Glossary of Expectations

This is a list of all built-in Expectations. Expectations are extendable so you can create custom expectations for your data domain! To do so see this article: Building Custom Expectations.

Dataset

Dataset objects model tabular data and include expectations with row and column semantics. Many Dataset expectations are implemented using column_map_expectation and column_aggregate_expectation decorators.

Not all expectations are currently implemented for each backend. Please see Table of Expectation Implementations By Backend.
