At Open Source Summit North America, @theCUBE host Paul Nashawaty caught up with Mukul Karnik from OpenSearch to discuss key highlights from OpenSearch 3.0 and new features in 3.1. Check out their chat covering all things hybrid search, MCP, vector search, observability use cases and agentic AI.

🚀 OpenSearch made a strong showing at #WeAreDevelopers in Berlin.

Jochen Kressin, Director at @eliatra shared how they're using OpenSearch as a vector database, and how 3.0 features like GPU support are driving real impact.

Huge thanks to the OpenSearch community. The momentum is real and the future is bright.

Last month I got to speak at #devoxx Poland for the first time.
It was an amazing experience, speaking on this theater-like huge stage (that's me trying to look up at the folks sitting at the top gallery).
now my #OpenSearch talk is up on YouTube!

Semantic search, meet speed.

Neural sparse models are now in the Sentence Transformers (SBERT) library, thanks to OpenSearch and @huggingface 🎉 Encode sentences into sparse vectors with the same framework and search them fast with OpenSearch. No dense overhead. No latency.

The heart of open source? Community. 💙

At OpenSearchCon, developers, maintainers, and builders come together to share ideas, real-world solutions, and the future of open source search.

🎤 This teaser looks back at the voices who’ve led the way.

See you on September 8-10 at #OpenSearchCon NA!

Hello from WeAreDevelopers in Berlin! Come by @OpenSearchProject Foundation Members @eliatra Booth 206 to talk to us about the #OpenSearch Community! #wearedevelopers

Anyone understand #OpenSearch?

Trying to do the final step of the update which is to update the index and I get this error.

Validation Failed: 1: this action would add [1] total shards, but this cluster currently has [1000]/[1000] maximum shards open

OpenSearch is running on the same server as the mastodon software, so no AWS shenanigans, and I've not done anything to customise it for our server.

What really happens during a bulk index in OpenSearch?
In part 6 of this deep dive, Uber’s Michael Froh breaks down REST index flows, bulk processing, shard coordination, and Lucene writes. A must-watch for builders, debuggers, and the curious alike.

Bis bald!

Catch @horovits at AI_dev Open Source GenAI & ML Summit as he breaks down how OpenSearch has evolved into a powerful vector database, combining traditional lexical and vector-based similarity search, in one complete package.

📢 Thrilled to share that, through a collaborative effort between the @OpenSearchProject and @huggingface neural sparse models are now available in the Sentence Transformers library. 🤗

The Sentence Transformers (a.k.a. SBERT) library, developed by @UKPLab and maintained by #HuggingFace, is a Python framework designed to generate semantically meaningful embeddings for sentences, paragraphs, and images.

Congrats to all involved! 👏

Querying nested JSON has been a pain in the neck. Often you find yourself needing to extract specific values from deeply nested JSON objects, or transform nested arrays into a more analyzable format, and find yourself using complex workarounds with poor query performance.

The latest #OpenSearch 3.1 release features new PPL query commands exactly for that:

Логирование в конвейере дебетовых карт: как мы сделали его удобным для себя

Статья о том, как мы улучшали логи внедрением сквозных идентификаторов и не только. Делали это для того, чтобы упростить и ускорить разбор возникающих ошибок. Это в разы сократило время разбора. Статья может быть полезна backend-разработчикам, лидам, тестировщикам, аналитикам, которые проектируют и разрабатывают сложные системы. Код написан на java и соседних технологиях, но подходы, я уверен, универсальны. Они упростят жизнь при разборе ошибок на проде и на тестовых стендах.
