I have recently ran into a problem after migrating to HRD: My application is a social online game which I have recently migrated from M/S to HR Datastore around 3 weeks ago. Since 2 weeks ago I have started receiving reports from players which their game progress are rolled back suddenly while playing, which progress made in the recent few days are missing. I have verified the problem through data on other entities (in different entity group) that the reports are actually legit and at least several days of progress are actually rolled back (with updates to the entities in the last few days are all missing).
Player's data in the game are retrieved through id ( Player.get_by_id(player_id) ) and because the gap is so large (days) I believe it is not a problem on my code (nowhere in my code cache player's data). It has never happened before for nearly 1 year so I am guessing if it is related to HRD. I remember there was a thread here before which reported data being rolled back on HRD but I can not find it anymore. As you know with AppEngine datastore's distributed nature, it is so hard to monitor this kind of problem to ensure the problem exist. I would like to ask if anyone has ran into this problem as well or suspect that you have had this problem before with your HRD application? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
