Label:4.4 Stream-based and file-based recoveryLife is not always black or white; sometimes there are some shades of gray. For some scenarios, stream replication may be just right. In other cases, file-based replication and PITR are what you need. However, there are also many cases where you need both stream replication and file-based

The replication latency caused by the mutual blocking of MySQL 5.7 concurrent replication and mysqldump. The MySQL BINLOG and show processlist commands were originally two transactions that could not be reached by the client. However, in the recent troubleshooting, it was found that there was a serious replication delay between the master database and slave datab

Title Link: http://www.lydsy.com:808/JudgeOnline/problem.php?id=1103The main idea: to give you a tree, just start all the tree edge Benquan are 1, and constantly change some of the edge of the right to 0, in the meantime asked you a point to the root node between the path of Benquan and.This question is similar to the apple Tree of POJ ...First DFS generates the topological order of the entire tree, DFS whe

The nearest ancestor of any two points on the tree must be the least depth of the shortest path of the two nodes.For example, in nodes 7 and 5, the shortest path is 7--4--1--5, and the smallest point on the path is node 1, with a depth of 1. Node 1 is the LCA for nodes 7 and 5.Therefore, to find any two-node LCA, we need to find the shortest path above, and then find the least depth point in the shortest path. And this is what the LCA online algorithm does.LCA Online Algorithm Description (examp

Topic: Given a length of 2^n arrangement, there are n operations, the first action is "to divide the sequence into 2^ (n-i+1) segments, each segment 2^ (i-1), and then choose Two-Segment Exchange", each operation at most once, to ask how many sequence of operations can be ordered out of the sequenceOrz DzyFirst, it is easy to see whether an operation sequence is legal and the sequence is irrelevant.So we just need to make sure that every action in an action sequence is chosen, so the contributio

MySQL replication, mysql master-slave Replication Replication refers to the upload of DDL and DML operations in the primary database to the replication server (also called slave server) through binary logs, and then re-Execute (also called redo) these logs on the server ), in this way, the data in the database of the s

MySQL Semi-synchronous Replication (Semi-synchronous Replication) in enterprise applications, MySQL often uses a master-slave architecture or a master-master architecture to achieve load balancing of MySQL servers, improves the performance of the MySQL server. the key is that MySQL Data Synchronization and replication can be implemented to provide a convenient me
