Cassandra is an open source distributed NoSQL database developed by Apache. It provides a highly available, decentralized, and fault-tolerant data store for applications. Cassandra is used for managing large amounts of data across multiple servers and is commonly used for applications requiring real-time access to data.
Cassandra is a NoSQL database that is designed to store and manage large amounts of data across multiple servers. It is built on an architecture that is highly available, decentralized, and fault-tolerant. Cassandra is an open source project developed by Apache and is written in Java.
Cassandra is based on a distributed system of nodes that store data in a ring structure. Each node in the cluster is responsible for a portion of the data and communicates with other nodes to replicate and manage the data. Cassandra is designed to be highly available and can tolerate failures of individual nodes by replicating data across multiple nodes.
Cassandra is optimized for high performance and scalability. It is designed to handle large amounts of data and can scale to thousands of nodes. Cassandra is also designed to be highly fault-tolerant and can tolerate failures of individual nodes without affecting the availability of the entire system.
Cassandra is used for applications that require real-time access to data. It is used by companies such as Netflix, Apple, and eBay for applications such as analytics, streaming media, and content management.
Cassandra was originally developed at Facebook in 2008. It was open sourced in 2009 and became an Apache project in 2010.
In 2011, Cassandra version 1.0 was released. This version introduced the CQL (Cassandra Query Language), which is a SQL-like query language for Cassandra.
In 2012, Cassandra version 2.0 was released. This version introduced support for secondary indexes, materialized views, and user-defined functions.
In 2014, Cassandra version 3.0 was released. This version introduced support for lightweight transactions and triggers.
In 2016, Cassandra version 4.0 was released. This version introduced support for lightweight transactions and triggers.
Cassandra provides a number of features for managing large amounts of data:
Cassandra is used by companies such as Netflix, Apple, and eBay for applications such as analytics, streaming media, and content management. For example, Netflix uses Cassandra to store and manage its streaming media data.
Pros:
Cons:
Cassandra has been criticized for its complex setup and configuration. It is not suitable for applications that require complex transactions or complex queries.
Cassandra is related to other NoSQL databases such as MongoDB, HBase, and Redis.
