Enhancing MySQL Cluster Uptime: Advanced Detection, Mitigation, and Consensus with Group Replication

Primary Promotion is one of the most critical operations being performed in MySQL Clusters. In this presentation, we will look at different techniques we employed in optimizing the primary failover time. We will also look at the deployment model of MySQL Group Replication in the clusters around how we efficiently deploy to withstand outages like failure of an entire zone. We will look at the following topics in detail. Faster Primary Failovers - Detection, Group Replication Deployment and Operations Increased Reliability - Tolerance for AZ failure and not compromising latency. Data Integrity - Mitigating Errant GTID issues. Different Consistency Guarantees. Operational Efficiency.
