Cloud-based databases face increasing burdens, necessitating efficient memory management for improved performance and cost savings. Alibaba Cloud introduces Eigen+, a cluster management system allowing memory over-subscription without sacrificing reliability. Traditional methods struggle with high-load predictions, leading to operational risks such as OOM errors. Eigen+ uses machine learning for classification based on both runtime and non-runtime characteristics, enhancing predictability. It identifies transient instances to minimize risks associated with over-subscription, thus maintaining service level objectives while optimizing infrastructure usage through its hybrid scheduler.
Efficient memory management is crucial to achieving better performance and cost savings in cloud-based databases, especially as they become increasingly burdened.
Alibaba Cloud's Eigen+ enables memory over-subscription without compromising reliability or service quality by identifying transient instances that lead to OOM errors.
