🎤 In this interview, Kris Freedain, #OpenSearchAmbassador and Community Manager of the #OpenSearch project, speaks with Nicholas Adams at TI Tokyo 🇯🇵 during his first-ever OpenSearchCon in Japan, sharing his experience and reflections on the OpenSearch community 🤝
#OpenSearch
I joined InstaBlinks podcast to talk about vector search, difference from lexical search, and how the @OpenSearchProject facilitates both in a hybrid model.
Thanks NetApp Instaclustr for having me!

The syslog-ng 4.11 release is right around the corner. Thousands of automatic tests run before each merge, but nothing can replace real-world hands-on tests. So help us testing Elasticsearch / #OpenSearch data-streams, #Kafka source, and much more!

What a fantastic day at #CHAOSScon 😀
Thank you to everyone who showed up for my Guided Discussion / BoF: Building a Global #OpenSource User Group Program. I really enjoyed our conversation. #OpenSearch #OpenSearchAmbassador
💡 Did you know Atlassian uses OpenSearch across multiple use cases including Jira, Rovo, operational data, and user search?

We Want Your Feedback!
Hey #OpenSearch community, we have drafted an RFC (security/#5814) to improve the experience when using various OpenSearch functions with users having limited privileges.

OpenSearch - база даних, яка не дуже шанує свої дані
От цікаво ж, що в OpenSearch/ElasticSearch головним змістом бази є індекси, а не дані.
Дані, тобто документи, можна взагалі не зберігати. Є режим, коли документи не зберігаються, а реконструюються з індексів - synthetic _source. Або взагалі ніяк не зберігати — повертати тільки ID. Пішло це, як я розумію, від того, що ElasticSearch починалася як рушій пошуку для іншої бази.
Але навіть коли ми зберігаємо документи, вони займають другорядну посаду. Доступ до них повільний. Як тільки ми спираємось на інформацію, недоступну з індексів — наприклад, робимо пошук за скриптом - запит уповільнюється в рази.
Також стикнувся з тим, що навіть просто запит, що повертає велику кількість документів — ненормально витратна операція. Тобто якщо хочете забрати з OpenSearch дамп чи щось схоже, краще обрати невеликий розмір сторінки. Так, запитів зробите більше, зате вони економніше використають памʼять та тому загальний час буде менше.
Тобто шукати ми можемо багато, а читати — менше. Ще одна цікава відмінність від типової бази даних. Та дивись, для деяких сценаріїв це дуже вигідно — наприклад, якщо документів дуже багато, але цікавлять нас одиниці. Як-от типове зберігання журналу. А для інших сценаріїв — взагалі не підходить.
🎙️ The Search Party — Episode 2!
Host Nate Boot, #OpenSearchAmbassador, recaps OpenSearch at KubeCon CloudNativeCon 2025, Knowledge Management World, and AWS re:Invent, plus highlights from the OpenSearch 3.4.0 release. 🎥 https://www.youtube.com/watch?v=qz-sPjtLhrU
Featuring conversations with Ryan Peirce, Alex Degitz, and Dotan Horovits, OpenSearch Ambassador.
📊 Analyst take: IBM’s Premier Membership reinforces OpenSearch as a key platform for open agentic AI and RAG. OpenSearch 3.3 adds persistent agentic memory, agentic search, and improved observability, while DataStax scales vector search to billions, proving enterprise-ready infrastructure.
