在就索引浪费大量空间，并且由于并发性和ITL（interested transaction list 事务槽）条目的累积问题，空间增长到预期大小的三倍（甚至四倍）的问题发表了一系列简短的贴子之后。我认为为这个系列贴子建个索引以便可以按顺序阅读，是个好主意。
Index Quiz 1 : 问题介绍
Index Quiz 2 : 用block dump来回答问题
Index Explosion : 演示问题
Index Explosion – 2 : 解释问题
Index Explosion – 3 : 解决问题
Index Explosion – 4 : 绕过问题
treedump :研究索引结构的一个有用的选项（尽管有时代价较大)
treedump 2: 关于tree dumps的另一个研究

After wrting a short series of notes on a problem with indexes wasting a lot of space and growing to three (or even four) times the size you might expect due to a problem with concurrency and ITL (interested transaction list) entries accumulating, I thought it would be a good idea to create a little index for the series to make it easier to read them in order:
Index Quiz 1 : An introductory question
Index Quiz 2 : Answering the question with block dumps
Index Explosion : Demonstrating the issue
Index Explosion – 2 : Explaining the problem
Index Explosion – 3 : Solving the problem
Index Explosion – 4 : Working around the problem
treedump : A useful (though sometimes expensive) option for looking into index structures
treedump 2: Another look at tree dumps.
