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.
