That doesn't say anything about how that "single" BigTable is distributed across nodes. I've have seen reports stating that update operations failed on a certain number of entity groups. This suggests some nodes were failing on which those entity groups where stored. This nothing more, just speculation as I'm not on Google's engineering team, but thinking of a single BigTable as one monolithic entity is naive... :) Maybe someone from the GAE Team can shed light on this matter. > > -- > You received this message because you are subscribed to the Google Groups > "Google App Engine" group. > To post to this group, send email to [email protected]. > To unsubscribe from this group, send email to > [email protected]. > For more options, visit this group at > http://groups.google.com/group/google-appengine?hl=en. > > -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
