Could you share with me, how to handle multiple transactions need to be stored in the datastore in your googleAppEngine website?
Let say in situation whereby there is somebody who is buying an item and need to pay using virtual currency, such as poin for instance. In the situation mentioned above, the transactions that might involve as the following: 1. Deduct poin according to the buying amount 2. Insert new buy item transaction 3. Add item into inventory How to apply it so that it will be committed once all the transactions are successfully done, or else it needs to rollback them. Thanks in advance for help. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group. To post to this group, send email to [email protected].
