摘要

虽然研究人员可以利用 Apache Spark 大规模执行科学工作流，但由于框架设计的局限性，他们往往缺乏出处支持。本文介绍了 Apache Spark 的出处扩展 SAMbA-RaP。其重点在于(i) 在工作流中执行具有密集 I/O 操作的外部黑盒应用程序，同时利用 Spark 的内存数据结构；(ii) 从内存数据结构中提取特定领域的数据；(iii) 在工作流执行中实施数据版本管理并捕获出处图。SAMbA-RaP 还通过网络接口提供实时报告，使科学家能够在运行工作流时探索数据流转换和内容演变。

Version [1.0]- [SAMbA-RaP is music to scientists’ ears: Adding provenance support to spark-based scientific workflows]

While researchers benefit from Apache Spark for executing scientific workflows at scale, they often lack provenance support due to the framework’s design limitations. This paper presents SAMbA-RaP, a provenance extension for Apache Spark. It focuses on: (i) Executing external, black-box applications with intensive I/O operations within the workflow while leveraging Spark’s in-memory data structures, (ii) Extracting domain-specific data from in-memory data structures and (iii) Implementing data versioning and capturing the provenance graph in a workflow execution. SAMbA-RaP also provides real-time reports via a web interface, enabling scientists to explore dataflow transformations and content evolution as they run workflows.

期刊介绍： SoftwareX aims to acknowledge the impact of software on today''s research practice, and on new scientific discoveries in almost all research domains. SoftwareX also aims to stress the importance of the software developers who are, in part, responsible for this impact. To this end, SoftwareX aims to support publication of research software in such a way that: The software is given a stamp of scientific relevance, and provided with a peer-reviewed recognition of scientific impact; The software developers are given the credits they deserve; The software is citable, allowing traditional metrics of scientific excellence to apply; The academic career paths of software developers are supported rather than hindered; The software is publicly available for inspection, validation, and re-use. Above all, SoftwareX aims to inform researchers about software applications, tools and libraries with a (proven) potential to impact the process of scientific discovery in various domains. The journal is multidisciplinary and accepts submissions from within and across subject domains such as those represented within the broad thematic areas below: Mathematical and Physical Sciences; Environmental Sciences; Medical and Biological Sciences; Humanities, Arts and Social Sciences. Originating from these broad thematic areas, the journal also welcomes submissions of software that works in cross cutting thematic areas, such as citizen science, cybersecurity, digital economy, energy, global resource stewardship, health and wellbeing, etcetera. SoftwareX specifically aims to accept submissions representing domain-independent software that may impact more than one research domain.
