OpenSearch has become a cornerstone of open source search and observability, empowering developers and organizations to derive meaningful insights from unstructured data at scale.
The past year marks a significant milestone in its journey, with OpenSearch officially joining The Linux Foundation, further cementing its position in the open source ecosystem.
Now, after two years of 2.x, the next major release is here, and it brings significant advancements in performance, data management, vector database functionality, and much more. In this episode we dive into the 3.0 release, across lexical, semantic, and hybrid search, vector database improvements, observability capabilities, performance boosts, and much more. We also look at the community and ecosystem, the recent move of the project under The Linux Foundation, and some of the interesting use cases out there.
Our guests for this episode are Carl Meadows, Chair of the Governing Board of the OpenSearch Software Foundation, and Pallavi Priyadarshini, member of the Technical Steering Committee and the OpenSearch 3.0 release manager.
