What are the main benefits of using Cosmos DB over traditional databases?
| Feature | Cosmos DB | Traditional Relational Databases (SQL-based) |
| Scalability | Horizontal scaling with partitioning | Vertical scaling (hardware-dependent) |
| Availability | Multi-region, high-availability | Typically single-region with failover |
| Latency | Low-latency, real-time responses | Can be slow for global applications |
| Indexing | Automatic indexing of all fields | Requires manual indexing strategies |
| Multi-model support | Supports document, key-value, graph, column-family models | Primarily relational model |
Cosmos DB is ideal for applications requiring high-speed, real-time data access across multiple regions.
