I just publish it, hope it'll help: dev.to/fb64/duckdb-...

DuckDB + Iceberg: The ultimate synergy Introduction Apache Iceberg and DuckDB have established themselves as key players in data...

With the latest release of @duckdb.org 1.4, I explored the ultimate synergy with Iceberg. Check out this full open-source example of reading and writing to an Iceberg table using DuckDB, Apache Polaris, and MinIO 🦆🧊🚀
#apacheIceberg #apachePolaris #MinIO
dev.to/fb64/duckdb-...

I created an Iceberg table from some NY taxi parquet files then I succeed to perform some queries on it. I don't dive into more complexe exemples yet , but it seems to work. I'll try write a small post about it next days.
It's really promising to combine @duckdb.org and Iceberg !

I just give it a try and it's working (with basic example), I used Polaris + Minio + DuckDB 🦆 🚀
by following "Setup" of : polaris.apache.org/in-dev/unrel...
I had to create a new namespace to the provided quickstart_catalog before succeed to create a new table in DuckDB.

📈 DuckDB 1.4.0 is out! This is our first LTS release which comes with *one year of community support*. It also supports database encryption, the MERGE SQL statement and Iceberg writes.

Ping @toulousejug.bsky.social

Vu à Toulouse à la minute près ! Merci @citedelespace.bsky.social pour les infos précises 👍

Will it work with ducklake tables ?

Is duckdb killing the game of open table format ?

Parquet Bloom Filters in DuckDB DuckDB now supports reading and writing Parquet Bloom filters.

Remind me a good article on how DuckDB use Bloom filters to speed up queries on parquet files: duckdb.org/2025/03/07/p...

antix Linux Ram/CPU consumption

Slack RAM consumption

I recently installed @antixlinux.com.web.brid.gy on a old computer... It works pretty well and take only a bit more than 100Mo of RAM, meanwhile on my modern laptop Slack App take more than 500Mo 🙃

Second talk, Florian Bernard nous explique comment sécuriser son application sans toucher à son code !

Why your multiprocessing Pool is stuck (it’s full of sharks!) On Linux, the default configuration of Python’s multiprocessing library can lead to deadlocks and brokenness. Learn why, and how to fix it.

Today I learned (or I confirmed) that 🐍 Python really sucks at multi-threading/processing :
- ThreadPoolExecutor not execute your code in parallel (due to the GIL) 😞
- ProcessPoolExecutor could get stuck due to plain forking process (by default) 🛑
This great article save my day (and my code) 🙏

All projects around Apache Arrow ecosystem are really cool. DataFusion is not yet as popular as DuckDB or Polars but is really promising !

Glad to have contributed to the @langchain4j.dev project by adding support for @duckdb.org as an embedding store.
Let's give it a try: docs.langchain4j.dev/integrations...

Après 2-3 jours sur BlueSky: finalement c'est Twitter mais plus rapide ⏩, sans pub 📢🚫et une app open source👨‍💻...
Ça me paraît presque trop beau pour être vrai 😅
