POSIX has scalability and efficiency limitations that can develop into more and more necessary in data-intensive purposes like deep studying, however till now it has retained one key benefit over the infinitely scalable object storage: the power to course of knowledge in reminiscence. That benefit is now gone with the brand new mmap_obj() perform, which paves the way in which for object storage to develop into the popular strategy to Massive Knowledge purposes.
POSIX options like statefulness, prescriptive metadata, and powerful consistency “develop into a efficiency bottleneck as I/O requests multiply and knowledge scale…” claims the article.
“The mmap_obj() builders observe that one piece of labor nonetheless must be carried out: there must be a munmap_obj() perform to launch knowledge from the person area, just like the POSIX perform.”
