I have been testing the the Always On high availability feature in SQL Server 2012 and am finding that there is approximately 15 seconds of down time when the primary server fails over to the secondary server. All SQL queries executed during this time are failing until the failover transition is complete.
Is there any way to get this down to 0 seconds and prevent queries from failing during the failover transition?
In other words, is there a way to get any queries running during the failure to be redirected to the primary server instead of failing... and is there any way to get new db connections to immediately connect to the secondary server instead of failing to connect during the failover transition?
I currently have 2 servers set up in the high availability group.
