对于大量的随机写也一样,举一个插入key跨度很大的例子,如7->1000->3->2000 ... 新插入的数据存储在磁盘上相隔很远,会产生大量的随机写IO. 为了克服B+树的弱点,HBase引入了LSM树的概念,即Log-Structured Merge-Trees。 为了更好的说明LSM树的原理,下面举个比较极端的例子: 现在假设有1000个节点的随机key,
root of AVL tree java实现 An AVL tree is a self-balancing binary search tree. In an AVL tree, the heights of the two child subtrees of any node differ by at most one; if at any time they differ by more than one, rebalancing is done to restore this property. Figures 1-4 illustrate...

AVL(Adelson-Velskii 和 Landis)树是带有平衡条件的二叉查找树。在计算机科学中,AVL树是最先发明的自平衡二叉查找树。在AVL树中任何节点的两个子树的高度最大差别为1,所以它也被称为高度平衡树。查找、插入和删除在平均和最坏情况下的时间复杂度都是O(lngn)。增加和删除可能需要通过一次或多次树旋转来重新平衡这...
