Key Features
Serverless Vector Search
Cosdata Serverless is a fully managed vector database service that eliminates the operational complexity of running vector search at scale. Built with our innovative CHANNI technology, it delivers exceptional performance with the simplicity of serverless computing.
Serverless Architecture
Fully managed, auto-scaling vector database
Infinite Scalability
Scale from zero to billions of vectors without any infrastructure management. Our serverless architecture automatically handles capacity planning and scaling.
Hybrid Search
Our hybrid search capabilities deliver highly contextual results by leveraging both semantic retrieval and advanced lexical search, including full-text indexing and SPLADE-enhanced sparse vectors for improved recall and precision.
Pay-Per-Use Pricing
Only pay for the resources you actually consume. No upfront costs, no minimum fees, and minimal base storage costs with compute that scales to match your usage patterns.
Enterprise-Ready
Built with enterprise-grade security, compliance, and reliability. Includes role-based access control, data encryption, and comprehensive audit logging.
CHANNI: Delivering Speed at Scale
The Vector Search Challenge
Vector search systems today face a critical dilemma: choose between the blazing speed of in-memory solutions like HNSW or the cost-effective scalability of disk-based ANN. This trade-off has forced organizations to either bear excessive infrastructure costs or accept compromised performance.
HNSW (In-Memory)
- Exceptional query performance
- High recall rates
- Requires entire index in RAM
- Costly at scale
Disk-Based ANN
- Excellent scalability
- Cost-effective storage
- Higher query latency
- Complex maintenance
The CHANNI Solution
CHANNI (Clustered Heirarchical Approximate Nested Navigable Index) eliminates the traditional trade-off between speed and scale with a novel multi-level architecture that intelligently manages data between memory and disk, combining the advantages of both in-memory and disk-based approaches.
Enter CHANNI: The Best of Both Worlds
- Near-HNSW query performance while keeping most data on disk
- Up to 90% less RAM required
- Scales to billions of vectors without performance degradation
- Simplified maintenance through intelligent cluster operations
Built with components from our market-leading HNSW implementation that offers up to 1,770+ QPS on a single node.
