Title: Query Deadlock when creating >200 servers at once in sqlalchemy Status in OpenStack Compute (Nova): In Progress Status in Oslo Database library: In Progress Bug description: Query Deadlock when creating >200 servers at once in sqlalchemy. -------- This bug occurred when I test this bug: https://bugs.launchpad.net/nova/+bug/1270725 The original info is logged here: http://paste.openstack.org/show/61534/ -------------- After checking the error-log, we can notice that the deadlock function is 'all()' in sqlalchemy framework. Previously, we use '@retry_on_dead_lock' function to retry requests when deadlock occurs. But it's only available for session deadlock(query/flush/execute). It doesn't cover some 'Query' actions in sqlalchemy. So, we need to add the same protction for 'all()' in sqlalchemy.
