@opensearch.org was named a Leader and Fast Mover in the 2025 GigaOm Radar for Vector Databases 🏆 My #OpenSearch report highlights: ✅ Platform play ✅ Search variety ✅ Business criteria ✅ Security And I'd add - it's OPEN SOURCE @linuxfoundation.org!! opensearch.org/gigaom-radar... #gigaom #vectorDB

#Observability, #AIML and #GPU are major themes in this week's #KubeCon Europe talks. More interesting is the synergy between these themes in talks. Cool, as #OpenSearch V3 has new capabilities combining all these themes 😁 linkedin.com/feed/update/... #OpenSearchAmbassador @opensearch.org #KubeConEU

KubeCon 2017 was held in Berlin (second KubeCon Europe) And it'll come back to Berlin in 2028. #KubeCon #KubeConEU #Berlin

Only 1️⃣ week to Observability Day — still my favorite #KubeCon co-lo! There’s a lot happening in the @opensearch.org, and I've got only a few minutes on stage for project update 😅 For the full story, come by the #OpenSearch booth at #O11yDay and the main #KubeConEU See y'all in Amsterdam!

Celebrating 20 years of #AWS 🎂🎉 And my first year along for the ride, with the #opensource team 😁 (ICYMI see comments) I might be a new employee, but I've been in the #AWS ecosystem for way longer. Even dug up a 👕 with the original logo. Happy anniversary! 🍾 www.linkedin.com/feed/update/...

You already know that you can visualize your metrics from #Prometheus in #OpenSearch Dashboard's Discover Metrics experience (if not, check the comments). But what if we could add some #AI sauce for #anomalyDetection & #forecasting? New RFC @opensearch.org github.com/opensearch-p... @prometheus.io

Do you use Apache #Iceberg -based lakehouse as your source of truth, and need full-text search and real-time dashboards over that data? Why not combine it with #OpenSearch? Check out this new RFC for an iceberg source plugin to @opensearch.org: github.com/opensearch-p... #OpenSearchAmbassador

📢 a new patch for @opensearch.org 2.19: OpenSearch and OpenSearch Dashboards 2.19.5 includes important bug fixes, infrastructure, documentation and maintenance updates. ◽ Release Notes: github.com/opensearch-p... ◽ Download: opensearch.org/artifacts/by... #OpenSearch #OpenSearchAmbassador #release

OpenSearchCon China 距离上海会议仅剩一周时间! 🇨🇳 #OpenSearchCon China is just one week away in Shanghai! 17-18 March @opensearch.org community comes together to discuss #OpenSearch, Apache Lucene, and #opensource #search, #observability and #analytics. 👉 www.lfopensource.cn/opensearchco... #OpenSearchAmbassador

310% throughput increase and 300% latency reduction! Great work by the AWS #opensearch engineers with bulk SIMD brings these performance gains in @opensearch.org 's vector search 👏 And it's all #opensource under @linuxfoundation.org 🤩 opensearch.org/blog/acceler... #vectorDB #OpenSearchAmbassador

Building AI agents is easy. Knowing if they actually work? That’s the hard part. We just released Agent Health, a new #opensource tool @opensearch.org that helps you trace every agent decision, evaluate accuracy & hallucinations, and track token usage & cost. opensearch.org/blog/opensea... #aiagents

📢 I'm excited to share that @opensearch.org has launched a dedicated Observability Stack! As someone deep in both #OpenSearch and #observability, I think this launch marks a significant milestone: #OpenTelemetry -native #opensource platform for full-stack o11y 🔗 observability.opensearch.org 🧵

“If your collectors are tied to a specific backend, it’s not #OpenTelemetry anymore — it’s just telemetry” With all the vision of open #observability behind OTel, is the collection layer still a lock-in risk? Check out the latest @openobservability.bsky.social 🎙️ ep. 👉 medium.com/p/e00f219f7460 🧵

📢 We have a Technical Advisory Group (TAG) for #Security in @opensearch.org! The TAG already has diverse participation from AWS, @eliatra.bsky.social, Uber and Aiven. If you're also interested in #OpenSearch and Security, don't miss out the new security TAG! github.com/opensearch-p...

Apache Solr next major release 10.0.0 is out. Congrats to the maintainers and all involved 👏 solr.apache.org/news.html#ap... #opensource #search #solr

At last week's #Observability TAG meeting, we discussed a proposal for a unified UI within @opensearch.org Dashboards that displays alerts from @prometheus.io #Alertmanager and #OpenSearch Alerting side-by-side. Check out the RFC and chime in with your thought: github.com/opensearch-p...

📢 Apache Lucene 10.4.0 is out! ✅ Many lucene queries should see a performance improvement of 10-15% ✅ A new scalar quantized format for dense vectors and knn search. #Lucene sits at the heart of so many #search platforms, including @opensearch.org, that stand to benefit from this release.

Saturday morning I woke up to sounds of alarms. Grabbing the children from their beds and running in pajamas to the bomb shelter. Since then our lives have been swinging between these alerts on rocket, missile and drone attacks www.linkedin.com/feed/update/... #LionsRoar #EpicFury

W00t I got my #OpenSearchAmbassador swag pack! Just in time for next week's trip to @socallinuxexpo.bsky.social and to @javaland.bsky.social Thanks @opensearch.org and @linuxfoundation.org for the cool 🎁

Can't wait to to have a great ride at #JavaLand! 🇩🇪 #OpenSearch sucht nicht mehr nach Wörtern, sondern nach Bedeutungen. 🔍 Join me to learn about #vectorDB search and about the @opensearch.org #opensource Project See you 11 March @javaland.bsky.social 🎡 👉 meine.doag.org/events/javal...

As #AI systems move into prod, I keep seeing the same pattern: traditional #observability isn’t enough. We’re no longer just measuring latency and errors — we’re dealing with model drift, hallucinations, semantic quality, token cost, non-deterministic behavior. horovits.medium.com/observabilit...

Half a year ago I was at RAI Amsterdam for Open Source Summit Europe. Next month I'll be back there for hashtag#KubeCon Europe 🇪🇺, the flagship event @cncf.io, and bringing the @opensearch.org gang with me. See you 23-26 March! 🚲 🇳🇱 #opensource #cloudnative #cncfAmbassador #OpenSearchAmbassador
