So far, we have processed file-based replication (or log shipping) and simple stream-based replication settings. In both cases, after the transaction is committed on master, the data is submitted and received by slave. It will still be lost at the time that master commits and slave actually receives the data completely.In this chapter, we will study the following topics:• Ensure that no transactions are los

One, Introduction
In today's rapidly changing business age, business decisions must be made and acted upon in the first place to stay ahead of the competition. If business data is not guaranteed to be synchronized, then production and profits are bound to suffer, but it is not eas
IntroducedOne important feature of Meta compared to Kafka is the implementation of the message high availability scenario, which we call the HA scenario. The message is written to the disk immediately after it is sent to the broker and returned to the client to tell the producer that the message was sent successfully, and the control of the unflushThreshold unflushInterval two parameters can guarantee the security of the stand-alone message data, as long as the machine's disk is not permanently

The dump process in the master node reads binary files and has the replication client and replication slave permissions on the slave server's I/O threads.Read the binary file of the master server and record it to relay-log.

About MySQLMySQL is a relational database management system, where relational databases store data in different tables rather than putting all of the data in a large warehouse, which increases speed and increases flexibility.The SQL language used by MySQL is the most commonly used
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. Dbname_captu

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
