The Presto community has mushroomed since its origins at Facebook in 2012. But ramping up this distributed SQL query engine can be challenging even for the most experienced engineers. This practical book shows you how to begin Presto operations at your organization to derive insights on datasets wherever they reside. Authors Angelica Lo Duca, Vivek Bharathan, and George Wang explain what Presto is, where it came from, and how it differs from other data warehousing solutions. You'll discover why Facebook, Uber, Twitter, and cloud providers, including AWS, Google Cloud, and Alibaba, use Presto and how you can quickly deploy Presto in production. You'll learn about: Presto security and administration Syntax and connectors Clusters and tuning Troubleshooting: logs, error messages, and more Extending Presto for real-time business insight Extending PrestoDB

Comprehensive summary of Chalcogenide Nanophotonics, reviewing basic principles, synthesis methods, and cutting-edge applications Chalcogenide Nanophotonics offers an in-depth exploration of these remarkable materials, covering their fundamental physics, synthesis methods, optical phenomena, and cutting-edge applications in modern photonics. A distinctive feature of this book is its interdisciplinary approach, weaving together materials science, condensed matter physics, and photonic engineering. Each chapter integrates theoretical frameworks with practical case studies — such as phase-change memory devices leveraging GeSbTe alloys or GST-based metasurfaces for dynamic color displays — to illustrate the symbiotic relationship between material design and device performance. The inclusion of recent breakthroughs, such as van der Waals epitaxy for low-defect heterostructures and UV lithography for scalable metasurfaces, ensures relevance to both academic and industrial audiences. Chalcogenide Nanophotonics includes information on: Electronic band structure and material properties, elucidating how chemical bonding and lattice dynamics govern their optoelectronic behaviorIntricate mechanisms of thin-film growth, offering insights into epitaxial techniques such as chemical vapor deposition and pulsed laser depositionProperties of chalcogenides, covering dielectric functions, Raman spectroscopy, and emission mechanismsChalcogenide-based photonic crystals and metamaterials, showcasing their potential for beam steering, perfect absorption, and chiral light manipulationFuture challenges and opportunities, from machine learning-driven material discovery to monolithic 3D integration for quantum photonicsChalcogenide Nanophotonics serves as both a roadmap and an invitation to researchers, engineers, and students alike, encouraging them to harness the infinite potential of chalcogenides.
