Dataset audit

This plugin provides a recipe that takes a SQL-based or HDFS-based dataset as input, and outputs an audit of the data in the input dataset.

The output is a dataset with one line per column in the input dataset. For each column, the recipe outputs:

  • Type
  • Cardinality (number of distinct values)
  • Number of missing/empty values
  • Most frequent value and most frequent value count
  • For numerical columns: min, max, avg

The recipe uses in-processing or in-Hadoop processing, as appropriate for the input dataset

A sample output.
