问题 I have read about how boolean columns don't serve much as searching indexes.. But my question is.. if a clustered index, affects the physical arrangement of the records can't it be used to put a type of records, all together (in the same page) so that those page will have less chance of being loaded into memory..

问题 There have been some discussions to use a new flag in madvise() to tell the kernel not to handle page faults in certain memory ranges: lwn.net-1, lwn.net-2 As far as I am able to see, this flag hasn't found its way to the kernel source. What's the current status of this work? 回答1: The community never went forward with MADV_USERFAULT. Instead, a more robust solution called userfaultfd has made its way into the kernel. https://www.kernel.org/doc/Documentation/vm/userfaultfd.txt 来源： https:/
