transformations:metadata

Table metadata

This action 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 actions it allows dealing with datasets which column names are not fixed or not known in advance.

It can also be used to obtain the total number of rows, or a list of column names in a table.
