#get_output(options = {}, &block) ⇒ Types::GetJobOutputOutput

Examples:

Request syntax with placeholder values


job.get_output({
  range: "string",
})

Parameters:

  • options (Hash) (defaults to: {})

    ({})

Options Hash (options):

  • :range (String)

    The range of bytes to retrieve from the output. For example, if you want to download the first 1,048,576 bytes, specify the range as bytes=0-1048575. By default, this operation downloads the entire output.

    If the job output is large, then you can use a range to retrieve a portion of the output. This allows you to download the entire output in smaller chunks of bytes. For example, suppose you have 1 GB of job output you want to download and you decide to download 128 MB chunks of data at a time, which is a total of eight Get Job Output requests. You use the following process to download the job output:

    1. Download a 128 MB chunk of output by specifying the appropriate byte range. Verify that all 128 MB of data was received.

    2. Along with the data, the response includes a SHA256 tree hash of the payload. You compute the checksum of the payload on the client and compare it with the checksum you received in the response to ensure you received all the expected data.

    3. Repeat steps 1 and 2 for all the eight 128 MB chunks of output data, each time specifying the appropriate byte range.

    4. After downloading all the parts of the job output, you have a list of eight checksum values. Compute the tree hash of these values to find the checksum of the entire output. Using the DescribeJob API, obtain job information of the job that provided you the output. The response includes the checksum of the entire archive stored in Amazon S3 Glacier. You compare this value with the checksum you computed to ensure you have downloaded the entire archive content with no errors.

Returns:

#sha256_tree_hashString

For an archive retrieval job, this value is the checksum of the archive. Otherwise, this value is null.

The SHA256 tree hash value for the requested range of an archive. If the InitiateJob request for an archive specified a tree-hash aligned range, then this field returns a value.

If the whole archive is retrieved, this value is the same as the ArchiveSHA256TreeHash value.

This field is null for the following:

  • Archive retrieval jobs that specify a range that is not tree-hash aligned

^ ^

  • Archival jobs that specify a range that is equal to the whole archive, when the job status is InProgress

^ ^

  • Inventory jobs

  • Select jobs

#wait_until(options = {}) {|resource| ... } ⇒ Resource

Deprecated.

Use [Aws::Glacier::Client] #wait_until instead

Note:

The waiting operation is performed on a copy. The original resource remains unchanged.

Waiter polls an API operation until a resource enters a desired state.

Basic Usage

Waiter will polls until it is successful, it fails by entering a terminal state, or until a maximum number of attempts are made.

# polls in a loop until condition is true
resource.wait_until(options) {|resource| condition}

Example

instance.wait_until(max_attempts:10, delay:5) do |instance|
  instance.state.name == 'running'
end

Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. The waiting condition is set by passing a block to #wait_until:

# poll for ~25 seconds
resource.wait_until(max_attempts:5,delay:5) {|resource|...}

Callbacks

You can be notified before each polling attempt and before each delay. If you throw :success or :failure from these callbacks, it will terminate the waiter.

started_at = Time.now
# poll for 1 hour, instead of a number of attempts
proc = Proc.new do |attempts, response|
  throw :failure if Time.now - started_at > 3600
end

  # disable max attempts
instance.wait_until(before_wait:proc, max_attempts:nil) {...}

Handling Errors

When a waiter is successful, it returns the Resource. When a waiter fails, it raises an error.

begin
  resource.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

attempts attempt in seconds invoked before each attempt invoked before each wait

Parameters:

  • options (Hash) (defaults to: {})

    a customizable set of options

Options Hash (options):

  • :max_attempts (Integer) — default: 10

    Maximum number of

  • :delay (Integer) — default: 10

    Delay between each

  • :before_attempt (Proc) — default: nil

    Callback

  • :before_wait (Proc) — default: nil

    Callback

Yield Parameters:

  • resource (Resource)

    to be used in the waiting condition.

Returns:

  • (Resource)

    if the waiter was successful

Raises:

  • (Aws::Waiters::Errors::FailureStateError)

    Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

    yet successful.

  • (Aws::Waiters::Errors::UnexpectedError)

    Raised when an error is encountered while polling for a resource that is not expected.

  • (NotImplementedError)

    Raised when the resource does not
