Polars Data Engineering in Python: Building Fast Data Pipelines with Arrow and Lazy Evaluation (Paperback) (ISBN-13: 9798176642278)

Unlock peak performance in Python data processing with the power of modern, multi-threaded DataFrames.

As datasets grow into millions of rows, traditional single-threaded Python tools hit severe memory bottlenecks and slow to a crawl. Polars Data Engineering in Python provides a clear, practical roadmap to building lightning-fast, production-grade data pipelines using the Polars library.

Designed for data engineers, scientists, and analysts who need to break through Python's speed limits, this hands-on guide shows you how to write clean, vectorized code that executes at native C/Rust speeds.

• Arrow-Native Architecture: Harness Apache Arrow's columnar in-memory format for zero-copy operations and reduced memory footprint.

• Lazy Evaluation & Query Optimization: Master query planning to automatic optimize filters, projections, and joins before execution.

• Parallel Processing: Utilize all CPU cores automatically without managing complex concurrency, threads, or locks.

• Streaming & Out-of-Core Execution: Process datasets larger than your machine's physical RAM seamlessly.

• Real-World Integration: Connect Polars smoothly into existing Python ecosystems, SQL workflows, and data warehouse pipelines.

Whether you are migrating existing workflows or architecture from scratch, this book gives you the exact patterns and techniques needed to build resilient, high-performance data pipelines.

Upgrade your data infrastructure and accelerate your Python workflows today.
