why .parquet dominates modern data engineering
This video explains why the Parquet file format has become a dominant standard in modern data engineering by using columnar storage to improve speed and reduce file size compared to traditional CSV formats. It details key technical features like compression, encoding, and predicate pushdown that allow for significantly more efficient data retrieval and storage for large-scale analysis.
Parsing JSON at tens of gigabytes per second… in Python
Free-threaded Python 3.14 can push JSON parsing into the tens of gigabytes per second when fastsimdjson spreads work across many cores and avoids eagerly materializing Python objects. On a 64-core machine, Lemire reports throughput around 66 GB/s, showing how dramatically multithreaded parsing can scale when Python’s GIL is no longer the limiting factor.
A Clean Way to Implement Undo in Python
This video explains how to implement the Memento design pattern in Python to handle state restoration and undo functionality without breaking encapsulation. It demonstrates a clean, modern approach using frozen data classes, protocols, and generics to manage state snapshots independently of application logic.
