摘要：Most the major commercial database systems were designed in an era of small memories and uniprocessormachines. The only realistic design option was to store data on disk and bring disk pages into memory as neededfor processing. This model served us well for many years but the world has changed. Today, a server with 32processor cores and 1TB of memory costs as little as $50K. The majority of OLTP databases fit entirely in 1TBand even the largest OLTP databases can keep the active working set in memory. To take full advantage ofthis class of machines it is not sufficient to merely increase the size of the buffer pool. The architecture of thedatabase system needs to be reconsidered from the ground up
