Oracle Rdb's record caching model
Richard Anderson, Gopalan Arun, Richard Frank · 1998
In this paper we present a more efficient record based caching model than the conventional page (disk block) based scheme. In a record caching model, individual records are stored together in a section of shared memory to form the cache. Traditional relational database systems have individual pages that are stored together in shared memory to form the cache and records are then extracted from these pages on demand. The record cache model has better memory utilization than the page model and also helps reduce overheads like page fetches/writes, page locks and code path.
