Launching Polars Cloud
Polars Cloud is launching at the end of this year for early-stage customers. This platform takes care of the compute infrastructure, so you only need to focus on writing queries.
Whether you're looking to get started with Polars quickly or scale beyond a single machine, sign up for our waitlist today!
Design partner characteristics:
- AWS based or on-premise
- Typical data processing job partitionable up to 1TB
- Real world batch processing use cases
Benefits
Polars is written from the ground up with performance in mind. Its multi-threaded query engine is written in Rust and designed for effective parallelism. Its vectorized and columnar processing enables cache-coherent algorithms and high performance on modern processors.
You will feel right at home with Polars if you are familiar with data wrangling. Its expressions are intuitive and empower you to write code which is readable and performant at the same time.
Polars is and always will be open source. Driven by an active community of developers, everyone is encouraged to add new features and contribute. Polars is free to use under the MIT license.
Built by developers for developers to achieve up to 50x performance
Why use Polars
Polars was benchmarked against several other solutions on the independent TPC-H Benchmark. This benchmark aims to replicate data wrangling operations used in practice. Polars easily trumps other solutions due to its parallel execution engine, efficient algorithms and use of vectorization with SIMD (Single Instruction, Multiple Data). Compared to pandas, it can achieve more than 30x performance gains.

How Polars will
make your life easier
01
Easy
to use
Write your queries the way they were intended. Polars will determine the most efficient way to execute them using its query optimizer.
02
Embarrassingly
parallel
Complete your queries faster! Polars fully utilizes the power of your machine by dividing the workload among the available CPU cores without any additional configuration or serialization overhead.
03
Apache
Arrow
Polars utilizes the Apache Arrow memory model allowing you to easily integrate with existing tools in the data landscape. It supports zero-copy data sharing for efficient collaboration.
04
Close to
the metal
Polars is written from the ground up, designed close to the machine and without external dependencies. This allows for full control of the ecosystem (API, memory & execution).
05
Written
in Rust
The core of Polars is written in Rust, one of the fastest growing programming languages in the world. Rust allows for high performance with fine-grained control over memory.
06
Out
of core
Want to process large data sets that are bigger than your memory? Our streaming API allows you to process your results efficiently, eliminating the need to keep all data in memory.
