Extension of InferredAssetFilePathDataConnector used to connect to S3

The InferredAssetS3DataConnector is one of two classes (ConfiguredAssetS3DataConnector being the other one) designed for connecting to filesystem-like data, more specifically files on S3. It connects to assets inferred from bucket, prefix, and file name by default_regex.

InferredAssetS3DataConnector that operates on S3 buckets and determines the data_asset_name implicitly (e.g., through the combination of the regular expressions pattern and group names)

build_batch_spec(self, batch_definition: BatchDefinition)

Build BatchSpec from batch_definition by calling DataConnector’s build_batch_spec function.


batch_definition (BatchDefinition) – to be used to build batch_spec


BatchSpec built from batch_definition

_get_data_reference_list(self, data_asset_name: Optional[str] = None)

List objects in the underlying data store to create a list of data_references.

This method is used to refresh the cache.

_get_full_file_path(self, path: str, data_asset_name: Optional[str] = None)
great_expectations.datasource.data_connector.inferred_asset_s3_data_connector._check_valid_s3_path(path: str) → None

Performs a basic check for validity of the S3 path
