::Google::Cloud::Dataflow::V1beta3::Messages::Rest::Client.configure do |config|
  config.timeout = 10.0
end

Yields:

  • (config) —

    Configure the Client client.

Instance Method Details

#configure {|config| ... } ⇒ Client::Configuration

Configure the Messages 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 configure.

See Configuration for a description of the configuration fields.

Yields:

  • (config) —

    Configure the Client client.

#list_job_messages(request, options = nil) ⇒ ::Google::Cloud::Dataflow::V1beta3::ListJobMessagesResponse #list_job_messages(project_id: nil, job_id: nil, minimum_importance: nil, page_size: nil, page_token: nil, start_time: nil, end_time: nil, location: nil) ⇒ ::Google::Cloud::Dataflow::V1beta3::ListJobMessagesResponse

Request the job status.

To request the status of a job, we recommend using projects.locations.jobs.messages.list with a regional endpoint. Using projects.jobs.messages.list is not recommended, as you can only request the status of jobs that are running in us-central1.

Examples:

Basic example

require "google/cloud/dataflow/v1beta3"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Dataflow::V1beta3::Messages::Rest::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Dataflow::V1beta3::ListJobMessagesRequest.new

# Call the list_job_messages method.
result = client.list_job_messages request

# The returned object is of type Gapic::PagedEnumerable. You can iterate
# over elements, and API calls will be issued to fetch pages as needed.
result.each do |item|
  # Each element is of type ::Google::Cloud::Dataflow::V1beta3::JobMessage.
  p item
end

Overloads:

  • #list_job_messages(request, options = nil) ⇒ ::Google::Cloud::Dataflow::V1beta3::ListJobMessagesResponse

    Pass arguments to list_job_messages via a request object, either of type ListJobMessagesRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::Dataflow::V1beta3::ListJobMessagesRequest, ::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) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries etc. Optional.

  • #list_job_messages(project_id: nil, job_id: nil, minimum_importance: nil, page_size: nil, page_token: nil, start_time: nil, end_time: nil, location: nil) ⇒ ::Google::Cloud::Dataflow::V1beta3::ListJobMessagesResponse

    Pass arguments to list_job_messages 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:

    • project_id (::String) (defaults to: nil) —

      A project id.

    • job_id (::String) (defaults to: nil) —

      The job to get messages about.

    • minimum_importance (::Google::Cloud::Dataflow::V1beta3::JobMessageImportance) (defaults to: nil) —

      Filter to only get messages with importance >= level

    • page_size (::Integer) (defaults to: nil) —

      If specified, determines the maximum number of messages to return. If unspecified, the service may choose an appropriate default, or may return an arbitrarily large number of results.

    • page_token (::String) (defaults to: nil) —

      If supplied, this should be the value of next_page_token returned by an earlier call. This will cause the next page of results to be returned.

    • start_time (::Google::Protobuf::Timestamp, ::Hash) (defaults to: nil) —

      If specified, return only messages with timestamps >= start_time. The default is the job creation time (i.e. beginning of messages).

    • end_time (::Google::Protobuf::Timestamp, ::Hash) (defaults to: nil) —

      Return only messages with timestamps < end_time. The default is now (i.e. return up to the latest messages available).

    • location (::String) (defaults to: nil) —

      The regional endpoint that contains the job specified by job_id.

Yields:

  • (result, operation) —

    Access the result along with the TransportOperation object

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the REST call is aborted.
