Setting up and configuring Cassandra
Before moving towards setting up and configuring Cassandra, let's explain what Cassandra is and why it is so popular. Cassandra is a NoSQL columnar database. If you need high scalability with high availability then Cassandra is the best choice. It has high read and write performance but with eventual consistency.
Eventual consistency is when you insert a row in a database and at same time another user reads the same table, making it possible that the newly added row would be visible to the user or not. Keyspace in Cassandra is the same as a database in RDMS. The rest of the terminology is the same as RDMS. Cassandra is an open source tool but if you need to manage clusters with designed a UI, then go for DataStax. DataStax provides paid premium services and includes full-time support. Now, let's see how to set up Cassandra.
