Alibaba Cloud developed Eigen+, a new cluster management system that enhances memory allocation efficiency by 36% and prevents Out of Memory (OOM) errors in production database environments. The system addresses the challenge of maximizing memory utilization while adhering to Service Level Objectives. In MySQL clusters, Eigen+ improves the memory allocation ratio from 75.67% to 111.88% on average. The technology is deployed in thousands of database instances supporting both OLTP and OLAP workloads, translating to significant cost savings and improved reliability for organizations.
The new memory management system achieved a 36% improvement in memory allocation efficiency while eliminating Out of Memory (OOM) errors in production database environments.
Eigen+ improves the memory allocation ratio of an online MySQL cluster by 36.21% on average, while maintaining Service Level Objectives compliance with no OOM occurrences.
The technology supports both online transaction processing (OLTP) workloads using MySQL and online analytical processing (OLAP) workloads using AnalyticDB for PostgreSQL.
Significant cost savings and improved reliability can be achieved, allowing organizations to run more database instances on the same hardware while reducing the risk of outages.
