Class DataCatalogClient (3.2.1)

DataCatalogClient(*, credentials: Optional[google.auth.credentials.Credentials] = None, transport: Optional[Union[str, google.cloud.datacatalog_v1.services.data_catalog.transports.base.DataCatalogTransport]] = None, client_options: Optional[google.api_core.client_options.ClientOptions] = None, client_info: google.api_core.gapic_v1.client_info.ClientInfo = <google.api_core.gapic_v1.client_info.ClientInfo object>)

Data Catalog API service allows clients to discover, understand, and manage their data.

Properties

transport

Returns the transport used by the client instance.

Returns
Type	Description
`DataCatalogTransport`	The transport used by the client instance.

Methods

DataCatalogClient

DataCatalogClient(*, credentials: Optional[google.auth.credentials.Credentials] = None, transport: Optional[Union[str, google.cloud.datacatalog_v1.services.data_catalog.transports.base.DataCatalogTransport]] = None, client_options: Optional[google.api_core.client_options.ClientOptions] = None, client_info: google.api_core.gapic_v1.client_info.ClientInfo = <google.api_core.gapic_v1.client_info.ClientInfo object>)

Instantiates the data catalog client.

Parameters
Name	Description
`credentials`	`Optional[google.auth.credentials.Credentials]` The authorization credentials to attach to requests. These credentials identify the application to the service; if none are specified, the client will attempt to ascertain the credentials from the environment.
`transport`	`Union[str, DataCatalogTransport]` The transport to use. If set to None, a transport is chosen automatically.
`client_options`	`google.api_core.client_options.ClientOptions` Custom options for the client. It won't take effect if a `transport` instance is provided. (1) The `api_endpoint` property can be used to override the default endpoint provided by the client. GOOGLE_API_USE_MTLS_ENDPOINT environment variable can also be used to override the endpoint: "always" (always use the default mTLS endpoint), "never" (always use the default regular endpoint) and "auto" (auto switch to the default mTLS endpoint if client certificate is present, this is the default value). However, the `api_endpoint` property takes precedence if provided. (2) If GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is "true", then the `client_cert_source` property can be used to provide client certificate for mutual TLS transport. If not provided, the default SSL client certificate will be used if present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not set, no client certificate will be used.
`client_info`	`google.api_core.gapic_v1.client_info.ClientInfo` The client info used to send a user-agent string along with API requests. If `None`, then default info will be used. Generally, you only need to set this if you're developing your own client library.

Exceptions
Type	Description
`google.auth.exceptions.MutualTLSChannelError`	If mutual TLS transport creation failed for any reason.

Returns

Type Description

google.cloud.datacatalog_v1.types.Entry Entry Metadata. A Data Catalog Entry resource represents another resource in Google Cloud Platform (such as a BigQuery dataset or a Pub/Sub topic) or outside of Google Cloud Platform. Clients can use the linked_resource field in the Entry resource to refer to the original resource ID of the source system. An Entry resource contains resource details, such as its schema. An Entry can also be used to attach flexible metadata, such as a Tag.

create_entry_group

create_entry_group(request: Optional[google.cloud.datacatalog_v1.types.datacatalog.CreateEntryGroupRequest] = None, *, parent: Optional[str] = None, entry_group_id: Optional[str] = None, entry_group: Optional[google.cloud.datacatalog_v1.types.datacatalog.EntryGroup] = None, retry: google.api_core.retry.Retry = <_MethodDefault._DEFAULT_VALUE: <object object>>, timeout: Optional[float] = None, metadata: Sequence[Tuple[str, str]] = ())

Creates an EntryGroup.

An entry group contains logically related entries together with Cloud Identity and Access Management policies that specify the users who can create, edit, and view entries within the entry group.

Data Catalog automatically creates an entry group for BigQuery entries ("@bigquery") and Pub/Sub topics ("@pubsub"). Users create their own entry group to contain Cloud Storage fileset entries or custom type entries, and the IAM policies associated with those entries. Entry groups, like entries, can be searched.

A maximum of 10,000 entry groups may be created per organization across all locations.

Users should enable the Data Catalog API in the project identified by the parent parameter (see Data Catalog Resource Project for more information).

Type Description

google.iam.v1.policy_pb2.Policy Defines an Identity and Access Management (IAM) policy. It is used to specify access control policies for Cloud Platform resources. A Policy is a collection of bindings. A binding binds one or more members to a single role. Members can be user accounts, service accounts, Google groups, and domains (such as G Suite). A role is a named list of permissions (defined by IAM or configured by users).

Searches Data Catalog for multiple resources like entries, tags that match a query.

This is a custom method (https://cloud.google.com/apis/design/custom_methods) and does not return the complete resource, only the resource identifier and high level fields. Clients can subsequently call Get methods.

Note that Data Catalog search queries do not guarantee full recall. Query results that match your query may not be returned, even in subsequent result pages. Also note that results returned (and not returned) can vary across repeated search queries.

See Data Catalog Search Syntax <https://cloud.google.com/data-catalog/docs/how-to/search-reference>__ for more information.
