WebAlthough checkpoint-based recovery is able to handle any node failures, it potentially suffers from high recovery latency. The rea-son is two-fold. First, checkpoint-based recovery re-executes the missing workloads over the whole graph, residing in both failed and healthy compute nodes, based on the most recent checkpoint. WebRecovery using Checkpoint. Let’s understand how to recover a failed transaction using checkpoint. The recovery system reads the log file in reverse (from end to start). Recovery system maintains two files: one is redo-list file and second is undo-list file. One or both of these files are used to recover a failed transaction.
