Master-slave replication is an old topic. I will not talk about the details of master-slave replication here. I will focus on the differences between the logs and locations in show slave status \ G; First, cut a graph to facilitate the explanation: As shown in the figure, the more important parameter is * log and * pos. How can we differentiate them and what do they mean? Let's first talk about the principle of master-slave replication: I. Master-s

is to combine the results of two and or (add two product). Do you think the probability of the operation here? Independent event of God Horse. Yes, it has a close connection! Because the binary number operation itself is a probability operation. For example, there are 8 empty bits, then we have 8 positions to put 0 and 1, then the total probability is 2^8=256, that is, there are 256 ways to put, this is not the range of 8bits (0~255). So the binary operation conforms to the probability calculat

Some rooms have three operations: one is continuous room occupancy, and the other is continuous room vacancy, the third is to ask how long the longest consecutive room is.Idea: it is obviously the question of the Line Segment tree. lazy thought is used in the middle. A difficult question, which requires careful consideration. The key to this question is that after lazy is used to update down, the information of the parent node needs to be changed based on the information of the child node. That
