Cassandra is a cluster-computing, scalable, distributed database system built for availability and tolerance. It offers a special method of organizing data around queries which we'll explore in this article. This method, called "query-first," focuses on how to search for information first, and then set up the database based on those searches or queries. It's different from how you'd organize in a traditional database design. This helps to make Cassandra faster and more efficient.
In this article, this approach will be explained and some examples will show you how to use it.
