Pros
- An open-source, distributed NoSQL database designed to handle massive data volumes with linear throughput increases across commodity hardware, ensuring high scalability .
- Delivers global availability with low-latency reads and writes using a multi-master replication model, meaning no single point of failure .
- Highly flexible schema with the Cassandra Query Language (CQL) supports dynamic column addition and user-defined types without downtime .
Cons
- It explicitly does not support cross-partition transactions, distributed joins, or foreign keys, which limits its use for complex relational data models .
- Consistency is eventually consistent by default, which can be a challenge for applications requiring immediate consistency across all nodes .
- The platform has a steep learning curve and requires careful configuration, particularly for replication and partition key design, to achieve optimal performance .
