On his side, Baron has written client software that enhances the usability of MySQL. The authors’ backgrounds are clearly reflected in their complete reworking in this second edition of High Performance MySQL: Optimizations, Replication, Backups, and More. It’s not just a book that tells you how to optimize your work to use MySQL better than ever before. The authors have done considerable extra work, car- rying out and publishing benchmark results to prove their points. This will give you, the reader, a lot of valuable insight into MySQL’s inner workings that you can’t eas- ily find in any other book. In turn, that will allow you to avoid a lot of mistakes in the future that can lead to suboptimal performance. I recommend this book both to new users of MySQL who have played with the server a little and now are ready to write their first real applications, and to experi- enced users who already have well-tuned MySQL-based applications but need to get “a little more” out of them. —Michael Widenius March 2008 ix Preface2 We had several goals in mind for this book. Many of them were derived from think- ing about that mythical perfect MySQL book that none of us had read but that we kept looking for on bookstore shelves. Others came from a lot of experience helping other users put MySQL to work in their environments. We wanted a book that wasn’t just a SQL primer. We wanted a book with a title that didn’t start or end in some arbitrary time frame (“...in Thirty Days,” “Seven Days To a Better...”) and didn’t talk down to the reader. Most of all, we wanted a book that would help you take your skills to the next level and build fast, reliable systems with MySQL—one that would answer questions like “How can I set up a cluster of MySQL servers capable of handling millions upon millions of queries and ensure that things keep running even if a couple of the servers die?” We decided to write a book that focused not just on the needs of the MySQL appli- cation developer but also on the rigorous demands of the MySQL administrator, who needs to keep the system up and running no matter what the programmers or users may throw at the server. Having said that, we assume that you are already rela- tively experienced with MySQL and, ideally, have read an introductory book on it. We also assume some experience with general system administration, networking, and Unix-like operating systems. This revised and expanded second edition includes deeper coverage of all the topics in the first edition and many new topics as well. This is partly a response to the changes that have taken place since the book was first published: MySQL is a much larger and more complex piece of software now. Just as importantly, its popularity has exploded. The MySQL community has grown much larger, and big corporations are now adopting MySQL for their mission-critical applications. Since the first edi- tion, MySQL has become recognized as ready for the enterprise.* People are also * We think this phrase is mostly marketing fluff, but it seems to convey a sense of importance to a lot of people.

  • Beyond Relational Databases
    EXPERT ANALYSIS BY MARCOS ALBE, SUPPORT ENGINEER, PERCONA Beyond Relational Databases: A Focus on Redis, MongoDB, and ClickHouse Many of us use and love relational databases… until we try and use them for purposes which aren’t their strong point. Queues, caches, catalogs, unstructured data, counters, and many other use cases, can be solved with relational databases, but are better served by alternative options. In this expert analysis, we examine the goals, pros and cons, and the good and bad use cases of the most popular alternatives on the market, and look into some modern open source implementations. Beyond Relational Databases Developers frequently choose the backend store for the applications they produce. Amidst dozens of options, buzzwords, industry preferences, and vendor offers, it’s not always easy to make the right choice… Even with a map! !# O# d# "# a# `# @R*7-# @94FA6)6 =F(*I-76#A4+)74/*2(:# ( JA$:+49>)# &-)6+16F-# (M#@E61>-#W6e6# &6EH#;)7-6<+# &6EH# J(7)(:X(78+# !"#$%&'( S-76I6)6#'4+)-:-7# A((E-N# ##@E61>-#;E678# ;)762(# .01.%2%+'.('.$%,3( @E61>-#;(F7# D((9F-#=F(*I## =(:c*-:)U@E61>-#W6e6# @F2+16F-# G*/(F-# @Q;# $%&## @R*7-## A6)6S(77-:)U@E61>-#@E-N# K4E-F4:-A%# A6)6E7(1# %49$:+49>)+# @E61>-#'*1-:-# @E61>-#;6<R6# L&H# A6)6#'68-# $%&#@:6F521+#M(7#@E61>-#;E678# .761F-#;)7-6<#LNEF(7-7# S-76I6)6#=F(*I# A6)6/7418+# @ !"#$%&'( ;H=JO# ;(\X67-#@D# M(7#J6I((E# .761F-#%49#A6)6#=F(*I# @ )*&+',"-.%/( S$%=.#;)7-6<%6+-# =F(*I-76# LF6+21+-671># ;G';)7-6<# LF6+21#[(*:I# @E61>-#;"# @E61>-#;)(7<# H618+E61-# *&'+,"#$%&'$#( .761F-#%49#A6)6#@EEF46:1-#

  • XAMPP Web Development Stack
    XAMPP Web Development Stack Overview @author R.L. Martinez, Ph.D. The steps below outline the processes for installing the XAMPP stack on a local machine. The XAMPP (pronounced Zamp) stack includes the following: Apache HTTP Server, MariaDB (essentially MySQL), Database Server, Perl, and the PHP Interpreter. The “X” in XAMPP is used to signify the cross-platform compatibility of the stack. The Apache HTTP Server and PHP are required to run phpMyAdmin which is a PHP application that is used for database administration tasks such as creating databases and tables, adding users, etc. Alternative to XAMPP If you have experience with MySQL Workbench, you may prefer to install MySQL Server and MySQL Workbench via the MySQL Installer. MySQL Workbench performs the same functions as phpMyAdmin. However, unlike phpMyAdmin which is a web-based application, MySQL Workbench is a locally installed application and therefore does not require an HTTP Server (e.g. Apache) to run. Installing XAMPP Many of the steps listed have several alternatives (such as changing MySQL passwords via a command line) and students are welcomed and encouraged to explore alternatives. 1. Download XAMPP from the URL below and place the installer (.exe) in the location where you want to install XAMPP. Placing the installer (.exe) in the same location as the intended installation is not required but preferred. http://www.apachefriends.org/download.html Page 1 of 17 XAMPP Web Development Stack 2. See the warning which recommends not installing to C:\Program Files (x86) which can be restricted by UAC (User Account Control). In the steps below XAMPP is installed to a USB flash drive for portability.

  • Mariadb Presentation
    THE VALUE OF OPEN SOURCE MICHAEL ”MONTY” WIDENIUS Entrepreneur, MariaDB Hacker, MariaDB CTO MariaDB Corporation AB 2019-09-25 Seoul 11 Reasons Open Source is Better than Closed Source ● Using open standards (no lock in into proprietary standards) ● Resource friendly; OSS software tend to work on old hardware ● Lower cost; Usually 1/10 of closed source software ● No cost for testing the full software ● Better documentation and more troubleshooting resources ● Better support, in many cases directly from the developers ● Better security, auditability (no trap doors and more eye balls) ● Better quality; Developed together with users ● Better customizability; You can also participate in development ● No vendor lock in; More than one vendor can give support ● When using open source, you take charge of your own future Note that using open source does not mean that you have to become a software producer! OPEN SOURCE, THE GOOD AND THE BAD ● Open source is a better way to develop software ● More developers ● More spread ● Better code (in many cases) ● Works good for projects that can freely used by a lot of companies in their production or products. ● It's very hard to create a profitable company developing an open source project. ● Not enough money to pay developers. ● Hard to get money and investors for most projects (except for infrastructure projects like libraries or daemon services). OPEN SOURCE IS NATURAL OR WHY OPEN SOURCE WORKS ● You use open source because it's less expensive (and re-usable) ● You solve your own problems and get free help and development efforts from others while doing it.

  • ZRM for Mysql Performance Benchmarks
    Backup and recovery benchmarks for MyISAM and InnoDB engines with Zmanda Recovery Manager for MySQL. By Dmitri Joukovski and Shailen Patel "As MySQL gains widespread adoption and moves more broadly into the enterprise, ZRM for MySQL addresses the growing need among database administrators to protect their digital assets with a comprehensive backup and recovery solution. Zmanda is a valued member of MySQL's ecosystem, and their open source backup solutions are an excellent complement to MySQL's open source database offerings." Marten Mickos, CEO of MySQL AB. Abstract This document provides backup and recovery benchmarks for MyISAM and InnoDB engines with logical, raw and snapshot methods of backup available in ZRM for MySQL. Please send your comments to [email protected] The MySQL database has become the world's most popular open source database because of its consistent fast performance, high reliability and ease of use. The DBAs also expect performance, robustness and ease of use from a backup solution for MySQL. Often times we are asked what performance to expect from Zmanda Recovery Manager (ZRM) for MySQL. This document describes our first results in measuring ZRM backup and recovery performance. Testing configuration 2 x 2.8Ghz/800 FSB Xeon server 4GB ECC/Registered 333Mhz RAM 9500S-12MI 3Ware SATA Controller 230 GB RAID 1 system array 2.27 TB RAID 0 data array All Disks 7200 RPM Operating System - Red Hat Enterprise Linux AS 4 with 2.6.12 kernel Backup of MySQL version 5.0 database MyISAM and InnoDB storage engines Version 1.1 of Enterprise Edition ZRM for MySQL According to 3Ware, the 9500 SATA controller supports a transfer rate of approximately 400 MB/s.
