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']andENV['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.
#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 -
itemIdrequired,userIdnot used -
USER_PERSONALIZATION -
itemIdoptional,userIdrequired
Campaigns that are backed by a solution created using a recipe of type PERSONALIZED_RANKING use the API.
#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
#waiter_names ⇒ Array<Symbol>
Returns the list of supported waiters. The following table lists the supported waiters and the client method they call:
| Waiter Name | Client Method | Default Delay: | Default Max Attempts: |
|---|
