Segmented fuzzy checkpointing for main memory databases
Jun-Lin Lin, Margaret H. Dunham · 1996
Due to little interference with other database activities, fuzzy checkpointing has been shown to be quite suitable for Main Memory Databases. This paper presents a new fuzzy checkpointing approach called Segmented Fuzzy Checkpointing (SFC), which can greatly reduce the log processing time during restart without or only slightly degrading the system performance. SFC uses a moving window to locate a more efficient redo-point than other fuzzy checkpointing approaches. The concept of SFC is simple and flexible. Our analytical result shows that SFC speeds up the restart operation with little overhead.
