PostgreSQL 10 High Performance [EPUB ebook] 
Expert techniques for query optimization, high availability, and efficient database maintenance

Postgre SQL 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 Postgre SQL 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 Postgre SQL 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 Postgre SQL. Also, using monitoring insight, Postgre SQL 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 Postgre SQL solution while ensuring high performance and high availability
