The Design and Performance Evaluation of a Lock Manager for a Memory-Resident Database System
In the last fteen years, lock managers for regular disk-based database systems have seen little change. This is not without reason, since traditional memory-resident lock managers have always been much faster than disk-based database storage managers and disk-based database systems had few alternative design options. However, the introduction of memory-resident database systems has created both...
متن کاملA A Scalable Lock Manager for Multicores
Modern implementations of DBMS software are intended to take advantage of high core counts that are becoming common in high-end servers. However, we have observed that several database platforms, including MySQL, Shore-MT, and a commercial system, exhibit throughput collapse as load increases into over-saturation (where there are more request threads than cores), even for a workload with little...
متن کاملLocking and Latching in a Memory-Resident Database System
As part of the Starburst extensible database project developed at the IBM Almaden Research Center, we designed and implemented a memory-resident storage component that co-exists with Star-burst’s diskoriented storage component. The two storage components share the same common services, such as query optimization, transaction management, etc. However, the memory-resident storage component is fas...
متن کاملDistributed Lock Manager
In this paper, we describe Distributed Lock Manager to provide reader with thorough insight into the functionality and evolution of distributed lock manager. Apart from the fact that at present, different solutions for implementation of DLM are available in the market, the insight presented applies to all, in general. We also describe Chubby lock service which is intended to provide coarse-grai...
متن کاملUsing RDMA for Lock Management
In this work, we aim to evaluate different Distributed Lock Management service designs with Remote Direct Memory Access (RDMA). In specific, we implement and evaluate the centralized and the RDMAenabled lock manager designs for fast network settings. Experimental results confirms a couple of hypotheses. First, in the traditional centralized lock manager design, CPU is the bottleneck and bypassi...
