## Pick the library that you need

_Simple applications_, like AWS Lambdas or Azure Functions, and scripts, that are **constrained by the size of external
dependencies** or **cannot depend on compiled libraries**, like `pyarrow` (88M), `pandas` (71M), `numpy` (60M),
`libarrow` (41M), `cygrpc` (30M), `libopenblas64` (22M), **need less than 5M of dependencies** (see [detailed report](docs/comparison.md)),
experience the [Unified Authentication](https://docs.databricks.com/en/dev-tools/auth.html#databricks-client-unified-authentication), and **work only with Databricks SQL Warehouses**, should use this library.
