Abstract:
Failover of servers over which data is partitioned is disclosed. A first server services client requests for data of a first type, a second server services client requests for data of a second type, and so on. A master server manages notifications from clients and servers as to indication that one of the servers is offline. When the master server receives such a notification, it verifies that the indicated server is in fact offline. If the server is offline, then the master server so notifies the other server. When the first server is offline, one of the other servers may become the failover server, processing client requests for data usually processed by the first server.
