Abstract
MySQL Group Replication is a solution that implements a fault-tolerant database system in which redundant components can be removed automatically without compromising the overall system's availability. The Asynchronous Replication Connection Failover feature complements this by further increasing the resilience of replication connections between a replica and a set of sources. It allows asynchronous replicas to switch to a new replication source when the current connection fails. Therefore, an asynchronous replica can automatically switch-over its replication connection to a new member, when it is replicating from a Group Replication group, for instance. In this session we will present how Asynchronous Replication Connection Failover feature automates the process of re-establishing a replication connection to another source, upon failure of the current one. We will also present about how this feature integrates with Group Replication and thus how setting it up can be automated as well. Come and learn more about this new and exciting replication feature in MySQL, directly from the engineers developing the product.
