Overview

Deprecated.

Use the long-running operation returned by Admin::Database.database_admin.restore_database instead.

Job

A resource representing the long-running, asynchronous processing of a backup restore. The job can be refreshed to retrieve the restored database object once the operation has been completed.

See Google::Cloud::Spanner::Backup#restore

Examples:

require "google/cloud/spanner"

spanner = Google::Cloud::Spanner.new

instance = spanner.instance "my-instance"
backup = instance.backup "my-backup"
job = backup.restore "my-restored-database"

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

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

#database ⇒ Database?

The database is the object of the operation.

Examples:

require "google/cloud/spanner"

spanner = Google::Cloud::Spanner.new

instance = spanner.instance "my-instance"
backup = instance.backup "my-backup"
job = backup.restore "my-restored-database"

job.done? #=> false
job.reload!
job.done? #=> true
database = job.database

Returns:

  • (Database, nil) —

    The database instance, or nil if the operation is not complete.

end

#done? ⇒ boolean

Checks if the processing of the restore operation is complete.

Examples:

require "google/cloud/spanner"

spanner = Google::Cloud::Spanner.new

instance = spanner.instance "my-instance"
backup = instance.backup "my-backup"
job = backup.restore "my-restored-database"

job.done? #=> false

Returns:

  • (boolean) —

    true when complete, false otherwise.

end

#error ⇒ Google::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

instance = spanner.instance "my-instance"
backup = instance.backup "my-backup"
job = backup.restore "my-restored-database"

  Google::Cloud::Spanner::Status.from_grpc @grpc.error
end

#error? ⇒ boolean

Checks if the processing of the restore operation has errored.

Examples:

require "google/cloud/spanner"

spanner = Google::Cloud::Spanner.new

instance = spanner.instance "my-instance"
backup = instance.backup "my-backup"
job = backup.restore "my-restored-database"

job.error? #=> false

Returns:

  • (boolean) —

    true when errored, false otherwise.

#reload! ⇒ Backup::Job Also known as: refresh!

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

Examples:

require "google/cloud/spanner"

spanner = Google::Cloud::Spanner.new

instance = spanner.instance "my-instance"
backup = instance.backup "my-backup"
job = backup.restore "my-restored-database"

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

instance = spanner.instance "my-instance"
backup = instance.backup "my-backup"
job = backup.restore "my-restored-database"
