A Trio of Power: Optimized Vector Indexing for Every Need

Developing AI applications and agentic systems presents unique challenges, particularly in managing the complex, high-dimensional vector data that these systems generate. A recent Couchbase FY 2026 CIO AI Survey revealed that a significant 28% of CIOs cited difficulties in managing or accessing necessary data as a major disruptor to AI projects. Furthermore, a mere 16% reported having a vector database capable of efficiently storing, managing, and indexing high-dimensional vector data.

Couchbase 8.0 directly addresses these pain points with its innovative, three-pronged indexing approach. This comprehensive solution is designed to support a wide spectrum of vector retrieval scenarios, from applications needing broad contextual understanding to those requiring granular control over prompt variables.

The Three Pillars of Vector Indexing in Couchbase 8.0:

Hyperscale Vector Index (HVI): This is Couchbase’s flagship offering, engineered to scale beyond a billion vector index records without sacrificing responsiveness or performance. Built on the robust DiskANN nearest-neighbor search algorithm, utilizing the Vamana directed graph construction algorithm, HVI offers exceptional flexibility. It can operate across partitioned disks for distributed processing and scaling, or run in-memory for datasets where speed is paramount. This index is ideal for applications that require massive vector capacity and lightning-fast retrieval.
Composite Vector Index: This index type is a powerful ally for scenarios where pre-filtered queries are essential to scope the specific vectors being sought. Composite vector indexes can be stored and partitioned just like other global secondary indexes in Couchbase, ensuring efficient vector retrieval for targeted use cases. This is particularly useful when you need to combine vector search with other metadata filters for precise results.
Search Vector Index: For truly sophisticated search requirements, the Search Vector Index enables queries directly through Couchbase’s search service. This supports hybrid searches that seamlessly combine vectors with lexical search and structured query criteria within a single SQL++ request. Developers can now achieve unprecedented performance, accuracy, and cost savings by selecting the vector index that best suits their specific application needs – whether it’s optimizing for query complexity, sheer volume of vectors, or absolute precision.

This rare level of optionality empowers organizations to deploy context-defining vectors that are precisely optimized for their unique application requirements, leading to more effective and efficient AI solutions.

Fortifying AI with Unwavering Security and Compliance

As AI applications become increasingly mission-critical, so too does the need for robust security and stringent compliance. Recent data from Couchbase indicates that over a third of CIOs express lack of confidence in meeting security or compliance demands, posing a significant hurdle for AI project implementation.

Couchbase 8.0 proactively tackles these concerns with a suite of enterprise-grade security and compliance features:

Native Data at Rest Encryption (DARE): This out-of-the-box feature provides essential built-in security. Data stored on disk is automatically encrypted, and then transparently decrypted when accessed, safeguarding sensitive information from unauthorized eyes.
Key Management Interoperability Protocol (KMIP) Support: Seamless, cross-platform management of encryption keys is now simplified through KMIP support, further bolstering data security and streamlining operations.
Enhanced Cross Data Center Replication (XDCR): Bidirectional active-active conflict awareness detection now extends to mobile buckets. This capability allows mobile clients to sync with the closest cluster, dramatically improving reliability, scalability, and performance. It acts as a crucial safeguard against data center failures, ensuring that sensitive data is stored locally while non-sensitive data is replicated across regions. This is invaluable for globally distributed businesses needing to comply with regional data regulations while supporting a mobile-first user base.
Intelligent Auto-Failover: New intelligent auto-failover capabilities ensure continuous operations even during unforeseen system disruptions, such as reaching disk capacity or the disappearance of transient buckets.
