Built for the AI era
Couchbase 8.0 unifies on-premises and cloud data management with massive vector scalability, built-in AI query intelligence, and new enterprise-grade operational controls. It’s the only data platform supporting transactional, analytical, and AI workloads together optimized for both developers and DevOps.
Precision retrieval
Composite vector index for search applications where prefiltering massive data is needed.
Hybrid queries
Search vector index combines multiple methods – lexical (keyword) with semantic (vector) for context-rich retrieval.
Unified platform
Operate across on premises, DBaaS, Kubernetes, and embedded in mobile apps.
Vector Search, Operations, and Security – all upgraded
Couchbase 8.0 introduces major advances for developing and managing AI and other critical applications at scale. From billion-scale vector indexing to new failover logic and encryption at rest, every service is faster, smarter, and easier to manage.

Common questions about Couchbase 8.0
Get quick answers to the most common topics regarding our latest server version.
What makes hyperscale vector index unique?
It supports billions of vectors with millisecond retrieval speeds using a DiskANN-based design.
How does Couchbase handle AI data securely?
Encryption at rest, KMIP key management, and event monitoring ensure data integrity and compliance.
Can I mix vector and text search?
Yes. Use the search vector index for hybrid vector + lexical queries.
How does 8.0 improve uptime?
Automatic failover, rebalancing, and faster startup ensure continuous operations.
Where can I see a list of Changes by Couchbase Service?
By reviewing the Couchbase 8.0 announcement blog.
What’s the difference between Hyperscale and Composite Vector Indexes?
Hyperscale helps RAG-style use cases when you cannot anticipate what a prompt is going to ask an LLM, while Composite vector indexes use prefiltering parameters to narrow the vectors to include in a prompt. Both offer millisecond response so RAG workflows do not slow down.
