In-memory big data analytics under space constraints using dynamic programming
تحلیل داده های بزرگ درون حافظه ای تحت محدودیت فضایی با استفاده از برنامه نویسی پویا-2018 The emergence of persistent memories has powered the data processing with the in-memory environ
ment and in-memory data analytics have become an advance of high-performance data processing. Re
cent explorations of using in-memory technologies address the improvement of the memory performance
from re-designing file systems. Most current approaches mitigate data exchanges between buffers and
disks by migrating workload to memories. However, this type of solutions will be encountering the
restriction of the memory size with the rapid growth of the application volume. This paper focuses
on the issue caused by the large amount of data processing within in-memory systems and proposes
a novel approach that is designed to dynamically determine whether the data processing should be
accomplished in the memory. The proposed approach is called Smart In-Memory Data Analytics Manager
(SIM-DAM) model, which utilizes a dynamic working manner of the file system, as well as fully uses
hardware mappings. The experimental results obtained from our laboratory evaluations represent that
the throughputs of SIM-DAM can achieve a high-level performance with different input data sizes without
the constraints of the memories’ spaces.
