Class DataCatalogClient (3.4.3)

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 you to discover, understand, and manage your 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.

You can create entries only with 'FILESET', 'CLUSTER', 'DATA_STREAM', or custom types. Data Catalog automatically creates entries with other types during metadata ingestion from integrated systems.

You must enable the Data Catalog API in the project identified by the parent parameter. For more information, see Data Catalog resource project <https://cloud.google.com/data-catalog/docs/concepts/resource-project>__.

An entry group can have a maximum of 100,000 entries.

Parameters
Name	Description
`request`	`Union[google.cloud.datacatalog_v1.types.CreateEntryRequest, dict]` The request object. Request message for CreateEntry.
`parent`	`str` Required. The name of the entry group this entry belongs to. Note: The entry itself and its child resources might not be stored in the location specified in its name. This corresponds to the `parent` field on the `request` instance; if `request` is provided, this should not be set.
`entry_id`	`str` Required. The ID of the entry to create. The ID must contain only letters (a-z, A-Z), numbers (0-9), and underscores (_). The maximum size is 64 bytes when encoded in UTF-8. This corresponds to the `entry_id` field on the `request` instance; if `request` is provided, this should not be set.
`entry`	`google.cloud.datacatalog_v1.types.Entry` Required. The entry to create. This corresponds to the `entry` field on the `request` instance; if `request` is provided, this should not be set.

Returns

Type Description

google.cloud.datacatalog_v1.types.Entry Entry metadata. A Data Catalog entry represents another resource in Google Cloud Platform (such as a BigQuery dataset or a Pub/Sub topic) or outside of it. You 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, for example, its schema. Additionally, you can attach flexible metadata to an entry in the form of a Tag.

create_entry_group

create_entry_group(request: Optional[Union[google.cloud.datacatalog_v1.types.datacatalog.CreateEntryGroupRequest, dict]] = 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 entry group.

An entry group contains logically related entries together with Cloud Identity and Access Management </data-catalog/docs/concepts/iam>__ policies. These policies specify users who can create, edit, and view entries within entry groups.

Data Catalog automatically creates entry groups with names that start with the @ symbol for the following resources:

BigQuery entries (@bigquery)
Pub/Sub topics (@pubsub)
Dataproc Metastore services (@dataproc_metastore_{SERVICE_NAME_HASH})

You can create your own entry groups for Cloud Storage fileset entries and custom entries together with the corresponding IAM policies. User-created entry groups can't contain the @ symbol, it is reserved for automatically created groups.

Entry groups, like entries, can be searched.

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

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). A binding can optionally specify a condition, which is a logic expression that further constrains the role binding based on attributes about the request and/or target resource. **JSON Example** { "bindings": [ { "role": "roles/resourcemanager.organizationAdmin", "members": [ "user:mike@example.com", "group:admins@example.com", "domain:google.com", "serviceAccount:my-project-id@appspot.gserviceaccount.com" ] }, { "role": "roles/resourcemanager.organizationViewer", "members": ["user:eve@example.com"], "condition": { "title": "expirable access", "description": "Does not grant access after Sep 2020", "expression": "request.time < timestamp('2020-10-01t00:00:00.000z')",="" }="" }="" ]="" }="" **yaml="" example**="" bindings:="" -="" members:="" -="" user:\="" mike@example.com="" -="" group:\="" admins@example.com="" -="" domain:google.com="" -="" serviceaccount:\="" my-project-id@appspot.gserviceaccount.com="" role:="" roles/resourcemanager.organizationadmin="" -="" members:="" -="" user:\="" eve@example.com="" role:="" roles/resourcemanager.organizationviewer="" condition:="" title:="" expirable="" access="" description:="" does="" not="" grant="" access="" after="" sep="" 2020="" expression:="" request.time="">< timestamp('2020-10-01t00:00:00.000z')="" for="" a="" description="" of="" iam="" and="" its="" features,="" see="" the="" [iam="" developer's="" guide](\="">
