What are the characteristics of the Cassandra system?
Some features of the Cassandra system are:
- Distributed Architecture: Cassandra utilizes a distributed architecture, allowing data to be stored across multiple nodes, enhancing the scalability and fault tolerance of the system.
- High availability: Cassandra uses a multi-replica mechanism to replicate data between different nodes in the system, providing automatic failover and recovery functions to ensure high system availability.
- High Performance: Cassandra utilizes a strategy of distributed data storage and querying, enabling it to support high levels of concurrent read and write operations while also delivering low-latency query performance.
- Elastic scalability: Cassandra can easily scale out horizontally, allowing users to add nodes as needed to increase the system’s storage capacity and throughput.
- Flexible data model: Cassandra supports table structures similar to relational databases, while also allowing for unstructured and semi-structured data models, meeting various types of data storage requirements.
- High degree of configurability: Cassandra offers a variety of configuration options that can be flexibly adjusted and optimized according to different application scenarios and needs.
- Easy to manage: Cassandra offers a set of management tools for easy cluster management, monitoring, and fault diagnosis.
- Cross-datacenter replication: Cassandra allows for data replication across different data centers, enabling multi-region data backup and disaster recovery.
- There are no single points of failure: Cassandra does not have single points of failure, each node can operate independently and the system will not become unavailable due to the failure of a single node.
- Easy integration: Cassandra offers client drivers and APIs in various programming languages, making it convenient to integrate and interact with other applications.
