CHAPTER 25 • INTRODUCING MYSQLwww.it-ebooks.infoMySQL 5.4 and 5.5The first releases made available following the company’s acquisition, these development versionsprimarily include a number of performance-related enhancements. It is unclear when version 5.5 will beofficially released, so you should base your development on the official 5.1 release.Prominent MySQL UsersAs mentioned, MySQL boasts quite a list of prominent users. I’ve chosen two of the more compellingimplementations to offer additional insight into how MySQL can help your organization.craigslistThe popular online classifieds and community site craigslist (www.craigslist.org) has beencontinuously expanding since it was founded in 1995. The craigslist site has depended upon the LAMP(Linux, Apache, MySQL, Perl) stack since its inception, and MySQL has demonstrated its scalabilitythroughout the site’s history as it grew from a hobby of founder Craig Newmark to one of the Web’s mostpopular sites, presently processing more than 9 billion page views per month (seewww.craigslist.org/about/pr/factsheet.html). Each month, craigslist adds more than 30 million users,processes more than 30 million new classified ads, and disseminates more than 2 million new joblistings.According to a MySQL case study titled “craigslist Relies on MySQL to Serve Millions of ClassifiedAds” (www.mysql.com/why-mysql/case-studies/mysql-craigslist-casestudy.pdf), craigslist dependsupon MySQL to run every database-driven aspect of the site. Of particular interest is the use of MySQL‘sfull-text search capabilities for the site’s search feature. Consult the case study for a completebreakdown of MySQL’s impressive role in running one of the most popular web sites in the world.WikipediaFounded in January 2001, the volunteer-driven online encyclopedia Wikipedia: The Free Encyclopedia(www.wikipedia.org) has grown from a personal project founded by Jimmy Wales to one of the top tenmost trafficked sites on the Web (according to www.alexa.com/). The site is truly an endless font ofknowledge, contributed by informed and enthusiastic individuals from all over the world.To put Wikipedia’s growth into perspective, a previous edition of this book referred to Wikipedia’suse of five MySQL servers to power the site. Today, Wikipedia uses approximately 150 MySQL servers toprocess an average of almost 49,000 requests per second(http://en.wikipedia.org/wiki/Wikipedia:Statistics).Other Prominent UsersThe MySQL website offers a laundry list of case studies featuring high-profile MySQL users(http://mysql.com/why-mysql/case-studies/), among them Ticketmaster.com, Walmart, Zappos, andAdobe. Consider taking some time to peruse these summaries as they can serve as useful ammunitionwhen lobbying your organization to adopt MySQL within the enterprise.484
