Problems Solving

• Support get struct by keyword from cache.

defmodule API do
  @decorate cache_object(User)
  def get_user(conds) do
    ...
    {:ok, user}
  end
end
# pass keyword to get object.
API.get_user([name: "name", addr: "addr"])

• Delete dirty structs when its deep nested struct updated/deleted.

%User{
  id: 1, 
  user_name: "u_name", 
  role: %Role{id: 2, role_name: "r_name"}
}

For above sample struct, role struct deleted/upadted, user struct will be deleted too.
