Class: Aws::Kafka::Client

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

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:

  • 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::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.

#initialize(options = {}) ⇒ Aws::Kafka::Client

Constructs an API client.

Options Hash (options):

  • :access_key_id (String)

    Used to set credentials statically. See Plugins::RequestSigner for more details.

  • :active_endpoint_cache (Boolean)

    When set to true, a thread polling for endpoints will be running in the background every 60 secs (default). Defaults to false. See Plugins::EndpointDiscovery for more details.

  • :convert_params (Boolean) — default: true

    When true, an attempt is made to coerce request parameters into the required types. See Plugins::ParamConverter for more details.

  • :endpoint_cache_poll_interval (Integer)

    When :endpoint_discovery and :active_endpoint_cache is enabled, Use this option to config the time interval in seconds for making requests fetching endpoints information. Defaults to 60 sec. See Plugins::EndpointDiscovery for more details.

#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.

Examples:

Request syntax with placeholder values


resp = client.update_broker_count({
  cluster_arn: "__string", # required
  current_version: "__string", # required
  target_number_of_broker_nodes: 1, # required
})

Response structure


resp.cluster_arn #=> String
resp.cluster_operation_arn #=> String

Options Hash (options):

  • :cluster_arn (required, String)
  • :current_version (required, String)

    The current version of the cluster.

  • :target_number_of_broker_nodes (required, Integer)

    The number of broker nodes that you want the cluster to have after this operation completes successfully.

Returns:

#update_broker_storage(options = {}) ⇒ Types::UpdateBrokerStorageResponse

Updates the EBS storage associated with MSK brokers.

Examples:

Request syntax with placeholder values


resp = client.update_broker_storage({
  cluster_arn: "__string", # required
  current_version: "__string", # required
  target_broker_ebs_volume_info: [ # required
    {
      kafka_broker_node_id: "__string", # required

resp.cluster_operation_arn #=> String

Options Hash (options):

  • :cluster_arn (required, String)
  • :current_version (required, String)

    The version of cluster to update from. A successful operation will then generate a new version.

  • :target_broker_ebs_volume_info (required, Array<Types::BrokerEBSVolumeInfo>)

    Describes the target volume size and the ID of the broker to apply the update to.

    The value you specify for Target-Volume-in-GiB must be a whole number that is greater than 100 GiB.

    The storage per broker after the update operation can\'t exceed 16384 GiB.

Returns:

#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:

Returns:

  • (Array<Symbol>)

    the list of supported waiters.
