5.8 Big Data and NoSQL
In the previous chapter, we have gone through the key
concepts of ‘Big Data’, i.e., MapReduce. It provides a
parallel computing system to run tasks over distributed
sets of data and then integrate them to a single com-
bined output.
In this chapter, we shall look into another important
concept of Big Data called ‘NoSQL’. The most conven-
tionally used relational databases contains numerous
limitations which pose an extensive difficulty in build-
ing modern enterprise applications. The biggest restric-
tion lies in the rigid schema-based definition of the
database. To break this jinx, comes the concept of ‘Not
Relational SQL’ or ‘NoSQL’. In this chapter, we shall
study the different characteristics of NoSQL databases,
taking the case of one specific NoSQL database called
Cassandra. At the end of this chapter, we shall be able
to gain enough knowledge about NoSQL databases as a
whole and Cassandra in specific.
