Dataproc Metastore V1 API - Class Google::Cloud::Metastore::V1::DataprocMetastoreFederation::Client (v0.4.0)

Reference documentation and code samples for the Dataproc Metastore V1 API class Google::Cloud::Metastore::V1::DataprocMetastoreFederation::Client.

Client for the DataprocMetastoreFederation service.

Configures and manages metastore federation services. Dataproc Metastore Federation Service allows federating a collection of backend metastores like BigQuery, Dataplex Lakes, and other Dataproc Metastores. The Federation Service exposes a gRPC URL through which metadata from the backend metastores are served at query time.

The Dataproc Metastore Federation API defines the following resource model:

  • The service works with a collection of Google Cloud projects.
  • Each project has a collection of available locations.
  • Each location has a collection of federations.
  • Dataproc Metastore Federations are resources with names of the form: projects/{project_number}/locations/{location_id}/federations/{federation_id}.

Methods

.configure

def self.configure() { |config| ... } -> Client::Configuration

Configure the DataprocMetastoreFederation Client class.

See Configuration for a description of the configuration fields.

Yields
  • (config) — Configure the Client client.
Yield Parameter
Returns
Example 
# Modify the configuration for all DataprocMetastoreFederation clients
::Google::Cloud::Metastore::V1::DataprocMetastoreFederation::Client.configure do |config|
  config.timeout = 10.0
end

#configure

def configure() { |config| ... } -> Client::Configuration

Configure the DataprocMetastoreFederation Client instance.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on Client.configure.

See Configuration for a description of the configuration fields.

Yields
  • (config) — Configure the Client client.
Yield Parameter
Returns

#create_federation

def create_federation(request, options = nil) -> ::Gapic::Operation
def create_federation(parent: nil, federation_id: nil, federation: nil, request_id: nil) -> ::Gapic::Operation

Creates a metastore federation in a project and location.

Overloads 
def create_federation(request, options = nil) -> ::Gapic::Operation
Pass arguments to create_federation via a request object, either of type CreateFederationRequest or an equivalent Hash.
Parameters
  • request (::Google::Cloud::Metastore::V1::CreateFederationRequest, ::Hash) — A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.
  • options (::Gapic::CallOptions, ::Hash) — Overrides the default settings for this call, e.g, timeout, retries, etc. Optional. 
def create_federation(parent: nil, federation_id: nil, federation: nil, request_id: nil) -> ::Gapic::Operation
Pass arguments to create_federation via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).
Parameters
  • parent (::String) — Required. The relative resource name of the location in which to create a federation service, in the following form:

    projects/{project_number}/locations/{location_id}.

  • federation_id (::String) — Required. The ID of the metastore federation, which is used as the final component of the metastore federation's name.

    This value must be between 2 and 63 characters long inclusive, begin with a letter, end with a letter or number, and consist of alpha-numeric ASCII characters or hyphens.

  • federation (::Google::Cloud::Metastore::V1::Federation, ::Hash) — Required. The Metastore Federation to create. The name field is ignored. The ID of the created metastore federation must be provided in the request's federation_id field.
  • request_id (::String) — Optional. A request ID. Specify a unique request ID to allow the server to ignore the request if it has completed. The server will ignore subsequent requests that provide a duplicate request ID for at least 60 minutes after the first request.

    For example, if an initial request times out, followed by another request with the same request ID, the server ignores the second request to prevent the creation of duplicate commitments.

    The request ID must be a valid UUID A zero UUID (00000000-0000-0000-0000-000000000000) is not supported.

Yields
  • (response, operation) — Access the result along with the RPC operation
Yield Parameters
  • response (::Gapic::Operation)
  • operation (::GRPC::ActiveCall::Operation)
Returns
  • (::Gapic::Operation)
Raises
  • (::Google::Cloud::Error) — if the RPC is aborted.

Updates the fields of a federation.

Overloads 
def update_federation(request, options = nil) -> ::Gapic::Operation
Pass arguments to update_federation via a request object, either of type UpdateFederationRequest or an equivalent Hash.
Parameters
  • request (::Google::Cloud::Metastore::V1::UpdateFederationRequest, ::Hash) — A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

Parameters
  • update_mask (::Google::Protobuf::FieldMask, ::Hash) — Required. A field mask used to specify the fields to be overwritten in the metastore federation resource by the update. Fields specified in the update_mask are relative to the resource (not to the full request). A field is overwritten if it is in the mask.
  • federation (::Google::Cloud::Metastore::V1::Federation, ::Hash) — Required. The metastore federation to update. The server only merges fields in the service if they are specified in update_mask.

    The metastore federation's name field is used to identify the metastore service to be updated.

  • request_id (::String) — Optional. A request ID. Specify a unique request ID to allow the server to ignore the request if it has completed. The server will ignore subsequent requests that provide a duplicate request ID for at least 60 minutes after the first request.

    For example, if an initial request times out, followed by another request with the same request ID, the server ignores the second request to prevent the creation of duplicate commitments.

    The request ID must be a valid UUID A zero UUID (00000000-0000-0000-0000-000000000000) is not supported.

Yields
  • (response, operation) — Access the result along with the RPC operation
