The above example shows how to move data from one database into another. It defines a connection to a local Postgres (left) and a remote DB2 production database (right). The flow moves local orders stored in Postgres to the DB2 production database. Which orders to move is specified through messages coming in from a queue called MoveOrderRequests. Each request initiates a query on the local Postgres database which returns a set of orders. Each of them is inserted into the DB2 database and therafter deleted in the local Postgres database.
