The most basic cluster mode for Mysql and MariaDB is the master-slave mode, which is also the most widely used cluster mode for many small and medium-sized enterprises. This cluster is easy to deploy and can be used. Let's step by step. The version used for the test is MariaDB10.1 source code installation, installed under the default path usrlocalmysql. $ BUILDautorun. sh $. configure $ make-j4 $ sudo The m

server and is composed of 128 random characters, the mysql-5.6 relies on the server-id and uuid to identify each host in the replication architecture, because 128-bit random strings are not repeated globally, server-id and uuid and the transaction serial number of every mysql transaction constitute a unique gtid, since the introduction of mysql-5.6, every binary log will write the gtid mark in the header of every transaction, therefore, gtid makes it easy to track and compare duplicate things a

only one SQL thread in the slave database to execute write operations. In the long run, the gap between the slave database and the master database will grow bigger and bigger. In this case, multiple SQL threads can be started from the slave database to execute write operations. Each thread is responsible for executing all related transactions of a database in the master database. In addition, after a trans

MariaDB's GTID replication and multi-source replication, mariadbgtid Replication What is GTID? GTID is the global transaction ID (global transaction identifier). It was initially implemented by google and officially added to MySQL in MySQL 5.6. GTID is actually composed of UUID + TID. UUID is the unique identifier of a MySQL instance. TID indicates the number of transactions committed on the instance, and increases monotonically as the transaction is

Label:What is Gtid? Gtid is the global transaction ID (transaction identifier), originally implemented by Google, and official MySQL joined the feature in 5.6. Gtid is actually made up of Uuid+tid. Where the UUID is the unique identity of a MySQL instance. The TID represents the number of transactions that have been committed on the instance and is monotonically incremented as the transaction commits. What is multi-source replication?
