I need to write code so that a user has a counter. This counter can be read, increase, and decrease. This counter is mission critical so I will use the high replication datastore.
So lets say I create a counter entity which has a user entity as the ancestor. I increase the counter value and store the value. Almost simultaneously I get another request to read the counter. I get the entity from the datastore , using the correct ancestor chain, and I read the value. Is it possible that these two values will be different? If so, is there anyway way to prevent this from happening? -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
