Claude stopped talking to our MCP server. Not a bug. MCP shipped 3 transports in 20 months and we spoke the oldest. Rebuilt on Streamable HTTP (Spring Boot 4.1 + Spring AI 2.0). Old /sse still works. https://www.jobrunr.io/en/mcp/ #Java #SpringBoot #MCP #AI #oss

JobRunr 8.8.0 is out. 🚀 ✅ Quieter logs when your database blips ✅ Quarkus: SmallRye now optional ✅ Kotlin 2.4 support ✅ Pro: succeeded-jobs query 640ms → 57ms on MySQL in our 400k-job test jobrunr.io/en/blog/jobrunr-v8.8.0/ #Java #Quarkus #Kotlin #opensource #oss

JobRunr & JobRunr Pro v8.8.0

Quieter logs when your database hiccups, SmallRye now optional for Quarkus users, Kotlin 2.4 support, and a much faster dashboard on MySQL for Pro.

Two reasons to skip JobRunr Spot: your jobs can't safely be re-run, or you need sub-minute pickup. Neither? 62 to 69% below on-demand, measured. The calculator says if your queue fits, even when it's a no. https://www.jobrunr.io/en/spot/?utm_source=bluesky&utm_campaign=spot_beta #Java #AWS #oss

Temporal or JobRunr for durable execution in Java? We built the same workflow in both and measured everything: 1,181 DB commits vs 113,218 for the same 1000 orders. 🧪 Full honest comparison: jobrunr.io/en/blog/jobrunr-vs-temporal/ #Java #Temporal #opensource #oss

JavaClaw has a new home. 🚀 The project moved to its own org, ClawRunr, and top contributor Aref Behboodi steps up as head maintainer. Looking for an all-Java AI agent, or a project to contribute to? https://github.com/ClawRunr/JavaClaw #Java #OpenSource #AIAgents #oss

JobRunr is now on Spring Initializr. 🚀 We could not be prouder. Add JobRunr from the dependency list at start.spring.io, generate, and background jobs are wired into your Spring Boot app. Massive thanks to @starbuxman.joshlong.com & @spring.io 🙏 #Java #SpringBoot #opensource #oss

Last quarter, developers asked our DocsGPT chatbot 1,586 questions. Here are the 5 that kept coming up. A thread. 👇 #Java #SpringBoot #JobRunr #opensource #oss

JobRunr 8.7.0 is out. 🚀 ✅ Plug JobRunr into any JVM framework ✅ Dashboard follows your system theme ✅ Jackson 3 deserializes common Java collections ✅ Pro: batch continuation from within a batch jobrunr.io/en/blog/jobrunr-v8.7.0/ #Java #SpringBoot #Quarkus #opensource #oss

Durable execution is the buzzword of the moment. The real problem it solves: a job charges a card, the pod restarts before the email, the retry replays the whole job and charges the customer twice. 😬 JobRunr already gives you most of it: jobrunr.io/en/blog/what-is-durable-execution-java/ #Java

Every AI agent demo works perfectly. Then you run one in prod and the "remind me every Monday" job silently never fires. 🤖 The LLM is the easy part. Reliable scheduling, retries & visibility are the hard part: jobrunr.io/en/blog/why-ai-agents-need-background-jobs/ #AI #Java #opensource #LLM

JobRunr 8.6.1 is out. 🛠️ ✅ Multi-master election bug fixed ✅ dataVersion mismatches now log ✅ corePoolSize respected everywhere ✅ Micronaut: schedulers on by default https://github.com/jobrunr/jobrunr/releases/tag/v8.6.1 #Java #Micronaut #SpringBoot #opensource #oss

Your AI assistant inventing JobRunr methods that don't exist? 🤖 We shipped the fix. An MCP server giving Claude / Cursor / Copilot live access to every page of our docs. No more hallucinated APIs. https://www.jobrunr.io/en/mcp/ #Java #SpringBoot #MCP #AI #opensource #oss

Running background jobs on Grails? Two gotchas: 🪤 GORM owns the DataSource, JobRunr's auto-config cannot find it 🪤 Groovy closures ≠ Java SAM lambdas New guide: both fixed, plus a runnable demo. jobrunr.io/en/guides/jvm-frameworks/grails/ #Grails #Groovy #Java #opensource

No exception. No alert. Just silence. 😶 That's how distributed Java hides its worst bugs. The AxonIQ team wrote a guest post on our blog about killing them off. https://www.jobrunr.io/en/blog/axon-framework-jobrunr-pro-eliminate-silent-failures-java/ #Java #SpringBoot #opensource #Axon #oss

JobRunr 8.6.0 is out. 🚀 ✅ JDK 26 compatible ✅ Quarkus 3.33 LTS ✅ SQL table validation: 40 min → 5 sec on huge schemas ✅ Faster recurring jobs ✅ Friendlier Fluent API jobrunr.io/en/blog/jobrunr-v8.6.0/ #Java #SpringBoot #Quarkus #opensource #oss

"AI has made scaffolding infrastructure painfully easy. Add a library, copy the sample config, start the app. Problem solved. Background processing is where that habit creates the most false confidence." Great take by Simanta Sarma on implementing JobRunr in Spring Boot #oss #springboot

Building a Java AI agent doesn't mean starting from scratch. Nicholas D'hondt shows how to leverage existing ecosystem tools and connect them smartly. foojay.io/today/how-we... #Java #AI #GenAI

How We Built a Java AI Agent by Connecting the Dots the Ecosystem Already Had

We built an AI agent runtime in pure Java using Spring AI, Spring Modulith, JobRunr, and Spring Events and called it ClawRunr (aka Javaclaw). Here's how the pieces fit together.

Carbon Aware Job Processing now covers the US 🇺🇸 Add a time margin to your job schedule. JobRunr shifts execution to the lowest carbon intensity window. Same job. Less CO2. One config change. Docs: jobrunr.io/en/documentation/configuration/carbon-aware/ #Java #Sustainability #GreenIT #CarbonAware

Carbon Aware Processing

The simple, open-source Java library for reliable background processing. Never lose a job again. Get a full dashboard, automatic retries, and durable job scheduling backed by your existing database.
