- High Availability: Even if one replica fails, others will remain accessible, maintaining index availability.
- Reduced Latency: Replicas can be placed in different regions, bringing the index closer to clients and reducing latency for geographically distributed users.
- Performance Optimization: You can create more performant indexing by dividing large indexes into smaller, more manageable namespaces.
- Multi-Tenant Data Isolation: Namespaces provide a mechanism to isolate data belonging to different tenants or applications within a single index.
