Hi, thanks for your reply. I cannot believe that datastore is not able to handle many write requests simultaneously. Where did you get this information? Of course I'm not writing to the same entity groups, just plain entities. Any insight would be highly appreciated! My code is quite simpe, just writing to the datastore from concurrent tasks using low-level api.
