Memory Allocation
A core mechanism of operating systems and runtime systems that refers to the scheduling process of dividing limited physical memory or virtual address space among different processes, threads, or data structures during program execution. Common strategies include contiguous allocation, paging, segmentation, and the buddy system.

Memory allocation is one of the core mechanisms of operating systems and runtime systems, referring to the scheduling process during program execution in which limited physical memory or virtual address space is partitioned among different processes, threads, or data structures.
The key challenge of memory allocation lies in the fact that total memory is fixed, while process requests are dynamic and unpredictable.
Rollback refers to the system's ability to restore a previously consistent state when an operation fails or the state becomes abnormal; in memory allocation, this manifests as releasing allocated pages and restoring swap space, with low cost and reversibility.
The model has no concept of questions like "how much memory should be allocated to the system" and can only answer them through production environment experiments.
Frequent or large memory allocations trigger garbage collection (GC), and in lightweight environments this overhead is amplified manifold.
