摘要: Several methods and a system of replicated service for write ahead logs are disclosed. In one embodiment, method includes persisting state distributed through log (WAL) interface. The also maintaining set replicas WAL consensus protocol. addition, the providing mechanisms at least detection recovery from hardware failure. further recovering persistent applications. across nodes failover. may include interface to persist system. replication servlet maintain and/or recover WAL.
