We are excited to announce our plans for two major new initiatives for the MySQL ecosystem: 🔹 Vector Search & Indexing 🔹A dedicated MySQL Binlog Server! https://bit.ly/4rlTMLM

MongoDB licensing costs spiraling out of control? 😵‍💫 There's a better way. Join our 30-minute on-demand webinar to discover how Percona Server for MongoDB delivers enterprise-grade features without vendor lock-in. Watch now & take back control of your data infrastructure! 🔗 https://bit.ly/43MJjyK

This @czjug.bsky.social ☕ meetup at @sentinelone.com turned out to be absolutely amazing 🌟 and we had the most pople show up since before covid 🎉. Seems the community loves hardcore stuff like profiling ‼️

Another packed Java ☕️meetup at Sky Czech Republic.

Get ready for another #CZJUG ☕ meetup. And this one is going to be a banger 🥊. Three frameworks ⚙️, three champions 👑, one result 🏆. Fighting arena and medical services 🚑 will be provided by Tricentis. www.meetup.com/czjug-prague...

Cross-cluster MongoDB on Kubernetes, simplified. See how the Percona Operator connects two GKE clusters with Multi-Cluster Services. https://bit.ly/4pn6SHP

Search that understands meaning instead of just words. This new Red Hat blog shows how EDB Postgres AI and Red Hat OpenShift AI work together to power semantic and visual search for fashion—and any catalog where “looks like” matters more than exact wording: developers.redhat.com/articles/202...

🛫 to the madness of London 🇬🇧on strike🚇. Fortunately the #IcebergMeetup should make up for it.

The #DataGeeksMunich meetup was great! First a very well framed talk about process mining, and then Ismail Simsek showcased his @debezium.bsky.social Iceberg consumer. Always nice to see our community grow the project further🚀

Some hardcore 🔥Java ☕️ stuff from the legendary performance geek Jaromir Hamala at #bJug about #QuestDB. Just a single post, this requires attention 🧠.

Štěpán Šindelář is demonstrating live why ☕️Java ❤️ Python🐍 at yet another @czjug.bsky.social meetup about @graalvm.org and #GraalPy

Turns out @duckdb.org is a Protocol masquerading as a Database. Checkout our CEO and Co-founder, @avery.summer.io's post about DuckDB and its implications on the future of data products.

In case you are still not sure 🤔 about going. Today's @czjug.bsky.social ☕ event is also sponsored by @jetbrains.com and we will have some goodies 🚀 for you. ⭐ Also big thanks to our other sponsors Sky Czech Republic 🍕 and Oracle 🏢

Just a reminder ⏱️ that the next #CZJUG talk 🎙️ about Java ☕ and Python 🐍 is happening tomorrow! As usual, after the talk we will continue chatting over some 🍻. www.meetup.com/czjug-prague...

Next @czjug.bsky.social about ☕ and 🐍 is this just behind the corner (www.meetup.com/czjug-prague... ), however if you unfortunately happen to be in Brno that week and don't want to miss on #JVM fun, you can visit our friends at #KotlinServerSquad www.meetup.com/kotlin-serve...

@duckdb.org is at it again 🚀. I'm really curious how this will be positioned against #Iceberg and @deltalakeoss.bsky.social. The ease of use and low barier of entry makes this very relevant IMHO 🦆🦆🦆 ducklake.select

🚀 @czjug.bsky.social events continue. Join us at #Oracle Prague offices to learn 💡 from Štěpán Šindelář about bridging modern Python 🐍 and the JVM ☕ ecosystem with #GraalPy and @graalvm.org 🍕 at the venue and discussion over 🍻 afterwards . #JUG #GraalPy #Java #Python #JVM #Prague

Structured data is very sneaky! Just ask your favourite LLM. 1GB of text = ~250M tokens 1GB of structured trades = ~1B tokens That’s 4× the token cost for less semantic richness. Our new agentic friends have many capabilities, chewing structured data not among them. questdb.com/blog/why-ai-...

After some minor technical difficulties we are back for the second talk of @czjug.bsky.social and #KBTechMeet with Haoyi Li talking about (possibly) better future for java build tools.

Another @czjug.bsky.social in progress together with #KBTechMeet. Starting with Jirka Pinkas and his talk about DDD.

Interesting move and a new study programme from @vut.cz. Right target audience and decent course composition, the price is IMHO also very acceptable. Although some legislature/law centric courses should be mandatory. Good direction overall! www.utko.fekt.vut.cz/master-scien...

For the next event @czjug.bsky.social is partnering with Komerční banka and #KBTechMeet. There will be TWO talks 🎉 - Haoyi Li: 🎤 Java ☕ build tools and their potential for improvement 🚀 - Jirka Pinkas: 🎤 Advantages of Domain Driven Design 🛠️ www.meetup.com/czjug-prague...

Peter Malina talking about agent🤖 development in Go with Genkit @ #gophercamp #Brno

Martin Ladecký walking us through the development of #Loono ‘s Preventivka app 📱 at yet another @czjug.bsky.social meetup ☕️. This time hosted by Commerzbank Czech Republic . Thank you 🙏🎉

Yay! We are now part of the @commonhaus.org family! kroxylicious.io/commonhaus/2...

So looking forward to this... IMHO This will be a fresh wind for Kafka adoption aiven.io/blog/diskles...

🚀 Introducing **Bauplan** A serverless, code-native platform for building data and AI pipelines — directly on your object store. No clusters. No notebooks. No GUI based workflows. Just Python + SQL + S3. 👉 www.bauplanlabs.com/blog/hello-b...

Only few days left, reserve your spot for next Tuesday and come to learn about mobile development 📱 of #loono app.

Commonhaus is 1! 🎂 14 projects, solid foundations, and more on the way. If you believe in light governance, shared care, and thoughtful support for open source, come see what we’re building. www.commonhaus.org/activity/253...

Great read about developing 🛠️ K8s controllers! ahmet.im/blog/control...

Another @czjug.bsky.social ☕ event! Martin Ladecky will give us a deep dive into design and development 🛠️ of mobile app 📱 for #loono. PS: If you never heard of Loono (www.loono.cz) , check them out and make sure you stay healthy 💪 #boobsandballs #yourheartforlife #allgooddownthere #feelinggood

Was a pleasure to have you @lefredbe.bsky.social !!!

Possibly the first Agentic framework that might be suitable for production. Could it be because it actually builds on top of real microservice solution and thus has logging, observability, scaling and async communication build in? www.cncf.io/blog/2025/03... PS: Waiting for #knative response

Time for yearly re-read of this masterpiece is here!

Chapters 1–7 of the second edition of Designing Data-Intensive Applications are now available in early release (sorry, O'Reilly subscribers only at this point). Among other changes, you may notice that we now talk about “sharding” rather than “partitioning” www.oreilly.com/library/view...

A reminder that this @czjug.bsky.social talk is happening next week 🚀 at Keboola 🐙. There will be food, drinks, and lots of MySQL!

AI agents 🤖 are autonomous micro services 🌐. Their adoption will face the same technical obstacles -- monitoring👁️, orchestration👥, auto discovery 🔍(of tools and other agents). Middle-ware and infra still required. Hopefully we won't forget good design practice before the hype wave calms down.

🚀 Join us for an exciting hashtag #CZJUG talk! This time, it's not just for #Java enthusiasts ☕—we’ve got something for all tech lovers! Frederic Descamps aka @lefredbe.bsky.social , a MySQL evangelist @Oracle, will share his top tips and tricks to level up your database game💡 This time at Keboola 🐙

#ApacheFlink CDC 3.3 has been released! Highlights include new transforms and pipeline connectors for Flink CDC, improvements to the CDC connectors, and support for Flink 1.19+. flink.apache.org/2025/01/21/a... #dataBS

Migrating to #OrbStack was one of the best QOL changes in my dev environment in a while. I had to migrate back to docker from Podman, however this thing is so much better than DD or PD. I will be happy to part with those $8/month.

📣 If you don't have a complete mastery over virtual threads or feel like having some revision 🧠 , definitively go grab one of the remaining seats. The "Brief history of Virtual Threads in Java" talk by @kec.bsky.social is Today ⏰! Entire @czjug.bsky.social is looking forward to see you all.

📺 "CDC & Kafka: How Slack Transitioned to CDC with #Debezium & #Kafka Connect" Great talk by Joseph Thaidigsman and Tom Thornton about the adoption of @debezium.bsky.social at Slack. Tom is also the most active contributor of the Debezium connector for Vitess! www.youtube.com/watch?v=ZCkJ...

Another @czjug.bsky.social meetup is already scheduled🚀. This time we will be hosted by Oracle and our very own @kec.bsky.social will talk about how virtual threads 🧵 became part of Java ☕!

📢 #Debezium 3.0.5 Final is out!

Gerrit Grunwald aka @hansolo.eu from @azulsystems.bsky.social will come to #Prague #czjug event on Dec 9. His talk is about CRaC(Coordinated Restore at Checkpoint). All #Java geeks interested in snapshotting running JVM are welcome!
