The great_expectations utility helps data teams eliminate pipeline debt, through data testing, documentation, and profiling. Note that this utility is pinned to an older version since the Great Expectations CLI is now deprecated.
Getting Started
Prerequisites
If you haven't already, follow the initial steps of the Getting Started guide:

Add additional database drivers
If you are using Great Expectations to validate data in a database or warehouse, you
might need to install the appropriate drivers. Common options are supported by Great Expectations
as pip extras, and any additional packages you may want can be added too by configuring
a custom pip_url
for the great_expectations
utility:
Find the
great_expectations
plugin definition in yourmeltano.yml
project fileUpdate the
pip_url
property to include the desired additional extras and packages:utilities: - name: great_expectations variant: great-expectations pip_url: great_expectations[redshift] awscli
Re-install the plugin:
meltano install utility great_expectations
The next time you run Great Expectations, you will be able to connect to a new type of database, like Redshift in the example.
