High-performance vector architectures

Design vector retrieval to work at scale.

Consider:

• sharding
• indexing
• replicas
• partitioning
• multi-index architecture
• domain-specific indexes
• hierarchical indexing

OpenSearch can be used for:

• vector search
• filtering
• hybrid search
• scaling retrieval workloads

Knowledge Base
├── HR index
├── Finance index
├── Legal index
└── Engineering index

This can help isolate domains and apply domain-specific policies.

Do not introduce complex sharding/indexing unless scale or workload requirements justify it.
