delete_batch_definition(name: str)→ None#

Delete a batch definition.

Parameters

name (str) – Name of the BatchDefinition to delete.

get_batch_definition(name: str)→ great_expectations.core.batch_definition.BatchDefinition#

Get a batch definition.

Parameters

name (str) – Name of the BatchDefinition to get.

Raises

KeyError – If the BatchDefinition does not exist.

Validates that the batch definition column is of a permissible type

This isn’t meant to be called directly. This is called internally when a batch definition

is added. Data asset implementers can override this for their specific data asset.

Raises

SqlAddBatchDefinitionError – The specified column to partition on is not of a permissible type for batching (ie date or datetime) or no data is present in this column.
