It is designed to be fast, easy to use\nand expressive. Key features are:\n\n- Lazy | Eager execution\n- Streaming (larger-than-RAM datasets)\n- Query optimization\n- Multi-threaded\n- Written in Rust\n- SIMD\n- Powerful expression API\n- Front end in Python | Rust | NodeJS | R | SQL\n- [Apache Arrow Columnar Format](https://arrow.apache.org/docs/format/Columnar.html)\n\nTo learn more, read the [user guide](https://docs.pola.rs/).\n\n## Performance 🚀🚀\n\n### Blazingly fast\n\nPolars is very fast. In fact, it is one of the best performing solutions available. See the\n[PDS-H benchmarks](https://www.pola.rs/benchmarks.html) results.\n\n### Lightweight\n\nPolars is also very lightweight. It comes with zero required dependencies, and this shows in the\nimport times:\n\n- polars: 70ms\n- numpy: 104ms\n- pandas: 520ms\n\n### Handles larger-than-RAM data\n\nIf you have data that does not fit into memory, Polars' query engine is able to process your query\n(or parts of your query) in a streaming fashion. This drastically reduces memory requirements, so\nyou might be able to process your 250GB dataset on your laptop. Collect with\n`collect(engine='streaming')` to run the query streaming.\n\n## Setup\n\n### Python\n\nInstall the latest Polars version with:\n\n```sh\npip install polars\n```\n\nSee the [User Guide](https://docs.pola.rs/user-guide/installation/#feature-flags) for more details\non optional dependencies\n\nTo see the current Polars version and a full list of its optional dependencies, run:\n\n```python\npl.show_versions()\n```\n\n## Contributing\n\nWant to contribute? Read our [contributing guide](https://docs.pola.rs/development/contributing/).\n\n## Managed/Distributed Polars\n\nDo you want a managed solution or scale out to distributed clusters? Consider our\n[offering](https://cloud.pola.rs/) and help the project!\n\n## Python: compile Polars from source\n\nIf you want a bleeding edge release or maximal performance you should compile Polars from source.\n\nThis can be done by going through the following steps in sequence:\n\n1. Install the latest [Rust compiler](https://www.rust-lang.org/tools/install)\n2. Install [maturin](https://maturin.rs/): `pip install maturin`\n3. `cd py-polars` and choose one of the following:\n   - `make build`, slow binary with debug assertions and symbols, fast compile times\n   - `make build-release`, fast binary without debug assertions, minimal debug symbols, long compile\n     times\n   - `make build-nodebug-release`, same as build-release but without any debug symbols, slightly\n     faster to compile\n   - `make build-debug-release`, same as build-release but with full debug symbols, slightly slower\n     to compile\n   - `make build-dist-release`, fastest binary, extreme compile times\n\nBy default the binary is compiled with optimizations turned on for a modern CPU. Specify `LTS_CPU=1`\nwith the command if your CPU is older and does not support e.g. AVX2.\n\nNote that the Rust crate implementing the Python bindings is called `py-polars` to distinguish from\nthe wrapped Rust crate `polars` itself. However, both the Python package and the Python module are\nnamed `polars`, so you can `pip install polars` and `import polars`.\n\n## Using custom Rust functions in Python\n\nExtending Polars with UDFs compiled in Rust is easy. We expose PyO3 extensions for `DataFrame` and\n`Series` data structures. See more in https://github.com/pola-rs/polars/tree/main/pyo3-polars.\n\n## Going big...\n\nDo you expect more than 2^32 (~4.2 billion) rows? Compile Polars with the `bigidx` feature flag or,\nfor Python users, install `pip install polars[rt64]`.\n\nDon't use this unless you hit the row boundary as the default build of Polars is faster and consumes\nless memory.\n\n## Legacy\n\nDo you want Polars to run on an old CPU (e.g. dating from before 2011), or on an `x86-64` build of\nPython on Apple Silicon under Rosetta? Install `pip install polars[rtcompat]`. This version of\nPolars is compiled without [AVX](https://en.wikipedia.org/wiki/Advanced_Vector_Extensions) target\nfeatures.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpola-rs%2Fpolars","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpola-rs%2Fpolars","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpola-rs%2Fpolars/lists"}
