- Scalability handles large datasets efficiently
- High performance for read/write intensive applications
- Suitable for modern applications like IoT, social media, and real-time analytics
Cons
- Lack of standardized query languages compared to SQL
- Potential complexity in data consistency and transaction management
- Less mature ecosystems and tools than traditional databases
