Tonight we are kicking off our favorite event of the year, GraalVM Community Summit 🚀
Looking forward to greeting in Zurich nearly 70 of our core committers, partners, and vendors ❤️

[Jakarta EE @JakartaEE]

☕ Heading to @PortoTechHub on 10 November? Jakarta EE will be there! 
We'll be at booth 10, and @ivar_grimstad would love to chat about Jakarta EE, what's happening in the community, and what's next for enterprise Java.

🤖 @otaviojava will also lead a hands-on workshop, "Implementing AI Architecture Patterns with Enterprise Java”, covering RAG, ReAct agents, multi-agent architectures, and MCP orchestration.

See you in Porto 👉 https://t.co/Iqwdiy4jq8

The real value is that developers can now use a consistent Jakarta NoSQL and Jakarta Data programming model across different time-series databases, reducing database-specific code within applications.

[Otavio Santana @otaviojava]

Transactional systems are designed for preserving consistency, relationships, and state changes, while time-series databases excel at handling continuous data, recent-state queries, historical ranges, and time-based aggregations.

I've never been paid to print Hello World in production. ☕😅

Why compare languages by lines of code?

🏗️ Architecture
🌍 Ecosystem
📜 Open standards
🤝 Vendor independence
🔗 Integrations
That's why I choose Java.

One down, three to go 😎
I will give four Spec-Driven Development workshops this week 😅

Relational databases may remain the system of record, document databases may manage flexible aggregates, key-value databases may provide fast lookups, and time-series databases may handle continuously changing measurements.

Banking systems regularly retain transactional data in relational databases while sending temporal metrics and activity streams to time-series stores for analysis.

🧠 Eclipse JNoSQL expands its Vector API!

🔵 DenseVector → semantic search
🟢 SparseVector → sparse retrieval
🟣 MultiVector → advanced retrieval
☕ 3 types. 1 Vector abstraction.

Upkeeping this model requires ongoing review of principles, active feedback loops, documented architectural decisions, clear exception processes, and leaders willing to reexamine their assumptions

AI can worsen this problem; when teams generate code, add dependencies, or make architectural decisions without shared guardrails, inconsistency and technical debt can spread quickly.

While each addresses specific needs, batch processing is most effective when operations have a defined start and end, involve a known or discoverable dataset, and require controlled execution, progress tracking, restartability, or periodic processing.

[Otavio Santana @otaviojava]

This distinction matters in software engineering, where architectural decisions depend on information moving across teams, technical boundaries, and leadership levels.
