> Hi all, > > I've been tinkering with caching a lot recently, so I have started a series > of proposals to assist developers in integrating caching into their Zend > Framework applications. To get the process going I have proposed two new > Zend_Cache backends: > > Zend_Cache_Backend_Static > http://framework.zend.com/wiki/pages/viewpage.action?pageId=8947732 > > A simple means of caching pages into static HTML files, and includes a > tagging system to offset the major disadvantage of static caching which is > of course expiring/invalidating the files without needing to manually track > them all by hand. The power of a static file cache is that it is far faster > than the current Page cache even with a memory backend. It also removes the > need for a caching proxy like Squid. It's widely recognised as one of the > fastest caching strategies possible for web applications since it completely > avoids PHP and lets the HTTP server reach it maximum potential throughput by > avoiding any unnecessary processing. > > Zend_Cache_Backend_Database > http://framework.zend.com/wiki/pages/viewpage.action?pageId=9437191 > > Offers a nice database backed cache for data which requires longer term > caching. This creates a persistent cache which does not rely on the > filesystem, scales well, and which is not exposed to the volatility of > memory caching (because then stuff vanishes mysteriously when you switch off > machines :)). Database caching is obviously slow but there are a lot of > precedents. Just for starters, have a look at where Zend_Openid can store > time limited association data! Often a database cache is used as a more > dependable secure cache which can be re-cached into memory (without fear of > losing any of the data) for faster access as part of a layered cache system. > > Future proposals will move towards an approach of expanding caching > strategies available from the framework, and integrating those caches and > easy to use APIs deeper into the framework through a mix of helpers and > plugins. The goal is to minimise setup source code and development time, and > offer a complete cache management subsystem available from all levels of the > application. > > I hope these first proposals meet with the community's approval and I > invite any comments. > > Thanks! > > Paddy > > Pádraic Brady > > http://blog.astrumfutura.com > http://www.survivethedeepend.com > OpenID Europe Foundation Irish Representative<http://www.openideurope.eu/> > > -- Xavier Vidal Piera Director Tècnic de Citrusparadis.com - Grupo Intercom Enginyer Tècnic Informàtic de Gestió Tècnic Especialista Informàtic d'equips xavivi...@gmail.com http://web.xaviervidal.net 610.68.41.78
