Instance Attribute Details

#inputs ⇒ Array<String>

The data inputs identified by their node names. You can associate a table name with each input node to use in the SQL query. The name you choose must meet the Spark SQL naming restrictions.

Returns:

• (Array<String>)

# File 'lib/aws-sdk-glue/types.rb', line 20058

class SparkSQL < Struct.new(
  :name,
  :inputs,
  :sql_query,
  :sql_aliases,
  :output_schemas)
  SENSITIVE = []
  include Aws::Structure
end

#name ⇒ String

The name of the transform node.

Returns:

• (String)

# File 'lib/aws-sdk-glue/types.rb', line 20058

class SparkSQL < Struct.new(
  :name,
  :inputs,
  :sql_query,
  :sql_aliases,
  :output_schemas)
  SENSITIVE = []
  include Aws::Structure
end

#output_schemas ⇒ Array<Types::GlueSchema>

Specifies the data schema for the SparkSQL transform.

Returns:

• (Array<Types::GlueSchema>)

# File 'lib/aws-sdk-glue/types.rb', line 20058

class SparkSQL < Struct.new(
  :name,
  :inputs,
  :sql_query,
  :sql_aliases,
  :output_schemas)
  SENSITIVE = []
  include Aws::Structure
end

#sql_aliases ⇒ Array<Types::SqlAlias>

A list of aliases. An alias allows you to specify what name to use in the SQL for a given input. For example, you have a datasource named “MyDataSource”. If you specify ‘From` as MyDataSource, and `Alias` as SqlName, then in your SQL you can do:

‘select * from SqlName`

and that gets data from MyDataSource.

Returns:

• (Array<Types::SqlAlias>)

# File 'lib/aws-sdk-glue/types.rb', line 20058

class SparkSQL < Struct.new(
  :name,
  :inputs,
  :sql_query,
  :sql_aliases,
  :output_schemas)
  SENSITIVE = []
  include Aws::Structure
end

#sql_query ⇒ String

A SQL query that must use Spark SQL syntax and return a single data set.

Returns:

• (String)

# File 'lib/aws-sdk-glue/types.rb', line 20058

class SparkSQL < Struct.new(
  :name,
  :inputs,
  :sql_query,
  :sql_aliases,
  :output_schemas)
