SQL-like language for time series data

Built to adapt. Designed to scale.

InfluxDB 3 Core runs on a diskless, cloud-native architecture for maximum flexibility and simplicity.

Download Now

Easy to operate

No cluster coordination, no rebalancing. Just start a node and go—less to manage, faster to scale.

Run your way

Deploy diskless with object storage (S3, GCS, Azure Blob). Stateless, portable, and built to run anywhere.

Fast from the start

Built-in caching serves hot data directly from memory for real-time queries without ever touching the object store.

FAQ

What is InfluxDB 3 Core?

Open source and free under MIT and Apache 2 licenses, InfluxDB 3 Core is a single-node time series data engine optimized for real-time data collection, high-speed ingest, and sub-10ms queries on recent data.

Is InfluxDB 3 Core free and open source?

Yes. InfluxDB 3 Core is fully open source under MIT and Apache 2 licenses, with no usage fees or telemetry requirements.

When should I choose InfluxDB 3 Core instead of Enterprise or Cloud?

InfluxDB 3 Core is the right choice for developers who want a fast, open source time series engine at no cost—ideal for edge computing, IoT prototypes, single-node production workloads, or any use case focused on recent data rather than long-range historical queries. Upgrade to Enterprise or Cloud Dedicated when you need HA, multi-node, or fully-managed infrastructure.

How quickly can I deploy InfluxDB 3 Core?

InfluxDB 3 Core deploys with a single command and is operational in under a minute, with minimal configuration required to start writing and querying time series data.

Can I upgrade from InfluxDB 3 Core to Enterprise?

Yes. InfluxDB 3 Core is the foundation for InfluxDB 3 Enterprise; you can upgrade in seconds and immediately access high availability, enterprise security, and long-range historical queries without re-architecting your setup.

Where can I deploy InfluxDB 3 Core?

InfluxDB 3 Core runs anywhere: edge devices, on-premises servers, private cloud, or hybrid environments. It uses a diskless architecture backed by object storage (Amazon S3, Google Cloud Storage, or Azure Blob Storage), so compute and storage scale independently.

What are the main features of InfluxDB 3 Core?

InfluxDB 3 Core delivers high-speed ingest, sub-10ms query responses for recent data, unlimited cardinality, low-cost Parquet-based object storage, and native support for both SQL and InfluxQL.

How does the InfluxDB 3 Processing Engine work in Core?

The InfluxDB 3 Processing Engine lets you run custom Python scripts directly inside the database, transforming and enriching streaming data in real-time, without requiring external services, Lambda functions, or separate pipeline infrastructure.

What technologies is InfluxDB 3 built on?

InfluxDB 3 is written in Rust and built on the FDAP stack: Apache Flight, DataFusion, Arrow, and Parquet. This combination enables efficient columnar time series storage and query execution at any scale.
