Python, rust and arrow for data processing
Paulius Venclovas

Python struggles with heavy data loads. Rust offers speed, and PyO3 makes bridging the two seamless. This talk shows how to build a shared Rust core to avoid code duplication. I will also cover using Apache Arrow for zero-copy data sharing and removing serialization costs entirely. Discover how this stack enables high-performance data processing in Python and Pyspark
