发帖数: 120 | 1 我说REHASH, 然后他问我第一个HASH后怎么知道在那个地址的是你要的值还是另一个值
，我说直接比较啊，不是就REHASH，那个阿三说什么HASH只能比较对KEY 进行操作，没
办法比较VALUE什么的，把我批得体无完肤，我还真没弄懂了 如果只能对HASH后的
VALUE 找值，怎么判断第一轮的是我想要的还是第二轮是我想要的 |

发帖数: 6599 | 2 嗯，的确没办法比较。
这属于collision, 解决的方法是在同一个bucket 里面用linked list，然后再
linkedlist里面逐一比较value
他大概再提示你 rehash不work吧
rehash是当hash 太满的时候，太多bucket 会有一个常常的linked list，那么大量的
操作就不是O(1) 而是O(k), k是linkedlist的长度
所以需要扩大hash array的size，然后重新插入value |

rehash 的过程可以理解为把现有的所有数据插到一个新的hash table.之后， 再新的
hash table中找。 |
|
b******e
发帖数: 120 | 5 他的意思是有两个值，他们用第一个HASH FUNCTION 都对应一个KEY，那么对后加入的
用REHASH 找到另一个KEY或者说地址存放，那么在SEARCH 第二个值的时候，都会开始
用第一个HASH FUNCTION， 那么你怎么判断第一个HASH FUNCTION 找到的那个KEY是第
一个值对应的还是第二个值对应的，我说要比较，他说没有办法比较，因为算出来的
KEY是一样的 |

发帖数: 2330 | 6 这都搞笑呢吧。。。
hash table，hash（key）是作为index，插入对应bucket；
query的时候，找到对应的bucket，然后查找对应的key。。。
rehash（应该叫double hashing）只是放到另一个bucket
query的时候先用第一个hash，找到bucket，找key；没有，第二个hash，第二个bucket
，找key，有，return，没有，拉倒。。。
什么跟什么，阿三是生物学毕业的码工吧。。。 |

If the initial loading time is not counted and your string key is db id type
of string, then hashmap might be fine since both rehashing and collision
will not be issue any more.
But according to the original post, it seems that we are talking about
building the hashmap over the time on the fly with random and big strings as
the key. if so, rehashing and collision will be issues. |

db id type string (especially surrogate id), due to the constraint applied,

rehashing is another issue because of the way how the default implementation

我觉得也不一定吧，看你hashtable是怎么实现了。如果是chainning的话，是比bst多

Hashtable还有一个问题是如果你不断的往里加东西，接近满了的时候性能就下降了，
需要rehash。 |
