A partition checkpoint strategy based on data segment priority is presented to meet the timing constraints of the data and the transaction in embedded real-time main memory database systems(ERTMMDBS) as well as to reduce the number of the transactions missing their deadlines and the recovery time...

张建:[CIDR 2020] Umbra: A Disk-Based System with In-Memory Performance62 赞同 · 0 评论文章 基于磁盘的 DBMS 通常采用 ARIES 风格的日志恢复机制,它可以处理超过内存的数据和事务,可以在多次崩溃的情况下快速恢复,支持 fuzzy checkpoint 等。然而,ARIES 的中心化日志模块开销很高,不能在现代多核 CPU 上扩展...
The checkpoint and data recovery: Recording the checkpoint is important for recovery purposes. The checkpoint identifies the first redo log entry that Oracle will need to process in a recovery situation. All changes related to previous redo log entries have been written to the disk. Checkpoint Proc...
A method and system on failure recovery in a storage system are disclosed. In the storage system, user data streams (e.g., log data) are collected by a scribeh system. The scribeh s
While data for memory optimized tables resides in memory all the time with SQL Server 2014 and 2016's In-Memory OLTP feature, we still need a means to cut down recovery time in case of crash or restart. For disk based table, checkpoint flushes the dirty pages ...
In this paper, we evaluate the applicability of existing checkpoint recovery techniques developed for main-memory DBMS to MMO workloads. Our thorough experimental evaluation uses a detailed simulation model fed with update traces generated synthetically and from a prototype game server. Based on our ...
