Methods

DataCatalogClient

DataCatalogClient(
    transport=None,
    channel=None,
    credentials=None,
    client_config=None,
    client_info=None,
    client_options=None,
)

Constructor.

Parameters
Name	Description
`channel`	`grpc.Channel` DEPRECATED. A `Channel` instance through which to make calls. This argument is mutually exclusive with `credentials`; providing both will raise an exception.
`credentials`	`google.auth.credentials.Credentials` The authorization credentials to attach to requests. These credentials identify this application to the service. If none are specified, the client will attempt to ascertain the credentials from the environment. This argument is mutually exclusive with providing a transport instance to `transport`; doing so will raise an exception.
`client_config`	`dict` DEPRECATED. A dictionary of call options for each method. If not specified, the default configuration is 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.
`client_options`	`Union[dict, google.api_core.client_options.ClientOptions]` Client options used to set user options on the client. API Endpoint should be set through client_options.

response = client.rename_tag_template_field(name, new_tag_template_field_id)

Parameters
Name	Description
`name`	`str` Required. The name of the tag template. Example: - projects/{project_id}/locations/{location}/tagTemplates/{tag_template_id}/fields/{tag_template_field_id}
`new_tag_template_field_id`	`str` Required. The new ID of this tag template field. For example, `my_new_field`.

search_catalog

search_catalog(scope, query, page_size=None, order_by=None, retry=<_MethodDefault._DEFAULT_VALUE: <object object>>, timeout=<_MethodDefault._DEFAULT_VALUE: <object object>>, metadata=None)

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 subsequentally call Get methods.

Note that searches do not have full recall. There may be results that match your query but are not returned, even in subsequent pages of results. These missing results may vary across repeated calls to search. Do not rely on this method if you need to guarantee full recall.

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

.. rubric:: Example

from google.cloud import datacatalog_v1beta1

client = datacatalog_v1beta1.DataCatalogClient()

TODO: Initialize scope:

scope = {}

TODO: Initialize query:

query = ''

Iterate over all results

for element in client.search_catalog(scope, query): ... # process element ... pass

Alternatively:

Iterate over results one page at a time

for page in client.search_catalog(scope, query).pages: ... for element in page: ... # process element ... pass

Parameters
Name	Description
`scope`	`Union[dict, Scope]` Required. The scope of this search request. If a dict is provided, it must be of the same form as the protobuf message Scope

See `Data Catalog Search Syntax https://cloud.google.com/data-catalog/docs/how-to/search-reference`__ for more information.
`page_size`	`int` The maximum number of resources contained in the underlying API response. If page streaming is performed per- resource, this parameter does not affect the return value. If page streaming is performed per-page, this determines the maximum number of resources in a page.
`order_by`	`str` Specifies the ordering of results, currently supported case-sensitive choices are: - `relevance`, only supports desecending - `last_access_timestamp [asc\|desc]`, defaults to descending if not specified - `last_modified_timestamp [asc\|desc]`, defaults to descending if not specified If not specified, defaults to `relevance` descending.
