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)

  :from_path,

  :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)
