The ingress and egress patterns for the NoSQL data
This section describes the patterns that deal with ingesting data from two classes of NoSQL data. To illustrate the power of Pig to readily support NoSQL databases and the use cases associated with it, we have chosen document databases such as MongoDB and columnar databases such as HBase.
