The Challenge

An American financial services organisation providing technology infrastructure to fintech required specialised support to maintain the efficiency and reliability of their RabbitMQ messaging system, which is essential for processing high volumes of financial transactions, managing real-time data streams, and ensuring seamless communication between distributed services. The company faced challenges including cluster slowness caused by overloaded applications, memory management issues that risked potential outages, and the need for optimised Quorum Queue management to ensure data consistency across their infrastructure.

Our Solution

We implemented strategies to alleviate the impact of overloaded applications by adjusting memory watermark settings and optimising the use of SWAP files. To ensure the stability of the RabbitMQ clusters, we recommended reducing the ha-sync-batch-size and memory watermark values to prevent crashes during peak loads. Additionally, we offered guidance on the management of Quorum Queues, including manual replication processes and best practices for maintaining consistency during node changes.

The Results

Improved Cluster Performance

We optimised memory management and cluster settings to reduce the risk of crashes, enhancing the system’s ability to handle high transaction volumes without performance degradation.

Enhanced Quorum Queue Management

We provided clear strategies for managing Quorum Queues, ensuring that data remained consistent across the cluster, even during node maintenance or network disruptions.

Reduced Application Impact

Implemented solutions to mitigate the impact of overloaded applications on the cluster, including tuning memory settings and leveraging SWAP files to manage unexpected spikes in resource usage.


The Impact

With our help these improvement have ensured that our client’s fintech platform remains robust and responsive, capable of handling the demands of real-time financial services while maintaining high levels of data integrity and service continuity.
