The Family of MapReduce and Large Scale Data Processing Systems

In the last two decades, the continuous increase of computational power has produced an overwhelming flow of data which has called for a paradigm shift in the computing architecture and large scale data processing mechanisms. MapReduce is a simple and powerful programming model that enables easy development of scalable parallel applications to process vast amounts of data on large clusters of commodity machines. It isolates the application from the details of running a distributed program such as issues on data distribution, scheduling and fault tolerance. However, the original implementation of the MapReduce framework had some limitations that have been tackled by many research efforts in several followup works after its introduction. This article provides a comprehensive survey for a family of approaches and mechanisms of large scale data processing mechanisms that have been implemented based on the original idea of the MapReduce framework and are currently gaining a lot of momentum in both research and industrial communities. We also cover a set of introduced systems that have been implemented to provide declarative programming interfaces on top of the MapReduce framework. In addition, we review several large scale data processing systems that resemble some of the ideas of the MapReduce framework for different purposes and application scenarios. Finally, we discuss some of the future research directions for implementing the next generation of MapReduce-like solutions.Comment: arXiv admin note: text overlap with arXiv:1105.4252 by other author

Splenomegaly and Tumor Marker Response Following Selective Internal Radiation Therapy for Non-Resectable Liver Metastases from Neuroendocrine Tumor

PURPOSE:The aim of this study was to investigate changes in spleen size, the level of chromogranin Aas a tumor marker, and the relationship between these two parameters before and 3 months after selectiveinternal radiation therapy (SIRT) for non-resectable liver metastases from neuroendocrine tumor (NET).Our first serious adverse event with this relatively new treatment is also discussed.METHODS:A retrospective review of a prospective database identified patients with non-resectable livermetastases from NET who underwent SIRT between 2003 and 2007. Patients who underwent CT scansbefore and 3 months after treatment were included. The patients were divided into two groups:those withand without a 20 % or more increase in splenic volume on the CT scans. The percentages of patients showinga tumor marker response in the two groups were then comparedRESULTS:Fourteen patients were included in the present analysis. A tumor marker response was seenin 6 of 7 patients( 85.7%) who showed an increase in splenic volume of>20%, and in 3 of 7 patients( 42.9%) without an increase in splenic volume (p=0.266). There was one death as a result of oesophageal varicealbleeding due to portal hypertension at 9 months after treatment.CONCLUSION:Splenic enlargement after SIRT may be associated with tumor marker response, althoughthis could not be confirmed statistically in this study due to the small number of patients. Long-termsplenomegaly and portal hypertension may be important complications of SIRT. This issue needs to be investigatedfurther using a larger number of patients and longer follow-up
