大数据的内存性能

这篇文章真的很有趣-使用Buffer Manager为传统数据库系统设计的指针陷入困境，以与内存数据库竞争较小的数据集：

Seems I "accidentally" implemented a similar mechanism for https://sirix.org as I'm setting in-memory page references on a cache miss and explicitly set them to null, once the Buffer Manager has to evict entries :-) However as I'm using object instances as keys I can simply set the reference to null instead of using another Cache for a child to parent mapping. I'll see if I can simply cache the Java hashCode values in an instance field to further improve performance a bit.

周末愉快 ：-）
