Apache Cassandra VS PostgreSQL
PostgreSQL is a relational database known for its ACID compliance and strong SQL capabilities, making it ideal for applications requiring complex transactions. In contrast, Apache Cassandra is a NoSQL database designed for high availability and scalability, excelling in handling large volumes of write operations across distributed systems.
Apache Cassandra
Pros:
- High availability and scalability
- Flexible schema design
- Fast write operations
- Designed for distributed data
- Multi-data center replication
Cons:
- Eventual consistency can lead to stale reads
- Limited support for complex queries
- Steeper learning curve for new users
PostgreSQL
Pros:
- ACID compliance
- Rich SQL support
- Strong community support
- Extensive indexing options
- Built-in replication and failover
Cons:
- Performance can degrade with very large datasets
- Not as scalable as NoSQL solutions
- Complex configuration for replication
