Schemafinder starts up the local Mnesia and joins a schema defined at other nodes as discovered by the indicated nodefinder strategy and the indicated schemafinder group. It also provides a mechanism for identifying and pruning mnesia nodes that are permanantly out of service. Finally it allows optional reuse of the Mnesia directory during shutdown and guards against joining with a stale schema after having been removed (which, if not guarded against, leads to undefined behavior).

Combined these capabilities greatly ease administration and maintenance of Mnesia in a dynamic environment such as EC2.

Unfortunately, schemafinder currently does not assist in recovering from networking partitioning.

Another Dukes of Erl release.
