Various systems, methods, and programs embodied in computer-readable
mediums are provided for implementing circular replication among nodes.
In a representative example, a plurality of nodes are arranged in a
circular replication configuration. Each of the nodes has a logfile
indicating storage of a plurality of entries, where each of the nodes
receives the entries from a plurality of external devices. The entries
received by a respective one of the nodes are replicated in the remaining
ones of the nodes via circular replication.
