Global MySQL
Fault Tolerance

Fault Tolerance with Composite Active/Active Topology

In a Composite Active/Active (CAA) topology, writes are routed to the Primary MySQL node in the local Active cluster, if available, and to another Active cluster in a different region if the local cluster is unavailable.

A CAA Topology Contains

Minimum Configuration

2 clusters with 3-node (or 2-node + witness) per cluster.

Active/Active Design

All clusters are writeable, with changes replicated across all sites.

Global Data Synchronization

Ensures data consistency across geographically distributed clusters.

Cross-Site Replication

Managed replication flows in all directions.

Multi-Site Aware Connectors

Automatically redirect traffic to other clusters during failover.

Use Cases

3-Node Cluster

Geographic Distribution and Scaling for a Payment Gateway
Need

A payment gateway processes transactions for merchants across multiple regions and requires a database solution that supports real-time data synchronization. They need low-latency updates and continuous availability to ensure smooth operations.

Solution

The payment gateway deploys Tungsten CAA (3-Node) to enable real-time data synchronization across distributed sites. Each cluster operates as a writeable primary, ensuring low-latency updates and uninterrupted transaction processing. The solution provides seamless failover and global data consistency, supporting the gateway’s worldwide operations.

2 Node + Witness Cluster

Simplified Active/Active for SaaS
Need

A SaaS provider offering a collaboration platform needs an Active/Active solution to ensure high availability but wants to avoid the complexity and cost of a full-scale setup.

Solution

The SaaS provider deploys Tungsten CAA (2-node +) to simplify Active/Active operations. Writes are directed to a preferred primary node, while reads are routed locally. The lightweight witness ensures failover quorum, delivering a cost-effective solution for continuous availability and low-latency performance.
