Managing "Big Data" for Astronomical Data Analysis.

天文学正在经历一场规模革命；当前的数据库只有10tb大小，而下一代调查将产生多pb的数据。这些庞大的数据集提供了令人兴奋的机会，使迄今为止不可能的统计分析成为可能，但只有在能够应对一系列数据管理挑战的情况下，它们的潜力才能实现。服务于1-10TB规模的工具将无法扩展到这些更大的容量。在本项目中，我们将评估行业领先的大数据技术及其支持天文数据分析的适用性。

Astronomy is undergoing a revolution in scale; current databases are a few 10's of TB in size whereas the coming generation of surveys will yield multi-PB of data. These vast datasets provide exciting opportunities, enabling statistical analysis that have been hitherto impossible, but their potential can only be realised if a range of data management challenges can be met. The tools that have served the 1-10TB scale regime will not scale to these larger volumes. During this project we shall assess industry leading big data technologies and their suitability to supporting astronomical data analysis.
