Distributed systems, s/w craftsmanship, concurrency & parallelism. Maybe cinema, coffee & cycling too. Any resemblance to real opinions, is purely coincidental

[Konstantine Karantasis @karantasis]

Very honored and excited for this new chapter. Warm thanks to everyone!

[Apache Kafka @apachekafka]

We are happy to announce that @karantasis accepted our invitation to become an Apache Kafka committer.

Join us to congratulate him!

[Konstantine Karantasis @karantasis]

@asc89 Just do as it says. Did you like it?

[Konstantine Karantasis @karantasis]

Ok, this is cool! 🐅🦁🐘

🦒 Wildlife monitoring with @apachekafka!🐘 As part of Confluent #Hackathon ’22, @SimonAubury built a project using a Raspberry Pi, camera, Kafka, & @KafkaConnect to identify animals and understand population trends over time. Read about his project 👉 https://t.co/Gjk4SPsMnV

"More importantly though, data streaming is about connectivity", well-written and insightful thread overall. Highlighting this quote because I'm a bit biased too 😀

1. Thoughtworks notes that "Kafka continues toward its status as a de facto standard." noting that Kubernetes, Kafka, and the CSPs are becoming stable layers in the next gen stack and churn around alternative platforms seems to have waned. https://t.co/ax39zAxBnz

@tlberglund @apachekafka Great video and scenery @tlberglund! Cinematic by all accounts I'd dare to say.

[Konstantine Karantasis @karantasis]

Definitely a highlight of this summer for me and a very rewarding experience to work with the Apache Kafka community to release version 3.0.0

[Apache Kafka @apachekafka]

Apache Kafka 3.0 is released! 🎉

Another step closer to remove ZooKeeper dependency. And of course many other improvements, bug fixes, and new features.

Thanks to 141 contributors and our RM @karantasis!

1. A quick reflection on Confluent's IPO today and the journey so far (a thread!).

[Konstantine Karantasis @karantasis]

A fully managed connector of my team at the forefront of the partnership between two of the most dynamic software companies out there.

[Confluent @confluentinc]

Confluent and @elastic are excited to work together to make it easier than ever to integrate @apachekafka and Elasticsearch with the fully managed Elasticsearch Sink Connector. Read more from Confluent CEO @jaykreps on our expanded partnership: https://t.co/dBxw8ClppL

@DanielOsvath wrote about his recent experience with Kerberos and this tutorial can save some of us a lot time during troubleshooting. Good security is an integral part of every decent data integration solution and lots of Kafka connectors support Kerberos authentication already.

[Confluent @confluentinc]

Kerberos authentication is widely used in today’s client/server applications; but getting started without experience can be a challenge! @DanielOsvath provides a simple setup for a Kerberos test environment with SSH in today’s blog. Check it out: https://t.co/Nijtow5m7f

@criccomini Side-effect of autogenerated configs. `null` is mentioned in the source connector overrides but in the worker configs the default is correct https://t.co/kWdCwKNHF9
Created https://t.co/AfoGmf0dnG to fix

[Konstantine Karantasis @karantasis]

@criccomini I totally agree with you on that. It's a general default but with surprising side-effects. I've suggested documentation notes/additions at a minimum and we should reconsider it as a default, indeed.

[Konstantine Karantasis @karantasis]

@criccomini The converter might be crashing or spending too much time on non-UTF encodings. I've noticed abnormalities with other (less popular) encodings in strings.

[Konstantine Karantasis @karantasis]

@criccomini My benchmarks have revealed that ByteArrayConverter is 4x-5x faster and StringConverter 2x-3x (with lower CPU), so if you can use these 👍. But if none of these converters fits your needs maybe a custom implementation (this class is configurable) could offer peace of mind.

[Konstantine Karantasis @karantasis]

@criccomini SimpleHeaderConverter is meant to be general, but as its name reveals it's also simple. In high volume it's general approach of inferring types comes with a higher CPU cost.

[Konstantine Karantasis @karantasis]

@apachekafka I'm thrilled. Thank you all! It's an honor and a great responsibility. I'm really looking forward to serving the Apache Kafka community and its innovative technology on this new role!

[Konstantine Karantasis @karantasis]

@MatthiasJSax Haha. You have to google the whole thing: https://t.co/DygaZNXryA

[Konstantine Karantasis @karantasis]

Deja vu all over again :) And an opportunity for a live QnA!

[Confluent @confluentinc]

Join us tomorrow for a technical deep dive on Kafka’s load balancing feature. We’ll discuss the proposition of Incremental Cooperative Rebalancing as a way to alleviate stop-the-world and optimize rebalancing in Kafka APIs. Register here: https://t.co/6Gi8RGD0hv

[Konstantine Karantasis @karantasis]

@gwenshap Lol. And while I was thinking... nothing can stress me out before the talk at this point 😂

[Konstantine Karantasis @karantasis]

@ewencp @sderosiaux @sderosiaux we are having an online talk on the subject again tomorrow. Feel free to join and ask questions if you have time: https://t.co/fou59t98QE

Parquet support for @confluentinc S3 sink connector got merged. Highly anticipated, it was accomplished in one of my favorite ways: as a top quality community contribution! Thanks Tony Wei and Ryan Eakman! Available from source on github now, will ship with Confluent Platform 5.4
