PostgreSQL VS CouchBase
PostgreSQL is a powerful relational database known for its advanced SQL capabilities and ACID compliance, making it ideal for transactional applications. In contrast, CouchBase is a NoSQL database that excels in flexibility and scalability, making it suitable for high-performance applications with rapidly changing data requirements.
PostgreSQL
Pros:
- ACID compliance ensures reliable transactions
- Rich query capabilities with SQL support
- Extensible with custom functions and types
- Strong community support and extensive documentation
- Supports JSON data types for semi-structured data
Cons:
- Can be complex to set up and manage
- Performance can degrade with large datasets if not optimized
- Limited horizontal scaling compared to NoSQL solutions
CouchBase
Pros:
- Flexible schema allows for easy adjustment
- High scalability and performance for large datasets
- Built-in caching for fast read operations
- Multi-model capabilities (document, key-value)
- Cross datacenter replication for high availability
Cons:
- Eventual consistency model may not suit all applications
- Limited support for complex querying compared to SQL
- Higher resource consumption for certain workloads
