Key benefits

Learn the right techniques to obtain optimal PostgreSQL database performance, from initial design to routine maintenance

Discover the techniques used to scale successful database installations

Avoid the common pitfalls that can slow your system down

Filled with advice about what you should be doing; how to build experimental databases to explore performance topics, and then move what you've learned into a production database environment

Covers versions 8.1 through 9.0

Description

PostgreSQL database servers have a common set of problems they encounter as their usage gets heavier and requirements more demanding. You could spend years discovering solutions to them all, step by step as you encounter them. Or you can just look in here.All successful database applications are destined to eventually run into issues scaling up their performance. Peek into the future of your PostgreSQL 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, with the right indexes. Monitor every layer, from hardware to queries, using some tools that are inside PostgreSQL and others that are external. Using monitoring insight, continuously rework the design and configuration. On reaching the limits of a single server, break things up; connection pooling, caching, partitioning, and replication can all help handle increasing database workloads. The path to a high performance database system isn't always easy. But it doesn't have to be mysterious with the right guide.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

I've also read the companion PostgreSQL 9 Admin Cookbook. The Admin cookbook is an easier read, but this book had a lot more information I was unaware of and probably hit my weaker knowledge spots. There is very little overlap between the two books.What surprised me most about this book was how much of it is not specific to PostgreSQL, but in fact hardware considerations and testing that are pertinent to most relational databases. In that sense I wouldn't limit my recommendation to just PostgreSQL, but also to anyone using a relational database on Unix/Linux for a high load project.The PostgreSQL 9 High Performance book isn't going to teach you too much about writing better queries,day to day management (which is more of the focus of the Admin Book), or how to load data etc, but it will tell you how to determine when your database is under stress or your hardware is failing and adversely affecting your queries and what is causing that stress. It will also provide rules of thumb as to how to pick the best hardware for your project and budget, how to partition your data, what disks to put what kind of data. Various tuning and benchmarking techniques for highload testing.

Nur einige Highlights:Viele glauben je mehr shared memory eine Datenbank hat, desto besser. Falsch! Greg erklärt wieso und welche durchaus negativen Effekte zu viel shared memory hat.In meiner Datenbank hatte ich eine Tabelle, für die der Planner je nach Parameterkombination eines Selects sehr unterschiedliche Pläne erzeugen konnte. Bevor ich das Buch gelesen hatte, hatte ich mit den verschiedenen Cost-Parametern gespielt, ohne Erfolg. Um den idealen Plan zu erzwingen, konnte ich je nach Parameterkombination entweder seqscans verbieten, oder Hashjoins oder Ähnliches. Eine andere Möglichkeit den Planner zur Benutzung bestimmter Idizes zu bewegen, war ein spezieller Tablespace mit anderen Cost-Parametern für diese Indizes. Nach dem Lesen des Buches, war mir klar, wo der Fehler lag und welche Schraube zu drehen ist, ohne zu solchen Tricks zu greifen.Greg beleuchtet alle Bereiche, die für die Performance einer Postgres DB entscheidend sind, angefangen von der Hardware über Platten/RAID, das Betriebssytem und die Auswahl des Filesystems bis hin zu den Konfigurationsparametern natürlich. Ich hätte mir mehr über SSD und z.B. BTRFS gewünscht. Das Buch wurde jedoch schon 2010 veröffentlicht. Damals gab es einfach nicht genügend Erfahrung.Sicher findet man all die Information in dem Buch auch irgendwo im Internet. Doch auf diese Weise dauert es einfach deutlich länger, bis man versteht. Das Buch gehört definitiv in das Regal eines jeden Postgres Admins, der mehr als ein paar hundert MB an Daten zu verwalten hat.

Excellent book. Very well written and pleasant to read.Provides a lot of details that help to actually understand what is going on in database. Every performance/optimization technique, configuration flag is explained in detail.First half of the book covers thinks like choosing hardware, processor, memory, disk, file system, RAID matrix ,etc. In spite of the fact that I am java programmer, not DB engineer I find this part interesting too; it is good to know how database does its job.Somewhat old (addresses postgreSQL 9.0 and older versions, we have 9.4 now), but I see no parts that are outdated. PostgreSQL have not changed that much (you may read release notes for 9.1-9.4) and basic principles (that are explained very well, in length and in great detail) are not to change anytime soon.
