Specify a New Data Indicator for a Data Source
To configure incremental processing in a data flow, you select the data column to use as the flow new data indicator in the data source. This indicator determines when new data is detected since the last time the data flow was executed. For example, you might select a timestamp column.
Before you start, create a connection to one of the supported databases,
for example Oracle, Oracle Autonomous Data Warehouse, Apache Hive, Hortonworks Hive, or Map R Hive.
