The Indexing Processor creates an additional column with an index, starting with a defined value. The default is 0.
This processor operates on any input Dataset, and its configuration is done as follows:
If the new column name (first field) is left empty, then the generated column will have the name "index"
The processor returns the input Dataset with the additional index column as first column.
In this example the Indexing processor will be used to index a Dataset generated by a Custom Input Table:
First the starting index was zero, and then it is changed to four
The new column is the first column from left hand side
