The Dac-Man API

The top-level dacman module provides methods and classes for doing data comparisons at scale. Data can be compared using dacman.diff().

dacman.diff()

def dacman.diff(new_file, old_file, *argv, comparator_plugin=None)

Function to perform a single comparison using the specified plug-in.

dacman.DataDiffer

class dacman.DataDiffer(comparisons, executor=Executor.DEFAULT)

Class that compares multiple files or objects. This class takes a list of comparisons and performs the comparisons in parallel. The executor argument specifies the type of runtime to be used for doing the comparisons.

use_plugin(plugin)

Method to set a specific plug-in for comparing the files. If no plug-in is set, then Dac-Man will select one of the internal plug-ins based on file/data types.
