+POJO Enricher
+=============
+
+## Operator Objective
+This operator receives an POJO ([Plain Old Java
Object](https://en.wikipedia.org/wiki/Plain_Old_Java_Object)) as an incoming
tuple and uses an external source to enrich the data in
+the incoming tuple and finally emits the enriched data as a new enriched
POJO.
+
+POJOEnricher supports enrichment from following external sources:
+
+1. **JSON File Based** - Reads the file in memory having content stored in
JSON format and use that to enrich the data. This can be done using FSLoader
implementation.
+2. **JDBC Based** - Any JDBC store can act as an external entity to which
enricher can request data for enriching incoming tuples. This can be done using
JDBCLoader implementation.
+
+POJO Enricher does not hold any state and is **idempotent**,
**fault-tolerance** and **statically/dynamically partitionable**.
