Job

A resource representing the long-running, asynchronous processing of an instance create or update operation. The job can be refreshed to retrieve the instance object once the operation has been completed.

See Project#create_instance and #update.

Client#create_instance instead.

Examples:

require "google/cloud/spanner"

spanner = Google::Cloud::Spanner.new

job = spanner.create_instance "my-new-instance",
                              name: "My New Instance",
                              config: "regional-us-central1",
                              nodes: 5,
                              labels: { production: :env }

job.done? #=> false
job.reload! # API call
job.done? #=> true

if job.error?
  status = job.error
else
  instance = job.instance
end

#done?boolean

Checks if the processing of the instance operation is complete.

Examples:

require "google/cloud/spanner"

spanner = Google::Cloud::Spanner.new

                              name: "My New Instance",
                              config: "regional-us-central1",
                              nodes: 5,
                              labels: { production: :env }

job.done? #=> false

Returns:

  • (boolean)

    true when complete, false otherwise.

#errorGoogle::Cloud::Spanner::Status?

The status if the operation associated with this job produced an error.

Examples:

require "google/cloud/spanner"

spanner = Google::Cloud::Spanner.new

job = spanner.create_instance "my-new-instance",
                              name: "My New Instance",
                              config: "regional-us-central1",

end

#error?boolean

Checks if the processing of the instance operation has errored.

Examples:

require "google/cloud/spanner"

spanner = Google::Cloud::Spanner.new

job = spanner.create_instance "my-new-instance",
                              name: "My New Instance",

spanner = Google::Cloud::Spanner.new

job = spanner.create_instance "my-new-instance",
                              name: "My New Instance",

end

#reload!Google::Cloud::Spanner::Instance::Job Also known as: refresh!

Reloads the job with current data from the long-running, asynchronous processing of an instance operation.

Examples:

require "google/cloud/spanner"

spanner = Google::Cloud::Spanner.new

job = spanner.create_instance "my-new-instance",
                              name: "My New Instance",
                              config: "regional-us-central1",

                              labels: { production: :env }

job.done? #=> false
job.reload! # API call
job.done? #=> true

end

#wait_until_done!Object

Reloads the job until the operation is complete. The delay between reloads will incrementally increase.

Examples:

require "google/cloud/spanner"

spanner = Google::Cloud::Spanner.new

job = spanner.create_instance "my-new-instance",
                              name: "My New Instance",
                              config: "regional-us-central1",
                              nodes: 5,
                              labels: { production: :env }
