There may be some performance issues using the low-level API, but the overhead should be fairly negligible (though I have seen benchmarks that have stated the contrary). The main advantage in terms of performance is in cold startup speed. The low-level API provides flexibility at the cost of type safety. While I think it's important to understand the low-level API to better grok datastore concepts, you might also want to check out third-party persistence projects such as Objectify, Twig or Slim3 (this is more of a full stack framework).
