Otherwise, as in the case of partial failure, no changes are committed. Two phase commit ensures that state is not changed in a partial manner. Another solution to partial failure is redundancy, or replication. -If one replica of a computation failes, the others may survive and continue. +If one replica of a computation fails, the others may survive and continue. Replication can also be used to improve performance, as in MapReduce and Spark Streaming. Checkpoint and restore has also been implemented as a way to recover from partial failure. By serializing a recent "snapshot" of state to stable storage, recomputing current state is made cheap. |
