Memgraph has introduced a High Availability Automatic Failover feature, designed to ensure continuous database availability and robust performance for applications moving into production environments. Available with the Enterprise license, this feature eliminates the need for manual coding by automatically detecting failures and rerouting traffic to maintain uninterrupted service. At the core of this system is the MAIN-REPLICA mechanism, where the MAIN instance handles write operations and multiple REPLICA instances handle read operations, ready to be promoted to MAIN if necessary. Synchronous and asynchronous replication modes offer flexibility, emphasizing either data consistency or availability. The system leverages the Raft consensus algorithm to prevent single points of failure, ensuring the cluster remains operational as long as the majority of servers can communicate. This high availability is crucial for applications like financial services and e-commerce platforms, where continuous data availability impacts business outcomes. Setup involves enabling high availability and configuring cluster nodes, with deployment options including environment variables and forthcoming support for Kubernetes. Monitoring and maintenance are managed by coordinators that check the health of instances and manage failovers to ensure system resilience.
