Pretty slick blog from my (new!) colleague Gunnar Morling. Check out GraalVM for native binaries with Kafka
📝 Blogged: "Building a Native Binary for Apache Kafka on macOS"

Quick write-up on using the #GraalVM config from KIP-974 for building a self-contained, native Kafka executable.

How many times does your organization process the same data?

@abellemare.bsky.social introduces a shift left approach, minimizing duplication by processing data once and making it accessible across different use cases. Read here: https://www.infoq.com/articles/rethinking-medallion-architecture/
The End of the Bronze Age: Rethinking the Medallion Architecture
A shift left approach to data processing relies on data products that form the basis of data communication across the business. This addresses many flaws in traditional data processing and makes data more relevant, complete, and trustworthy.

$1.5B for less than $20M ARR? Yikes. Is this a repeat of Databricks buying Tabular?
Speculation is growing that Snowflake is planning to acquire Redpanda—but why? What justifies the rumored high price tag? When you consider market trends, the Snowflake vs. Databricks rivalry, and the AI shift, the rationale starts to become clear. Here’s my take. jack-vanlightly.com/blog/2025/2/...
Why Snowflake wants streaming — Jack Vanlightly
Rumors are swirling that Snowflake intends to acquire Redpanda and many are questioning why and what impact this might have on Confluent. First, let’s remember that these are just rumors and there’s...

S3 (Iceberg) Tables is everything I dreamt of, and more. I blogged some long-form thoughts: meltware.com/2024/12/04/s...

I think we're about to see an explosion of data tools (@materialize.com, @clickhouse.com, @duckdb.org, et al.) learn to write Iceberg tables via S3 table buckets.

The deep goal of bluesky is to decentralize the social internet so that every individual controls their experience of it rather than having it be controlled by 5 random billionaires. Everyone thinks they signed up for a demuskified twitter...we actually signed an exciting and bizarre experiment.

My colleagues at Confluent just put out this video. I'm sharing because it's an homage to Wes Anderson, but also... really cool pastel colors, sets, vintage computers, and a mention to one of my favourite Canadian places, Victoria Island, BC!

They're popping up like mushrooms after a rain!
It's good to see the Kafka API is so widely adopted though, and the de-facto standard.
