Which replication topologies are supported by ScaleArc?
ScaleArc supports all possible replication topologies used by MySQL, SQL Server, and Oracle, including master/slave, multi-master, multi-master/multi-slave, Percona xtraDB Galera, NDB cluster, peer to peer, log shipping, SQL mirroring, AlwaysOn, Oracle RAC, or even shared disk databases. ScaleArc is replication-technology agnostic. ScaleArc also has a built-in replication monitor that makes sure all servers are in sync at a given time. If a server falls out of sync, ScaleArc will reduce the load on that server to give it the opportunity to recover. If the server fails to recover and falls further out of sync, ScaleArc can be configured to stop sending queries to that server.
