This lecture will cover buffer and memory management strategies in database systems.
Read the following paper:
Chou, Hong-Tai, and David DeWitt. An Evaluation of Buffer Management Strategies for Relational Database Systems. Proceedings of VLDB, 1985, pp. 127-141.
As you read, think about and come to class prepared to answer the following questions:
- How much better is the hot-set model than simple LRU?
- Under what circumstances is LRU a bad idea?
- Why can these techniques be applied in database systems but not operating systems?
