Accessing the datastore remotely with remote_api - Google App Engine - Google Code - 0 views

  • The remote_api module consists of two parts: A 'handler', which you install on the server to handle remote datastore requests, and a 'stub', which you set up on the client to translate datastore requests into calls to the remote handler. remote_api works at the lowest level of the datastore, so once you've set up the stub, you don't have to worry about the fact that you're operating on a remote datastore: With a few caveats, it works exactly the same as if you were accessing the datastore directly.
  • Note that the handler specifies "login: admin". This is extremely important, since we don't want to give just anyone unfettered access to our datastore!
  • Since you're accessing the datastore over HTTP, there's a bit more overhead and latency than when you access it locally. In order to speed things up and decrease load, try to limit the number of round-trips you do by batching gets and puts, and fetching batches of entities from queries. This is good advice not just for remote_api, but for using the datastore in general, since a batch operation is only considered to be a single Datastore operation
