Changing InnoDB Cluster Topology in MySQL By default, an InnoDB Cluster runs in single-primary mode, where the cluster has one primary server that accepts read and writes queries (R/W), and all of the remaining instances in the cluster accept only read queries (R/O). When you configure a cluster to run in multi-primary mode, all of
How to Setup MySql InnoDB Cluster MySQL InnoDB Cluster provides a complete high availability solution for MySQL. By using the AdminAPI included with MySql Shell, you can easily configure and administer a group of at least three MySQL server instances to function as an InnoDB Cluster. Each MySQL server instance runs MySQL Group Replication, which
Adopting a Group Replication Deployment into InnoDB Cluster in MySQL If you have an existing deployment of Group Replication and you want to use it to create a cluster, pass the adoptFromGR option to the dba.createCluster() function. The created InnoDB Cluster matches whether the replication group is running as single-primary or multi-primary. To adopt
How to change Group Replication Mode in MySQL In this blog, we will see How to change the mode in which a group is running in, either single or multi-primary. For this we will use two functions group_replication_switch_to_multi_primary_mode() & group_replication_switch_to_single_primary_mode(). These functions used to change a group’s mode can be run on any member. In
Deploying MySql Group Replication in Single-Primary Mode Group Replication is provided as a plugin to MySQL Server. MySQL Group Replication enables you to create elastic, highly-available, fault-tolerant replication topologies and Group Replication guarantees that the database service is continuously available. Groups can operate in a single-primary mode with the automatic primary election, where only one

We will use the same configuration to install and bootstrap mysql router. Bootstrap MySQL Router against an InnoDB ReplicaSet
How to perform Switchover/Failover in MySql InnoDB ReplicaSet In the previous blog, we saw Part I: How to Configure InnoDB ReplicaSet MySQL Click here to read more. We will use the same configuration to perform Switchover & Failover in InnoDB ReplicaSet. Below are the setup information. Hostname IP Role Server_ID Port Installation Link test-machine01 192.168.114.177
How to Configure InnoDB ReplicaSet mysqlshell AdminAPI includes support for InnoDB ReplicaSet, which enables you to create and administer a set of MySQL instances running asynchronous GTID-based replication. An InnoDB ReplicaSet consists of a single primary and multiple replicas. InnoDB ReplicaSet Prerequisites Only instances running MySQL version 8.0 and later are supported. Only GTID-based replication is supported, binary log file
Asynchronous Replication Automatic Failover in MySQL MySQL 8.0.22 supports an asynchronous connection failover mechanism. This feature allows a replica/slave to automatically failover to a new source/master, in case its existing source/master fails. When the existing connection source/master fails, the replica first retries the same connection for the number of times specified by the MASTER_RETRY_COUNT. The
How to Setup MySQL Master-Master Replication (Circular Replication) Master-Master Replication (Circular Replication) also known as ring topology in MySQL, this setup requires two or more MySQL servers which act as a master. All masters receive writes and generate binlogs. Below points should be considered while doing the master-master setup. You need to set an auto-increment
