High Availability
Last updated: 2026-01-04 14:53:46
TDMQ for RabbitMQ provides multi-dimensional high-availability capabilities, such as cross-AZ deployment and data persistence, effectively enhancing the stability and disaster recovery capabilities of the message service.
Cluster-Level High Availability
Cluster Type | High-Availability Capability | Description |
Managed Edition | Cross-AZ deployment | When you purchase a TDMQ for RabbitMQ Managed Edition cluster in a region that has more than 2 availability zones (AZs), you can deploy the cluster across 2 to 3 AZs. This way, the nodes can be evenly distributed across these AZs. This deployment method ensures that the cluster remains operational even if a single AZ becomes unavailable. |
Serverless Edition | | Clusters are automatically deployed across multiple AZs at the underlying layer without requiring manual AZ selection. Cluster nodes are automatically distributed across these AZs, ensuring service continuity if a single AZ fails and providing IDC-level disaster recovery. |
Data High Availability
Cluster Type | High-Availability Capability | Description |
Managed Edition | Mirrored queue | Multi-node deployments support enabling mirrored queues, which can be configured for multi-replica synchronization. Mirrored queues can replicate messages across multiple nodes in a RabbitMQ cluster, ensuring that messages in the queue will not be lost if a node fails and maintaining service availability. |
Serverless Edition | Data persistence with a three-replica configuration | Clusters support data persistence with three replicas by default. Combining persistent storage with multi-node redundancy ensures that business data is protected from loss and service continuity is maintained in all scenarios. |
