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
