I deployed a small app to GAE recently, and a couple of days ago i start getting server errors and noticed that the datastore usage is nearing the limit for the free version ( 1GB ) while i’m not using anywhere near that much for my own data. After some digging, it turns out that the _vac and _ah_session data stores took up most of the 1GB.
As far as i understand it, these are vaadin’s session data, around 80KB-120KB in size for each “record”. I was expecting to see expired data to be deleted automatically, but it seems that this is not the case. Am I doing something wrong or are we supposed to do some manual cleanup with cron jobs or some other method?
Thanks in advance.
