A Powerful Upgrade Built on Apache Lucene 10
At the heart of OpenSearch 3 is the upgrade to Lucene 10 — a new engine delivering significant performance gains across workloads.
What This Means in Practice
-
Up to 60% lower search latency compared to OpenSearch 2.x
-
Up to 80% performance improvement compared to 1.x
-
Faster, more responsive queries for both keyword and vector search
-
Improved RAM management and cluster stability
In real-world benchmark tests:
-
A standard
_searchquery dropped from 126 ms (v2.19) to 89 ms (v3.3) — a 41.5% improvement. -
Derived source queries improved by 75%, dropping from 564 ms to 142 ms.
The result: noticeably faster dashboards, APIs, and AI-driven search applications.
Smarter Storage & Efficiency
Performance isn’t the only leap forward — version 3 introduces major efficiency enhancements.
Sparse Indexing
The engine intelligently skips irrelevant data blocks during queries, speeding up search operations and reducing unnecessary processing.
Derived Source for Vector Search
For vector workloads, derived source reduces redundant storage — lowering costs while improving speed. In internal testing, derived source queries ran up to 70% faster on version 3 compared to version 2 using identical datasets.
This means more efficient clusters, lower storage overhead, and better ROI for search-heavy applications.
Why Upgrade to Version 3?
Upgrading isn’t just about speed — it’s about future-proofing your search architecture.
With version 3, you get:
-
Immediate performance improvements
-
Enhanced stability under complex workloads
-
Better memory utilization
-
Optimized support for AI and vector search
-
Seamless management through Aiven’s platform
Because Aiven handles the operational complexity, upgrading is streamlined and fully managed.
Upgrade Paths to Version 3.3
Depending on your current version, supported upgrade routes include:
-
1.3 → 2.19 → 3.3
-
2.17 → 2.19 → 3.3
Important:
As with any major version upgrade, review the release notes carefully and assess potential breaking changes. If you’re running version 1.x, you’ll first need to upgrade to 2.19 and may need to re-index your data.
Getting Started
OpenSearch 3.3.2 is available now in the Aiven Console. You can:
-
Launch a new version 3.3 service
-
Upgrade an existing cluster
-
Deploy via Console, API, Terraform, or Kubernetes Operators
Whether you’re building a new analytics platform or modernizing an existing search cluster, version 3 delivers a clear performance advantage.
The Bottom Line
OpenSearch 3 isn’t just an incremental update — it’s a core performance transformation powered by Lucene 10.
With faster query times, smarter storage, and improved efficiency, Aiven for OpenSearch version 3 gives you the tools to build responsive, scalable, AI-ready applications.
Ready to experience the leap? Version 3 is waiting.
