Python 3.14 can finally run Python threads in parallel — but native extensions don’t get the speedup for free. At PyData Amsterdam this Friday, I’ll share what it took to make a C++-backed Python extension actually benefit from free-threading: what broke, what surprised us, and

New: chDB as a Postgres extension. Import/export from S3, GCS, Azure, HTTP, and local files — in the formats ClickHouse already supports (Parquet, Arrow, ORC, JSON, Avro, and more). COPY and CREATE TABLE ... copy_from just work. Helper process on demand, not an engine living

Congrats to Hannes and @mraasveldt Embedded analytics is a category people take seriously now, and DuckDB is the one that opened that road. We met last year and talked for a long time — I still remember that conversation. Wishing the project a long life in the open, and the two
