What is the "Logic" dropdown option on Data Source Configuration used for?
Question
On the creation screen of a Data Source, there is a drop-down box where you can select a "PriceAnalyzer" logic type. What is it?
Answer
This is a transformation logic - similar to the one in Data Load Flush operation. It is a logic used to transform data already in the Data Source.
You can make elements in the logic with Context "Init" and in this case, loop through results of api.getDatamartRowSet("target")
. Using this strategy, you can update rows with target.addRow(rowMap)
.
Alternatively you can make elements with the context "Row", and access the individual row info using api.getUserEntry("ColumnName")
, and output the result back to the column by "return"ing my transformed result from an element with the name of the column I wish to transform.
It is triggered when data is loaded in a Data Source, either through a file upload, or a flush from a Data Feed.
