If a record is fixed length, it never needs to be moved from the page on which it is originally stored.
如果记录是固定长度的,那么就无需将其从存储它的初始页面转移到其他地方。
In other words, rather than rely on a record Length or Delimiter specified on the node itself, one of the broker's parsers should be used to decide where one record ends and the next begins.
换句话说,与依赖节点本身上指定的记录长度或分隔符不同,应该使用代理的解析器之一来决定一个记录从何处结束以及下一个记录从何处开始。
In other situations the total length of a fixed record may be just slightly longer than one-half a 4 KB page, so then only one record can fit on a page.
还有一些情况下,对于一条固定长度的记录,其总长度可能刚好比4 KB的一半大一点点,这时一个页只能容纳一条记录。
