The Take First Data Processor selects a specified fraction of rows from a dataset starting at the first row.
The processor works with any dataset.
The subset of the given dataset will be available at the output port for further processing.
In this example we save the first 20 rows of a big dataset to a Result Table.
The input is a dataset called 'books'. It has about 14 000 rows and 10 columns. It is loaded using a Data Table Load Processor.
In this workflow we load the dataset with Data Table Load, then save the original data and the extracted 20 columns to different Result Tables.
We set "Number of Rows" to 20 in the processor configuration.
As result we now have the first 20 rows of the "books" dataset.
