Class: Aws::PersonalizeRuntime::Client

Inherits:
Seahorse::Client::Base show all
Defined in:
(unknown)

Overview

An API client for Amazon Personalize Runtime. To construct a client, you need to configure a :region and :credentials.

personalizeruntime = Aws::PersonalizeRuntime::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

See #initialize for a full list of supported configuration options.

Region

You can configure a default region in the following locations:

  • ENV['AWS_REGION']
  • Aws.config[:region]

Go here for a list of supported regions.

Credentials

Default credentials are loaded automatically from the following locations:

  • ENV['AWS_ACCESS_KEY_ID'] and ENV['AWS_SECRET_ACCESS_KEY']
  • Aws.config[:credentials]
  • The shared credentials ini file at ~/.aws/credentials (more information)
  • From an instance profile when running on EC2

You can also construct a credentials object from one of the following classes:

Alternatively, you configure credentials with :access_key_id and :secret_access_key:

# load credentials from disk
creds = YAML.load(File.read('/path/to/secrets'))

Aws::PersonalizeRuntime::Client.new(
  access_key_id: creds['access_key_id'],
  secret_access_key: creds['secret_access_key']
)

Always load your credentials from outside your application. Avoid configuring credentials statically and never commit them to source control.

Instance Method Details

#get_personalized_ranking(options = {}) ⇒ Types::GetPersonalizedRankingResponse

Re-ranks a list of recommended items for the given user. The first item in the list is deemed the most likely item to be of interest to the user.

The solution backing the campaign must have been created using a recipe of type PERSONALIZED_RANKING.

Examples:

Request syntax with placeholder values


resp = client.get_personalized_ranking({
  campaign_arn: "Arn", # required
  input_list: ["ItemID"], # required
  user_id: "UserID", # required
})

Response structure


resp.personalized_ranking #=> Array
resp.personalized_ranking[0].item_id #=> String

Options Hash (options):

  • :campaign_arn (required, String)

    The Amazon Resource Name (ARN) of the campaign to use for generating the personalized ranking.

  • :input_list (required, Array<String>)

    A list of items (itemId\'s) to rank. If an item was not included in the training dataset, the item is appended to the end of the reranked list.

  • :user_id (required, String)

    The user for which you want the campaign to provide a personalized ranking.

Returns:

See Also:

#get_recommendations(options = {}) ⇒ Types::GetRecommendationsResponse

Returns a list of recommended items. The required input depends on the recipe type used to create the solution backing the campaign, as follows:

  • RELATED_ITEMS - itemId required, userId not used

  • USER_PERSONALIZATION - itemId optional, userId required

Campaigns that are backed by a solution created using a recipe of type PERSONALIZED_RANKING use the API.

Examples:

Request syntax with placeholder values


resp = client.get_recommendations({
  campaign_arn: "Arn", # required
  item_id: "ItemID",
  user_id: "UserID",
  num_results: 1,
})

Response structure


resp.item_list #=> Array
resp.item_list[0].item_id #=> String

Options Hash (options):

  • :campaign_arn (required, String)

    The Amazon Resource Name (ARN) of the campaign to use for getting recommendations.

  • :item_id (String)

    The item ID to provide recommendations for.

    Required for RELATED_ITEMS recipe type.

  • :user_id (String)

    The user ID to provide recommendations for.

    Required for USER_PERSONALIZATION recipe type.

  • :num_results (Integer)

    The number of results to return. The default is 25. The maximum is 100.

Returns:

See Also:

#wait_until(waiter_name, params = {}) {|waiter| ... } ⇒ Boolean

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

Basic Usage

Waiters will poll until they are succesful, they fail by entering a terminal state, or until a maximum number of attempts are made.

# polls in a loop, sleeping between attempts client.waiter_until(waiter_name, params)

Configuration

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

# poll for ~25 seconds
client.wait_until(...) do |w|
  w.max_attempts = 5
  w.delay = 5
end

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
client.wait_until(...) do |w|

  # disable max attempts
  w.max_attempts = nil

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

end

Handling Errors

When a waiter is successful, it returns true. When a waiter fails, it raises an error. All errors raised extend from Waiters::Errors::WaiterFailed.

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

Parameters:

  • waiter_name (Symbol)

    The name of the waiter. See #waiter_names for a full list of supported waiters.

  • params (Hash) (defaults to: {})

    Additional request parameters. See the #waiter_names for a list of supported waiters and what request they call. The called request determines the list of accepted parameters.

Yield Parameters:

Returns:

  • (Boolean)

    Returns true if the waiter was successful.

Raises:

  • (Errors::FailureStateError)

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

  • (Errors::TooManyAttemptsError)

    Raised when the configured maximum number of attempts have been made, and the waiter is not yet successful.

  • (Errors::UnexpectedError)

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

  • (Errors::NoSuchWaiterError)

    Raised when you request to wait for an unknown state.

#waiter_namesArray<Symbol>

Returns the list of supported waiters. The following table lists the supported waiters and the client method they call:

Waiter NameClient MethodDefault Delay:Default Max Attempts:

Returns:

  • (Array<Symbol>)

    the list of supported waiters.
