The Challenge

A leading mortgage finance company based in Canada needed specialised support to ensure their RabbitMQ messaging system could reliably manage critical operations, including loan processing, customer communications, and transaction workflows. The company faced challenges such as frequent memory pressure on RabbitMQ nodes, inconsistencies in queue synchronisation, and the need for a more resilient architecture to handle peak processing loads.

Our Solution

Seventh State optimised memory management across the RabbitMQ clusters by fine-tuning the memory watermark settings, significantly reducing the risk of node crashes during periods of high demand. To enhance queue synchronization, we recommended transitioning from classic mirrored queues to quorum queues, improving data consistency and reducing failover times. Additionally, we helped scale the RabbitMQ architecture to better manage peak transaction volumes, ensuring reliable and efficient loan processing.

The Results

Enhanced System Stability

By optimising memory settings, we improved the stability of RabbitMQ clusters, significantly reducing node crashes and ensuring consistent performance during high-traffic periods.

Improved Data Consistency

Transitioned to quorum queues, which led to better synchronization and reliability, especially during node failovers and system restarts.

Scalable Architecture

Assisted in scaling the RabbitMQ infrastructure, enabling the company to handle increased transaction volumes without compromising performance or reliability


The Impact

Through our support, our client has significantly improved the performance and reliability of their RabbitMQ infrastructure. This ensures that their mortgage processing operations remain robust, capable of handling high volumes of transactions with greater efficiency and stability, ultimately supporting their mission to deliver top-tier financial services to their clients.
