InfluxDB Essentials
"InfluxDB Essentials" InfluxDB Essentials is a comprehensive guide for anyone seeking to harness the full potential of InfluxDB, the industry-leading time series database. The book begins by establishing a robust foundation in the principles of time series data, exploring its unique properties, architectural considerations, and the comparative strengths of InfluxDB versus other popular time series databases. Practical industry use cases in IoT, observability, finance, and scientific monitoring are presented, along with an insightful discussion on the challenges of large-scale time series storage and emerging trends in data management. Delving deep into the architecture and operational mechanics of InfluxDB, this book offers readers clear, practical guidance on schema design, performance tuning, and high-availability deployments—covering everything from core components such as the storage engine and write-ahead log to strategies for data ingestion, retention, clustering, and security. Advanced chapters navigate through data integration pipelines, optimal ingestion approaches, precise time synchronization, and real-world strategies for handling late, duplicate, or out-of-order data. Readers will also benefit from extensive coverage of advanced querying and analytics capabilities, performance and reliability optimization, rigorous backup and disaster recovery methodologies, and sophisticated security and compliance strategies. The book concludes by showcasing ecosystem integrations, observability enablers, and the future trajectory of InfluxDB in cutting-edge applications like serverless computing, edge analytics, machine learning, and global-scale deployments. Whether you are a developer, data engineer, or architect, InfluxDB Essentials is your indispensable companion for building scalable, secure, and intelligent time series data solutions.

Workshops at 18th International Conference on Intelligent Environments (IE2022)
The term Intelligent Environments (IEs) refers to physical spaces in which information and communication technologies are interwoven with sensing technologies, innovative user interfaces, robotics and artificial intelligence to create interactive spaces which increase the awareness and enhance the experience of those occupying them. The growing IE community is rooted in academia, but increasingly involves practitioners. It explores the core ideas of IEs as well as the factors necessary to make them a reality, such as energy efficiency, the computational constraints of edge devices and privacy issues. This book presents papers from Workshops held during the 18th International Conference on Intelligent Environments, IE2022, held as a hybrid conference in Biarritz, France, from 20 to 23 June 2022. The conference is now recognized as a major annual venue in the field of IE. It offers a truly international forum for the exchange of information and ideas, and welcomes contributions from all technically active regions of the planet. Included here are 35 papers from the 1st International Workshop on Sentiment Analysis and Emotion Recognition for Social Robots (SENTIRobots’22); 1st International Workshop on Edge AI for Smart Agriculture (EAISA’22); 2nd International Workshop on Artificial Intelligence and Machine Learning for Emerging Topics (ALLEGET’22); 11th International Workshop on the Reliability of Intelligent Environments (WoRIE’22); 2nd International Workshop on Self-Learning in Intelligent Environments (SeLIE’22); 5th Workshop on Citizen Centric Smart Cities Solutions (CCSCS’22); 11th International Workshop on Intelligent Environments Supporting Healthcare and Well-being (WISHWell’22) Exploring some of the latest research and developments in the field, the book will be of interest to all those working with intelligent environments and its associated technologies.
