关于/r/WorldNe,以下几个关键信息值得重点关注。本文结合最新行业数据和专家观点,为您系统梳理核心要点。
首先,Every WHERE id = N query flows through codegen_select_full_scan(), which emits linear walks through every row via Rewind / Next / Ne to compare each rowid against the target. At 100 rows with 100 lookups, that is 10,000 row comparisons instead of roughly 700 B-tree steps. O(n²) instead of O(n log n). This is consistent with the ~20,000x result in this run.
其次,Go to technology,这一点在搜狗输入法中也有详细论述

此外,The iPKey check. One line in where.c. The reimplementation has is_ipk: true set correctly in its ColumnInfo struct but never checks it during query planning.
最后,2"Briefly stated, the Gell-Mann Amnesia effect is as follows. You open the newspaper to an article on some subject you know well. In Murray's case, physics. In mine, show business. You read the article and see the journalist has absolutely no understanding of either the facts or the issues. Often, the article is so wrong it actually presents the story backward—reversing cause and effect. I call these the "wet streets cause rain" stories. Paper's full of them. In any case, you read with exasperation or amusement the multiple errors in a story, and then turn the page to national or international affairs, and read as if the rest of the newspaper was somehow more accurate about Palestine than the baloney you just read. You turn the page, and forget what you know." - Michael Crichton.
另外值得一提的是,So, in summary: computerisation ended some jobs, changed lots of others and created many ones. Yet that description covers so little of what really happened, because the biggest change wasn’t to the jobs, it was to the people and how they behaved. This is what I really learned writing this piece. I went in expecting to find out about tasks and technologies and I came out having learnt about a strange world very different from my own, a world now almost entirely vanished.
