Abstract: A database memory manager determines a size class for each of a plurality of memory allocation requests. The memory manager then, based on the determined size classes, assigns which of a plurality of sub-allocators forming part of a plurality of memory pools should handle each memory allocation request. The sub-allocators assignments are based on predefined size ranges for each size class. The corresponding assigned sub-allocators then identify locations within the memory for each memory allocation request. The corresponding assigned sub-allocators next handle the memory allocation requests to allocate memory at the identified locations such that one of the sub-allocators utilizes both thread local storage and core-striped memory management.
