TableMetricProvider
- class great_expectations.expectations.metrics.table_metric_provider.TableMetricProvider#
-
Base class for all Table Metrics, which define metrics to be calculated across a complete table.
An example of this is table.column.unique, which verifies that a table contains unique, non-duplicate columns.
- Parameters:
-
-
metric_name (str) – A name identifying the metric. Metric Name must be globally unique in a great_expectations installation.
-
domain_keys (tuple) – A tuple of the keys used to determine the domain of the metric.
-
value_keys (tuple) – A tuple of the keys used to determine the value of the metric.
-
In some cases, subclasses of MetricProvider, such as TableMetricProvider, will already have correct values that may simply be inherited by Metric classes.
