The next #PyData #Helsinki #meetup is on 19 March 2026 at Elisa, Ratavartijankatu 5.

On the menu: optimisation problems in electricity markets, a deep dive into #DeltaLake read performance without a cluster, two lightning talks, and an intro to Data & AI at our sponsor Elisa.

And of course our already traditional quiz, where the main challenge is understanding how answers are scored.

My most frequently asked question in 2025 was: how do you design for
high-throughput ingestion with #deltalake

Over the last week I took the time to write down exactly how I design for throughput in this blog post: https://www.buoyantdata.com/blog/2026-01-02-design-for-throughput.html

🎉 Excited to Share a Milestone!

I’m thrilled to announce that I’ve successfully earned the Databricks Academy Platform Administrator accreditation! This achievement validates my ability to manage and administer the Databricks Lakehouse Platform effectively.

Looking forward to continuing to explore advanced analytics, AI/ML integration, and generative AI workflows within Databricks.

kafka-delta-ingest was the project that spawned the development of #deltalake for #rustlang, also known as delta-rs.

Last week I decommissioned the last of those processes. I have since made our
ingestion even cheaper but kafka-delta-ingest will always hold a spot in our history

Tomorrow at 7am PT (14:00 UTC) I'll be doing some #deltalake hacking with some other 🦀 folks on #deltalive!
