发帖数: 1565 | 10 Mostly the 拉球的稳定性 for returning serving balls.
For 连续拉的consistency: it becomes the footwork, and after the first loop
of an back-spin ball, it most likely top spin instead of backspin unless it
comes from a chopper.
Why 拉球的稳定性 is important: becasue the coming ball has different spins
and speeds. |

发帖数: 1578 | 11 能解释一下吗？
"My previous RPB looping has a factor, i.e., lifting forward factor due to
handling under-spin balls, which factor is wrong and which is the reason of
un-consistency because lifting will cause errors due to the different speed
and spin of the coming ball so that it is difficult to produce a perfect
lifting to counter the back-spin." |

match? It's still mental, mentally got tight, mentally not as confident,
mentally thought I should do something more (change) with the shot. All
those caused the lack of footwork during the match, lack of footwork yield
lack of consistency. But it still started with mental. |

发帖数: 5958 | 31 quorum read/write 延时会成倍增加啊。其实只要quorum write就行了，但那样也有点
不值得，毕竟只要绝大部分时候consistent就行。但是因为写和读之间的时间非常短，
怕到不了eventual那一步，那样的话inconsistent就会成为常态。
话说有人知道eventual是几秒吗？貌似facebook也是受不了这个eventual改用别的了。 |

发帖数: 8232 | 33 问题是你写的consistency level 是什么？如果是ONE. 如果写向A那不能保证B会有你
的数据， 如果A down 了，可能你就从B读不到数据。
避免这种情况，就要用quorum write. 你要等到两个node 都ack 了，你的写才是成功
的。
read 类似道理。 |

发帖数: 2416 | 42 关键就是fail以前的最后一个transaction总是不确定的。不论你采用什么机制，ack,
ack of ack, ack of ack of ack。。。
这是一个很简单的逻辑问题。单机都存在这个问题。这还是在不追求性能的条件的理论
最优解。多机partitioning只不过放大了这个问题。
如果追求性能，允许异步通信，那么单机不确定的数量会大于1。
刚看了jepsen，zookeeper也会出现fail以后elect多个master的问题。
因此，简化版本，两台单机client/server transaction。也必须两边记录journal log
。fail以后要有个两边对账的机制，才能保证100的consistency。
事实上，我没看到有这么做的。 |

w***g
发帖数: 5958 | 44 我觉得你说的这个超过ACID的范畴了。
一个transaction玩了，client说commit，server成功执行，并且执行确认操作(ack)，
到此位置是consistency和durability的界限。如果因为什么原因client没有收到这个
ack，transaction也算是成功了。不然如你所说，ack of ack ...起来没完没了了，
就变成黑暗森林了。ack丢失的情况下要保证系统成功运行，得有强壮的业务逻辑才行。

I took record of stock price every trading day, for each tuple in the db, I
have 3 attributes:
date, previous_day_close_price, close_price
and I want to check if the system is consistent, if I see something like:

2010-07-14, 5.17, 5.21
2010-07-15, 5.21, *5.14
2010-07-16, *5.10, 5.06
