Citus for Scalable PostgreSQL Systems
"Citus for Scalable PostgreSQL Systems" "Citus for Scalable PostgreSQL Systems" is a comprehensive guide designed for engineers, architects, and database administrators seeking to master the art of scaling PostgreSQL beyond single-node limitations. This book opens with a meticulous exploration of PostgreSQL’s foundational architecture, highlighting inherent challenges in scaling traditional relational databases, and then sets the stage by introducing the principles and evolution of Citus as a distributed extension. Readers will gain clarity on distributed data models, the shared-nothing approach, and strategic considerations for when— and when not—to leverage Citus in modern deployments. Delving deep into Citus internals, the book unpacks essential architectural elements such as coordinator and worker nodes, sharding mechanisms, and efficient data distribution strategies. It offers actionable guidance on end-to-end deployment: from on-premise to cloud-native and managed cluster setups, complete with best practices for security, networking, provisioning, and advanced container orchestration. For practitioners tackling demanding workloads, detailed chapters on schema design, distributed query execution, real-time data ingestion, and analytical processing illuminate the nuances of high-performance, large-scale PostgreSQL systems powered by Citus. Further, the narrative extends to address the operational lifecycle: high availability, fault tolerance, and day-two operations, including shard rebalancing, maintenance, and cost optimization. Security and compliance are covered exhaustively, with recommendations for access controls, auditing, and tenant isolation. Shaped by real-world case studies and emerging trends, "Citus for Scalable PostgreSQL Systems" is both a technical playbook and an industry roadmap, empowering data professionals to build resilient, elastic, and future-proof PostgreSQL clusters.
Learn PostgreSQL
A comprehensive guide to building, managing, and securing scalable and reliable database and data warehousing applications using Postgres 12 and 13 Key FeaturesSet up your database cluster and monitor, secure, and fine-tune it for optimal performanceLearn the fundamentals of database management and implement client- and server-side programming using SQL and PL/pgSQLExplore useful tips to develop efficient PostgreSQL database solutions from scratchBook Description PostgreSQL is one of the fastest-growing open source object-relational database management systems (DBMS) in the world. As well as being easy to use, it’s scalable and highly efficient. In this book, you’ll explore PostgreSQL 12 and 13 and learn how to build database solutions using it. Complete with hands-on tutorials, this guide will teach you how to achieve the right database design required for a reliable environment. You'll learn how to install and configure a PostgreSQL server and even manage users and connections. The book then progresses to key concepts of relational databases, before taking you through the Data Definition Language (DDL) and commonly used DDL commands. To build on your skills, you’ll understand how to interact with the live cluster, create database objects, and use tools to connect to the live cluster. You’ll then get to grips with creating tables, building indexes, and designing your database schema. Later, you'll explore the Data Manipulation Language (DML) and server-side programming capabilities of PostgreSQL using PL/pgSQL, before learning how to monitor, test, and troubleshoot your database application to ensure high-performance and reliability. By the end of this book, you'll be well-versed with the Postgres database and be able to set up your own PostgreSQL instance and use it to build robust solutions. What you will learnUnderstand how users and connections are managed by running a PostgreSQL instanceInteract with transaction boundaries using server-side programmingIdentify bottlenecks to maintain your database efficientlyCreate and manage extensions to add new functionalities to your clusterChoose the best index type for each situationUse online tools to set up a memory configuration that will suit most databasesExplore how Postgres can be used in multi-instance environments to provide high-availability, redundancy, and scalabilityWho this book is for This Postgres book is for anyone interested in learning about the PostgreSQL database from scratch. Anyone looking to build robust data warehousing applications and scale the database for high-availability and performance using the latest features of PostgreSQL will also find this book useful. Although prior knowledge of PostgreSQL is not required, familiarity with databases is expected.
PostgreSQL Foundations
"PostgreSQL Foundations" "PostgreSQL Foundations" is an authoritative guide for database professionals, architects, and developers seeking a comprehensive and practical understanding of PostgreSQL. This expertly structured book delves deeply into the heart of the PostgreSQL ecosystem, starting with its internal architecture, memory management, storage organization, and the principles that underpin its durability and transactional integrity. Readers are led from first principles to advanced internal mechanisms such as multi-version concurrency control (MVCC), extensibility, and system catalogs, providing both the theoretical context and the pragmatic insights required to fully leverage PostgreSQL’s powerful design. Spanning every aspect of PostgreSQL administration, the book thoroughly covers installation and configuration across diverse platforms, best practices for security and authentication, and strategies for logging, monitoring, routine maintenance, and seamless version upgrades. Advanced chapters focus on sophisticated data modeling, partitioning strategies, and indexing, as well as SQL mastery, procedural programming, and external integration—empowering readers to design robust schemas and write efficient, maintainable queries. Practical guidance on backup, replication, disaster recovery, high availability architectures, as well as scaling vertically and horizontally, equip practitioners to build and sustain resilient, high-performance environments. The final chapters place PostgreSQL in the wider context of the modern data ecosystem, with in-depth coverage of cloud-native deployments, DevOps integration, microservices, observability, and community-driven extensions. With an eye to the future, the book concludes with emerging trends and a forward-looking roadmap, making it not only an essential reference for today’s data challenges but also a guide for tomorrow’s opportunities. Whether building your first production system or optimizing a global data platform, "PostgreSQL Foundations" offers the definitive foundation for mastering one of the world’s most advanced open source databases.
