Abstract
The present disclosure involves systems, software, and computer implemented methods for performing dynamic topology switch in a failover operation. In one example, a failover of a first node is determined. The first node includes a first data server and a first replication server. At least one user application connects to the first data server prior to the failover of the first node. In response to the determined failover, the at least one user application is connected to a second data server of a second node. The second node includes the second data server and a second replication server. Prior to the failover of the first node, a data replication topology of the second node is a remote topology. During the failover, if the first replication server on the first node is down, the data replication topology of the second node is switched from the remote topology to a local topology.
