+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**.
+
+## Operator Usecase
+1. Bank ***transaction records*** usually contains customerId. For further
analysis of transaction one wants the customer name and other customer related
information.
+Such information is present in another database. One could enrich the
transaction's record with customer information using POJOEnricher.
+2. ***Call Data Record (CDR)*** contains only mobile/telephone numbers of
the customer. Customer information is missing in CDR. POJO Enricher can be used
to enricher
