from that of the shallow copy. The deep copy creates a new object andIn the original object, the corresponding field is the same (the content is the same), that is, this reference is different from the original object reference, we changeThis field in the object does not affect the content of the corresponding field in the original object. Shallow copy: to implement shallow copy, you must use the memberwiseclone method of the object class to create a superficial copy.Deep

(1) shallow copy (shallow clone)All the variables of the Copied object contain the same value as the original object, and allStill point to the original object. In other words, the shortest replication only copies the object to be considered, instead of copying the objectThe referenced object. (2) Deep replication (deep cloning)All variables of the Copied object contain the same value as the original obje

MySQL master-slave replication:Lab Environment:Linux CentOS7 two: 192.168.230.10 (master)----192.168.230.11 (from) (System installed, switch off the firewall or configure the firewall).MySQL 5.7 (Download the official Yum source, yum install-y MySQL mysql-server)To start the configuration:MySQL configuration files in general Linux are all in/ETC/MY.CNF (the configuration file in Windows is Mysql.ini)server-ID1 (guaranteed unique in the entire MySQL cluster) log-bin = binlog (binary) log-bin-ind

Master the Binlog file through a line called dump path to Slave, slave will receive an event written to a file called Relay log (relay log), and then according to relay log with a call applier something to commit ( Write datafile, and Binlog)The Binlog and relay log content is not always the same, because you can set the eventsize if there is a thing on master that writes to the Binlog so that the size e

Label:4.5 Make stream replication more robustWhen connecting to master, the first thing slave to do is catch up with master. But is this going to work all the time? We've seen that we can use a mix of stream-based and file-based settings. This gives us some extra security to prevent the flow from not working.In real-world scenarios, the two methods of transmitting xlog may be overly complex. In many cases, using a stream is sufficient. The crux of the

Both replication and CDC use LogReader to read data changes from the log, and then write to the distribution library (copy) or the change table. 1> Create a replication publication individually In this case, the log Read Agent job is created at the Distributor (Servername_dbname_logreaderid) 2> uses the CDC alone In that case, two jobs ' CDC will be created on the agent of the current instance.

Replication of complex linked lists and replication of complex linked lists Question: there is a complex linked list. Besides a m_pNext pointer pointing to the next node, there is also a m_pSibling pointing to any node or NULL in the linked list. The node C ++ is defined as follows: 1 struct ComplexNode 2 3 { 4 5 int m_nValue; 6 7 ComplexNode* m_pNext; 8 9 ComplexNode* m_pSibling;10 11 }; C
