This pattern entails getting NoSQL alternatives in place of traditional RDBMS to facilitate the rapid access and querying of big data. The NoSQL database stores data in a columnar, non-relational style. It can store data on local disks as well as in HDFS, as it is HDFS aware. Thus, data can be distributed across data nodes and fetched very quickly.
Let's look at four types of NoSQL databases in brief:
