Previous issue date: 2018-11-12Performance of big data systems largely relies on efficient data reconfiguration techniques. Data reconfiguration operations deal with changing configuration parameters that affect data layout in a system. They could be user-initiated like changing shard key, block size in NoSQL databases, or system-initiated like changing replication in distributed interactive analytics engine. Current data reconfiguration schemes are heuristics at best and often do not scale well as data volume grows. As a result, system performance suffers.
In this thesis, we show that {\it data reconfiguration mechanisms can be done in the background by using new optimal or near-optimal algorithms coupling them with performant system designs}. We explore four different data reconfiguration operations affecting three popular types of systems -- storage, real-time analytics and batch analytics. In NoSQL databases (storage), we explore new strategies for changing table-level configuration and for compaction as they improve read/write latencies. In distributed interactive analytics engines, a good replication algorithm can save costs by judiciously using memory that is sufficient to provide the highest throughput and low latency for queries. Finally, in batch processing systems, we explore prefetching and caching strategies that can improve the number of production jobs meeting their SLOs. All these operations happen in the background without affecting the fast path.
Our contributions in each of the problems are two-fold -- 1) we model the problem and design algorithms inspired from well-known theoretical abstractions, 2) we design and build a system on top of popular open source systems used in companies today. Finally, using real-life workloads, we evaluate the efficacy of our solutions. Morphus and Parqua provide several 9s of availability while changing table level configuration parameters in databases. By halving memory usage in distributed interactive analytics engine, Getafix reduces cost of deploying the system by 10 million dollars annually and improves query throughput. We are the first to model the problem of compaction and provide formal bounds on their runtime. Finally, NetCachier helps 30\% more production jobs to meet their SLOs compared to existing state-of-the-art.Submission original under an indefinite embargo labeled 'Open Access'.

First person – Arijita Ghosh
No full textABSTRACT
First Person is a series of interviews with the first authors of a selection of papers published in Journal of Cell Science, helping early-career researchers promote themselves alongside their papers. Arijita Ghosh is the first author on “Leucine-rich repeat-containing 8B protein is associated with the endoplasmic reticulum Ca2+ leak in HEK293 cells”, published in Journal of Cell Science. Arijita is a PhD student in the laboratory of Amal Kanti Bera at the Indian Institute of Technology Madras, Chennai, India, investigating the role of leucine-rich repeat-containing 8 proteins in cellular calcium homeostasis.</jats:p
Copula regression and robustness
No full textThis thesis aims to study the application of copula-based regression method and its robustness. In the first chapter, we will briefly review the fundamentals of copula theory with some important results. For the second chapter, we will combine some copula selection criteria and then simulate data sets from different kinds of copulas and apply the copula-based regression method on these data sets and demonstrate why it performs better than the non-parametric regression method.
Subsequently, the third chapter will be the application on a real data set. Moreover, we will check the model's adequacy using another result from the goodness of fit for the copula models and apply the copula-based regression method to build a confidence interval of the prediction values. Finally, we will analyze and draw conclusion from these results and make some further research suggestions.Embargo status: Restricted until August 2023.

Beyond national literatures: Empire and Amitav Ghosh
No full textScholarship on the writer Amitav Ghosh has addressed issues of nationalism, postcolonial identity, ecocriticism, testimony, subalternity, and historiography. But the idea of Ghosh as an Asian American author with a particular relationship to the United States and its national mythologies, has barely been considered. In this essay, I explore this neglected aspect of Ghosh’s œuvre by looking at the idea of America in his writing and by situating his work within what I term "the Bengali American grain". Reading his work alongside that of other Bengali American writers and arguing that it is more ambitious thematically and more anti-imperialistic, I probe Ghosh’s problematic relationship with the United States, asking how his hemispheric writing continues to extend and even alter the terrain often associated with Asian American literature

Ep. #040 - Amitav Ghosh
No full textThis recording and transcript form part of a collection of podcasts conducted by the Cultures of Energy at Rice University. Cultures of Energy brings writers, artists and scholars together to talk, think and feel their way into the Anthropocene. We cover serious issues like climate change, species extinction and energy transition. But we also try to confront seemingly huge and insurmountable problems with insight, creativity and laughter.Cymene and Dominic define (finally!) professionalism and offer a brief review of Leonardo DiCaprio’s soon to be released climate change documentary, Before the Flood. Then (11:43) we are very pleased to welcome to the podcast acclaimed novelist, Amitav Ghosh, author of The Shadow Lines (1988), The Hungry Tide (2004) and The Ibis trilogy (2008-2015), among many other works. We talk about his latest work of non-fiction, The Great Derangement: Climate Change and the Unthinkable (University of Chicago Press, 2016) and why he thinks it has proven so difficult to bring climate change into literature. We discuss the worldview of the novel and how its emphasis on creating believable narratives has excluded precisely the kinds of unlikely anthropocenic encounters that are becoming increasingly frequent across the world. Amitav argues that before an alternate world can become a reality, it needs to become an imaginative reality and this is why the arts are so crucial to coming to terms with the Anthropocene. We also discuss “serious” art’s fear of being deemed merely “illustrative” and how this may be linked to a Cold War aversion to the aesthetics of socialist realism. Now, Amitav warns, the world has risen up as a protagonist even as our means of representation aren’t up to engaging it. He predicts that the mansions of serious fiction will suffer a similar fate to the mansions of Miami beach as our waters rise. We talk about what is really being denied in climate change denial and how the privileges and comforts of a carbon-fueled lifestyle is something which neither the West nor Asia is prepared to give up. We close with Amitav’s own next novel project and how climate change inspires him personally and artistically
