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 ⚡
I think we might all perish....
How's the async io boost looking?
Welcome to the flock!!!
How many 6 year old databases get 3x faster sorting??? When it was already world-class??? Amazing stuff from DuckDB!

We 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.

I've been leading the data infrastructure efforts at my job (I used to work as a Data Engineer in big tech) and the stack we've landed on is so enjoyable to work with.

@dagster.io - Orchestration
@duckdb.org - Database
@motherduck.com - Data Warehouse/storage

Laurens Kuiper from @duckdb.org presented DuckDB's new memory assignment policy to run multi-join pipelines out-of-core with gracious performance degradation when join hash tables increasingly do not fit in RAM.

A well-attended and -delivered talk!

Bad news: we had to postpone today's episode.

Good news: @tylerhillery.com has a great blog entry that features some of the Oxide and Friends back catalog you might have missed!
I wrote about why I believe the Oxide and Friends podcast will have a greater impact on their mission to change computing forever than their rack scale computer

Ah, so you are saying you hit a bug on the first execution? If you can reproduce it, we love bug reports!!
