DuckDB hype man, MotherDucker (I work at MotherDuck!), SQL nut, Pythonista, reluctant JS dev
The Register published a report on DuckLake v1.0 and cited our recent post: > In a blog post accompanying the 1.0 launch, Pedro Holanda, DuckDB Labs principal engineer, said the company's benchmark shows 926× faster queries and 105× faster ingestion when compared to Iceberg, the open table format.

Are you streaming into your Lakehouse? Traditional formats suffered with the “many small files” problem — OLAP engines merge them reactively with long jobs. ⏳ DuckLake takes a proactive path: Data Inlining + async flush to parquet while always keeping data queryable ⚡

How many 6 year old databases get 3x faster sorting??? When it was already world-class??? Amazing stuff from DuckDB!
DuckDB@duckdb.org · 10mo agoWe published a new deep dive by Laurens Kuiper, who recently redesigned DuckDB's sort. One data point: ordering the TPC-H SF100 lineitem table with the memory limit set to 30 GB is 3× faster in DuckDB v1.4 than in v1.3. Read more at duckdb.org/2025/09/24/s...

v@avi.im · last yr.Published a new post: "PSA: SQLite WAL checksums fail silently and may lose data" This is a follow up to my previous posts. When SQLite encounters checksum failures in WAL, instead of raising an error, it drops all subsequent frames; even if they are not corrupt. It's not a bug
