Remove

The Remove clause may be used to remove attributes from an item or map and to remove elements from a list. See the low-level DynamoDB documentation for more details on the underlying features and capabilities.

Attributes and elements may be removed by using the unary - operator (or the unaryMinus method):

remove {
    -attr["foo"]        // Removes the attribute `foo`
    -attr["baz"]["bar"] // Removes `baz`'s `bar` entry
    -attr["qux"][3]     // Removes `qux`'s element at index `3`
}
