Distributed Databases
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Distributed databases are systems where data is stored across multiple physical locations, often spanning multiple servers or data centers. They enable data sharing and management across geographically dispersed sites, offering scalability, fault tolerance, and improved performance for large-scale applications.
Key Features
- Data distribution across multiple nodes or locations
- Support for horizontal scalability
- Fault tolerance and high availability
- Data replication for redundancy
- Distributed query processing and transaction management
- Consistency models ranging from strong to eventual consistency
- Network communication overhead management
Pros
- Enhanced scalability to handle growing data volumes
- Improved system resilience and fault tolerance
- Reduced latency by localizing data access
- Flexibility in managing geographically distributed data
Cons
- Increased complexity in system design and maintenance
- Challenges in ensuring data consistency across nodes
- Higher network overhead due to data synchronization
- Potential difficulties in query optimization across distributed datasets
