+This sample application show how to use POJOEnricher to enrich streaming data 
using
+external source.
+The operators in order as as follows:
+1. Random data generator which emits data in JSON string format
+2. JSON Parser which takes JSON string and emits POJO
+3. POJO Enricher which enriches input using file and emits output POJO
+4. Line Output Operator which emits line by line output to File System
+The output files start out with a `.tmp` extension and get renamed when they 
reach the
+size bound.
+
+Similar to FSLoader JDBCLoader can be used when JDBC backend is required.
