In the specific context of MySQL such behavior means that the MySQL Master writes transactions/events to the local binary logs, however it has no idea when the slave(s) will get and process them. Of course such configuration can lead, in case of failover, to some transaction loss since there is no guaranty that the transactions have been transmitted on the standby server(s).
Last week, I attended for the first time the Microsoft TechDays. The 2011 Swiss “edition” took place in Bern. For me it is new challenge, because I newer worked deeply with the Microsoft Database Platform “SQL Server”.
During our test to create a failover clustering with the new function ‘AlwaysOn High Availability’, we had a few difficulties to overcome like the restoring of databases of the secondary cluster node.
In this article, we will just explain you how to avoid it before you encounter the problem.
