دانلود کتاب PostgreSQL 10 High Performance: Expert techniques for query optimization, high availability, and efficient database maintenance

Leverage the power of PostgreSQL 10 to design, administer and maintain a high-performance database solutionKey FeaturesObtain optimal PostgreSQL 10 database performance, ranging from initial design to routine maintenance Fine tune the performance of your queries and avoid the common pitfalls that can slow your system down Contains tips and tricks on scaling successful database installations, and ensuring a highly available PostgreSQL solutionBook DescriptionPostgreSQL database servers have a common set of problems that they encounter as their usage gets heavier and requirements get more demanding. Peek into the future of your PostgreSQL 10 database's problems today. Know the warning signs to look for and how to avoid the most common issues before they even happen.Surprisingly, most PostgreSQL database applications evolve in the same way-choose the right hardware, tune the operating system and server memory use, optimize queries against the database and CPUs with the right indexes, and monitor every layer, from hardware to queries, using tools from inside and outside PostgreSQL. Also, using monitoring insight, PostgreSQL database applications continuously rework the design and configuration. On reaching the limits of a single server, they break things up; connection pooling, caching, partitioning, replication, and parallel queries can all help handle increasing database workloads.By the end of this book, you will have all the knowledge you need to design, run, and manage your PostgreSQL solution while ensuring high performance and high availabilityWhat you will learnLearn best practices for scaling PostgreSQL 10 installationsDiscover the best hardware for developing high-performance PostgreSQL applicationsBenchmark your whole system – from hardware to applicationLearn by real examples how server parameters impact performanceDiscover PostgreSQL 10 features for partitioning and parallel queryMonitor your server, both inside and outside the databaseDesign and implement a good replication system on PostgreSQL 10Who This Book Is ForThis book is designed for database administrators and PostgreSQL architects who already use or plan to exploit the features of PostgreSQL 10 to design and maintain a high-performance PostgreSQL database. A working knowledge of SQL, and some experience with PostgreSQL will be helpful in getting the most out of this book.Table of ContentsPostgreSQL VersionsDatabase HardwareDatabase Hardware BenchmarkingDisk SetupMemory for Database CachingServer Configuration TuningRoutine MaintenanceDatabase BenchmarkingDatabase IndexingQuery OptimizationDatabase Activity and StatisticsMonitoring and TrendingPooling and CachingScaling with ReplicationPartitioning DataScaling with Replication
