- Polars — DataFrames for the new era
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
- Index - Polars user guide
Polars is a blazingly fast DataFrame library for manipulating structured data The core is written in Rust, and available for Python, R and NodeJS Key features Fast: Written from scratch in Rust, designed close to the machine and without external dependencies
- Installation - Polars user guide
Polars is a library and installation is as simple as invoking the package manager of the corresponding programming language Python Rust pip install polars # Or for legacy CPUs without AVX2 support pip install polars-lts-cpu
- Polars — GPU acceleration with Polars and NVIDIA RAPIDS
With GPU-accelerated Polars, users can expect a performance boost up to 13x compared to Polars on CPU on compute-bound queries This allows users to maintain the same interactive experience as their data processing workloads grow to hundreds of millions of rows
- Polars — Announcing Polars 1. 0
This is a novel design that combines morsel-driven parallelism with Rust’s async state machines This combination leads to a hybrid push pull based engine that benefits from the cache locality, parallelism and NUMA-awareness of morsel-driven parallelism with flexible operator designs that compile down to state machines where the complexity is
- Joins - Polars user guide - GitHub Pages
Polars supports several joining strategies for equi joins, which determine exactly how we handle the matching of rows Polars also supports “non-equi joins”, a type of join where the matching criterion is not an equality, and a type of join where rows are matched by key proximity, called “asof join”
- Polars — Polars Cloud; the distributed Cloud Architecture to run Polars . . .
Cluster side, we have built a distributed scheduler-worker architecture in Rust that can analyze these queries, runs an adapted Polars optimizer and, depending on the query, comes up with a physical plan that scales horizontally or vertically
