This paper quantifies the scalability of a document store named MongoDB and an extensible store named HBase for processing simple operations using a social networking benchmark named BG (www.bgbenchmark.org). We report on the vertical and the horizontal scalability of both data stores. We quantify speedup and scaleup characteristics of each data store's Social Action Rating (SoAR). SoAR is the highest...
With a wide variety of big data applications, the past few years have witnessed an increasing number of data stores with novel design decisions that may sacrifice the correctness of an application's operations to enhance performance. This paper presents our work-in-progress on a framework that generates a validation component. The input to the framework is the characteristics of an application. Its...
A SOcial LIve Stream, SOLIS, is a live stream produced by a device whose owner is sharing the stream with her friends, granting each friend to perform time shifted viewing for a pre-specified duration. The system buffers this chase data to facilitate its browsing and display. In the presence of many Solis, memory may overflow and prevent display of some chase data. This paper presents a novel data-aware...
