What is Cassandra

Cassandra is a distributed NoSQL data storage system

Features of Cassandra

Cassandra relies on column family storage, supports a single-table-multi-row data model, and does not support transactions or strong consistency.

Advantages of Cassandra

• High Availability: Cassandra can be distributed across multiple machines, improving system availability.
• High Performance: Cassandra relies on column family storage, which can provide faster write speeds.
• Data Distribution: Cassandra can handle large datasets and distribute data across multiple servers.

Disadvantages of Cassandra

• No Transaction Support: Cassandra's single-table model and write pressure lead to data inconsistency within a single table.
• No Strong Consistency: Cassandra does not guarantee strong consistency, which may result in inconsistent data.

Application Scenarios of Cassandra

• Large Data Storage: Cassandra is an ideal choice for handling large datasets and providing high-availability systems.
• Real-time Data Processing: Cassandra's high-performance features make it suitable for real-time data processing and analysis.
