Mountpoint for Amazon S3 introduced memory usage limitation capabilities that allow users to define fixed memory targets or rely on automatic detection based on running environments such as Amazon EKS containers. Under memory pressure, Mountpoint modulates its operations to stay within these limits, preventing performance degradation or conflicts with other software.
Previously, uncontrolled memory expansion could lead to stability issues. This update enables Mountpoint to function alongside memory-intensive applications including machine learning or analytics workloads without exceeding container or host memory budgets. The enhancement is available in all AWS Regions.
