What is this DataViewer? How do I use this? Eclipse? -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

The data viewer is accessible from the management console in your account: you can see what's in your datastore in all details. regards didier On Jun 10, 5:12 am, Nathan Stiles wrote: > What is this DataViewer?

Oh I see. I was thinking you meant something else. I was imagining something that specifically aids in data object design in eclipse or some other IDE. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

Data schema change is quite easy if you use a MapReduce job. See http://ikaisays.com/2010/07/09/using-the-java-mapper-framework-for-app-engine/ You can still use your JDO instructions in a mapper, even if the mapper performance is not at its best if not using the low-level API. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
