MagnetoDB/specs/all old for put item

"ALL_OLD" return value for "put_item" method

Launchpad: [1]

While using "put_item" request we do not have any information about presence of item with same key as we put. According to DynamoDB API we must have an ability to pass "ReturnValue": "ALL_OLD" in put_item request, so replaced item will be returned in response.
