Client — AWS SDK for Ruby V2

You are viewing documentation for version 2 of the AWS SDK for Ruby. Version 3 documentation can be found here.

Class: Aws::Kafka::Client Overview

An API client for Managed Streaming for Kafka. To construct a client, you need to configure a :region and :credentials.

kafka = Aws::Kafka::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:

Go here for a list of supported regions.

Credentials

Default credentials are loaded automatically from the following locations:

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:

creds = YAML.load(File.read('/path/to/secrets'))

Aws::Kafka::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.

Methods included from Seahorse::Client::HandlerBuilder

#handle, #handle_request, #handle_response

Instance Method Details #delete_cluster(options = {}) ⇒ Types::DeleteClusterResponse

Deletes the MSK cluster specified by the Amazon Resource Name (ARN) in the request.

#delete_configuration(options = {}) ⇒ Types::DeleteConfigurationResponse

Deletes the specified MSK configuration. The configuration must be in the ACTIVE or DELETE_FAILED state.

#describe_cluster(options = {}) ⇒ Types::DescribeClusterResponse

Returns a description of the MSK cluster whose Amazon Resource Name (ARN) is specified in the request.

#tag_resource(options = {}) ⇒ Struct

Adds tags to the specified MSK resource.

#untag_resource(options = {}) ⇒ Struct

Removes the tags associated with the keys that are provided in the query.

#update_broker_count(options = {}) ⇒ Types::UpdateBrokerCountResponse

Updates the number of broker nodes in the cluster. You can use this operation to increase the number of brokers in an existing cluster. You can't decrease the number of brokers.

#update_monitoring(options = {}) ⇒ Types::UpdateMonitoringResponse

Updates the monitoring settings for the cluster. You can use this operation to specify which Apache Kafka metrics you want Amazon MSK to send to Amazon CloudWatch. You can also specify settings for open monitoring with Prometheus.

#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:
