Decentralized structured Storage System--cassandra

Cassandra is a distributed storage system that can be used to manage huge amounts of structured data distributed across a large number of inexpensive services, while providing high availability services with no single point of failure. Cassandra is designed to run on an infrastructure consisting of hundreds of nodes, which may be distributed across a number of different data centers, and when the nodes reach this size, a large and small component failure can occur frequently. Cassandra is faced with these failures in managing persistent state, which also drives the reliability and scalability of the software system depending on the Cassandra service, although most cases Cassandra look like a database system and share a lot of design and implementation tools with the database system, But Cassandra does not support a complete relational data model, instead it provides a simple data model client that supports dynamic control of data layouts and data formats, and we designed Cassandra to run on inexpensive hardware, and can achieve high write throughput without sacrificing read efficiency.
