为什么要使用FTWRL   MySQL dba在日常工作中,数据备份绝对是工作频度最高的工作内容之一.当你使用逻辑方式进行备份(mydumper,mysqldump)或物理方式进行备份(percona-xtrabackup),为了保证数据的一致性,这两种备份方式都会在备份过程中执行 flush table with read lock 这个命令(**以下简称为FTWRL**),通过执行FTWRL,来对事务和非事务表来加table level级别的共享锁,取得此时的gtid或者binlog偏移量,…

Physical(Raw) and Logical Backup: 1.Physical backups consist of raw copies of the directories and files that store database contents. This type of backup is suitable for large, important databases that need to be recovered quickly. 2.Logical backups…

▶ 有关将一棵二叉树转化为二位表的题目,一模一样的套路出了四道题 ▶ 第 102 题,简单的转化,[ 3, 9, 20, null, null, 15, 7 ] 转为 [ [ 15, 7 ] , [ 9, 20 ] , [ 3 ] ] ● 自己的代码,6 ms,先根序遍历,最快的解法算法与之相同 class Solution { public: void visit(TreeNode* root, vector<vector<int>>& table, int level)…

PURPOSE The purpose of this document is to give a quick guide for using RMAN on RAC databases. We will follow this points: 1. Verify the database mode and archive destination.2. Verify connectivity using sqlnet for target and catalog.3. Determine the…
