Table metadata
This transformation obtains various metadata of the current dataset, namely:
- Total number of columns
- Total number of rows
- Column names
Use cases
Obtaining column names can be helpful in many cases. Together with Rename with lookup and Select columns by lookup transformations it allows dealing with datasets which column names are not fixed or not known in advance.
