Cassandra: Introduction
Let’s explore Cassandra and its use cases.
Goal
Design a distributed and scalable system that can store a huge amount of structured data, which is indexed by a row key where each row can have an unbounded number of columns.
Background
Cassandra is an open-source Apache project. It was originally developed at Facebook in 2007 for their inbox search feature. The Apache Cassandra architecture is designed to provide scalability, availability, and reliability to store large amounts of data
