Scalaris

Key Features

* Scalaris uses a structured overlay with a non-blocking Paxos commit protocol for transaction processing with strong consistency over replicas. Scalaris is implemented in Erlang. * Scalaris uses quorum algorithms that assume a crash-stop failure model for processes. A precondition of such systems is, that a majority of the replicas of an item is always available. * As a management-server a Scalaris node maintains a list of all Scalaris nodes in the system and provides a web-interface for debugging - including different plots of the ring. It has no administrative tasks. A ring could be created without one. * When starting a Scalaris ring we have to mark exactly one node as the first node. This node will not try contacting any other node and simply wait for connections. It thus creates a new ring.
