As an application developer, you have almost certainly worked with databases extensively. You must have built products using relational databases like MySQL and PostgreSQL, and perhaps experimented with a document store like MongoDB or a key-value database like Redis. While each of these tools has its strengths, you will now consider whether a distributed database like Cassandra might be the best choice for the task at hand. In this article by Mat Brown , author of the book Learning Apache Cassandra , we'll talk about the major reasons to choose Cassandra from among the many database options available to you. Having established that Cassandra is a great choice, we'll go through the nuts and bolts of getting a local Cassandra installation up and running. By the end of this article, you'll know: When and why Cassandra is a good choice for your application How to install Cassandra on your development machine How to interact with Cassandra using cqlsh How to create a keyspace
