The system has been deployed in Alibaba Cloud’s production environment. The research paper claimed that in online MySQL clusters, Eigen+ “improves the memory allocation ratio of an online MySQL cluster by 36.21% (from 75.67% to 111.88%) on average, while maintaining SLO compliance with no OOM occurrences.”
For enterprise IT leaders, these numbers can translate into significant cost savings and improved reliability. The 36% improvement in memory allocation means organizations can run more database instances on the same hardware while actually reducing the risk of outages.
Alibaba Cloud’s Eigen+ has a classification-based memory management approach, whereas peers, AWS, Microsoft Azure, and Google Cloud, primarily rely on prediction-based memory management strategies, which, while effective, may not fully prevent OOM occurrences, explained Kaustubh K, practice director, Everest Group. “This difference in approach can position Alibaba Cloud’s Eigen+ with a greater technical differentiation in the cloud database market, potentially influencing future strategies of other hyperscalers.”
