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::RedshiftDataAPIService::Client Overview

An API client for Redshift Data API Service. To construct a client, you need to configure a :region and :credentials.

redshiftdataapiservice = Aws::RedshiftDataAPIService::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::RedshiftDataAPIService::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 #describe_statement(options = {}) ⇒ Types::DescribeStatementResponse

Describes the details about a specific instance when a query was run by the Amazon Redshift Data API. The information includes when the query started, when it finished, the query status, the number of rows returned, and the SQL statement.

#describe_table(options = {}) ⇒ Types::DescribeTableResponse

Describes the detailed information about a table from metadata in the cluster. The information includes its columns. A token is returned to page through the column list. Depending on the authorization method, use one of the following combinations of request parameters:

#execute_statement(options = {}) ⇒ Types::ExecuteStatementOutput

Runs an SQL statement, which can be data manipulation language (DML) or data definition language (DDL). This statement must be a single SQL statement. Depending on the authorization method, use one of the following combinations of request parameters:

#get_statement_result(options = {}) ⇒ Types::GetStatementResultResponse

Fetches the temporarily cached result of an SQL statement. A token is returned to page through the statement results.

#list_databases(options = {}) ⇒ Types::ListDatabasesResponse

List the databases in a cluster. A token is returned to page through the database list. Depending on the authorization method, use one of the following combinations of request parameters:

#list_schemas(options = {}) ⇒ Types::ListSchemasResponse

Lists the schemas in a database. A token is returned to page through the schema list. Depending on the authorization method, use one of the following combinations of request parameters:

#list_statements(options = {}) ⇒ Types::ListStatementsResponse

List of SQL statements. By default, only finished statements are shown. A token is returned to page through the statement list.

#list_tables(options = {}) ⇒ Types::ListTablesResponse

List the tables in a database. If neither SchemaPattern nor TablePattern are specified, then all tables in the database are returned. A token is returned to page through the table list. Depending on the authorization method, use one of the following combinations of request parameters:

#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:
