If faster vector search, reduced storage requirements, and more powerful observability are on your list, OpenSearch 3.9 is worth a look.
Key updates include:
• Neural sparse ANN search with 39% higher throughput, 3.3x faster index builds, and an 8x smaller JVM heap in testing
• Native half_float vectors that can reduce vector memory and storage by roughly 50%
• New 2-bit and 4-bit scalar quantization options for tuning compression vs. recall
• A unified view for alerts, anomalies, and forecasts
• Adaptive per-action concurrency limits for protecting clusters under load
• Index-level search pruning that reduced tail latency by more than 80% and can_match requests by nearly 98% in local benchmarks

At KubeCon + CloudNativeCon NA, OpenSearch Ambassador Brian Graf shared how to index Kubernetes objects in OpenSearch to make cluster data searchable and easier to explore.
A few moments from his Tip Talk, Your Cluster Is a Dataset, at the Starlight Summit Zone.

Great open source maintainers do more than write great code.
OpenSearch maintainers share what the role really takes, their journeys into maintainership, and how to grow the next generation of open source leaders.

If you're at Observability Day today in Salt Lake City, catch a live demo of agent observability with OpenSearch and OpenTelemetry's GenAI semantic conventions.
See how developers can trace agent behavior, investigate failures, and gain better visibility into complex AI workflows.
You don't need to know every line of code to become an OpenSearch maintainer.
For Srikanth Padakanti, it started with fixing a flaky test. Three and a half years later, he's an OpenSearch Data Prepper maintainer, contributing to everything from ingestion and observability to an RFC for indexing data directly from object storage without Kafka in the middle.
Srikanth shares how community feedback, code reviews, and a willingness to keep contributing shaped his journey from first-time contributor to maintainer.

OpenSearch is becoming far more than a search engine.
As the retrieval layer for enterprise AI, OpenSearch helps find the right information, enforce access permissions, and provide relevant context before an AI model responds or an agent takes action.

OpenSearch production adoption has nearly doubled. AI is a big reason why.
In a conversation with @TFiR_io, OpenSearch Software Foundation Executive Director Bianca Lewis discusses what's driving adoption, why enterprises are rethinking fragmented data infrastructure, and where OpenSearch fits.

An AI agent finding the right document isn't the same as an AI agent making the right decision. @IBM's Pushkala Pattabhiraman uses a simple customer return scenario to unpack retrieval, memory, and evidence in agentic systems.

Traffic spikes are a brutal test of search infrastructure. At OpenSearchCon North America 2026, member company @Uber's Mingmin Chen shared how OpenSearch supports rides, maps, and Uber Eats, and what it takes to keep search resilient at scale. The deeper engineering story is in load shedding and improvements contributed back to the ecosystem.

How do you make search work for one of the world's most demanding scientific environments?
Member company @CERN's Sokratis Papadopoulos takes us through ten years of search infrastructure, from the Large Hadron Collider to security and monitoring workloads. There's also a look at using an OpenSearch MCP server to interact with monitoring data.

From vector search to observability, OpenSearch is doing a lot more than traditional search.
At OpenSearchCon NA, we caught up with Dmitry Kan and Tony Piazza from Aiven to discuss OpenSearch's expanding use cases, capabilities, and ability to support workloads at scale.
Thanks to Aiven for sponsoring the event, delivering a keynote, and supporting the OpenSearch community.

89% know OpenSearch. But how many know what it can actually do?
According to the 2026 Open Data Infrastructure Report, 62% of OpenSearch users already run AI workloads, yet only 36% consider their deployments mission-critical.
At Open Source Summit Europe, OpenSearch Executive Director Bianca Lewis discussed what’s driving adoption, why awareness of its full capabilities still lags, and what it takes to move from experimentation to production.

How do you ingest over 3TB of data daily while reporting zero Severity 1 escalations since 2024?
@Akamai migrated to OpenSearch to reduce licensing costs and gain greater control over its analytics infrastructure.
With proactive monitoring through NeverBlink AI and expert support from OpenSearch Software Foundation member @BigDataBoutique, its seven-person SRE team can identify issues early and resolve potential bottlenecks in minutes rather than hours.
