Abstract
The impact of updating policy and access pattern on the performance of post-crash log processing with a fuzzy checkpointing main memory database (MMDB) is discussed. The problem of restoring the database to a consistent state and several algorithms for post-crash log processing under the various updating alternatives are reviewed. Using an analytic model, the checkpoint behavior and post-crash log processing performance of these algorithms are examined. Analytic results show that deferred updating always takes less time to process the log after a crash
