Interesting Links in Data Engineering: October 2026

All treats, no tricks this month ;) A bunch of new releases including DuckDB 2.0, Kafka 4.4, Iceberg 1.12, and Flink CDC 3.7 Lots of stream processing stuff - deduplication with Flink SQL, republishing a treasure-trove of Kafka Streams articles A lovely thought-provoking piece from Joe Reis ("the pendulums of data") which puts the forever-changing 'best way' to do data architectures in perspective Illustrated introduction to CDC Semantic layers, context layers, context engineering…confused yet? I was. A very nifty tool for working with Parquet A narration of Postgres history … and lots more! h
