Instance Attribute Details

#children ⇒ Array<Types::Mapping>

Only applicable to nested data structures. If you want to change the parent structure, but also one of its children, you can fill out this data strucutre. It is also Mapping, but its FromPath will be the parent's FromPath plus the FromPath from this structure.

For the children part, suppose you have the structure:

{ "FromPath": "OuterStructure", "ToKey": "OuterStructure", "ToType": "Struct", "Dropped": false, "Chidlren": [{ "FromPath": "inner", "ToKey": "inner", "ToType": "Double", "Dropped": false, }] }

You can specify a Mapping that looks like:

{ "FromPath": "OuterStructure", "ToKey": "OuterStructure", "ToType": "Struct", "Dropped": false, "Chidlren": [{ "FromPath": "inner", "ToKey": "inner", "ToType": "Double", "Dropped": false, }] }

Returns:

• (Array<Types::Mapping>)

class Mapping < Struct.new(
  :to_key,
  :from_path,
  :from_type,
  :to_type,
  :dropped,
  :children)
  SENSITIVE = []
  include Aws::Structure
end

#dropped ⇒ Boolean

If true, then the column is removed.

Returns:

• (Boolean)

class Mapping < Struct.new(
  :to_key,
  :from_path,
  :from_type,
  :to_type,
  :dropped,
  :children)
  SENSITIVE = []
  include Aws::Structure
end

#from_path ⇒ Array<String>

The table or column to be modified.

Returns:

• (Array<String>)

end

#from_type ⇒ String

The type of the data to be modified.

Returns:

• (String)

end

#to_key ⇒ String

After the apply mapping, what the name of the column should be. Can be the same as FromPath.

Returns:

• (String)

  :to_key,
  :from_path,
