Transcript

1. Meet Magento Poland 2014 Meet Magento Poland 2014 Marko Martinović Magento 2 Caching Strategies
2. Meet Magento Poland 2014 2.0 Platform Goals “Improved performance and scalability”
3. Meet Magento Poland 2014 Architecture Built on top of Zend_Cache
4. Meet Magento Poland 2014 Architecture Multiple frontend pools, each associated to one or two level backend adapter
5. Meet Magento Poland 2014 Architecture Each cache type with its own class enforcing specific cache tag
6. Meet Magento Poland 2014 Frontend Pools Out the box: • default - General type instances • page_cache - PageCache type instance
7. Meet Magento Poland 2014 Backend Adapters Cm_Cache_Backend_File as the default cache backend
8. Meet Magento Poland 2014 Backend Adapters All the usual suspects, with MongoDB adapter introduced
9. Meet Magento Poland 2014 Cache Types Good old • Configuration • Layouts • Blocks HTML output • Collections data • EAV types and attributes • Translations Brand New • View files fallback • View files pre- processing • Integrations Configuration • Integrations API Configuration • Web Services Configuration • PageCache
10. Meet Magento Poland 2014 Collections Data Fetch strategy interface with Query and Cache implementations
11. Meet Magento Poland 2014 Collections Data Store, Store Group, Website and Catalog Category collection cached
12. Meet Magento Poland 2014 EAV Types and Attributes Implemented to cache eav_entity_type table collection. Still here, still unused, still no one knows why.
13. Meet Magento Poland 2014 EAV Types and Attributes "One developer is working on it for a month, other comments it out for testing, third one is then afraid to enable it back" -Ivan Weiler @Inchoo
14. Meet Magento Poland 2014 View Files Fallback Requested asset is being searched for using fallback rules applied to fallback context
15. Meet Magento Poland 2014 View Files Fallback Path to requested asset resolved and cached
16. Meet Magento Poland 2014 View Files Pre-processing Pre-processing of Magento-flavoured CSS tricks like @magento_import, @import, scope notation file references and Less
17. Meet Magento Poland 2014 View Files Pre-processing Path to pre-processed asset cached
18. Meet Magento Poland 2014 PageCache Out the box: • PHP/AJAX based (Built-in) • Reverse proxy/ESI/AJAX based (Varnish)
19. Meet Magento Poland 2014 PageCache Caching controlled by ‘Cache-Control’: public, max-age=XY, s-maxage=XY vs. private, max-age=YZ vs. no-store, no-cache, must-revalidate, max- age=0
20. Meet Magento Poland 2014 PageCache Setting cacheable=false to some block results with whole page not being cached
21. Meet Magento Poland 2014 Hole Punching Setting _isScopePrivate to some block results with its content not being cached
22. Meet Magento Poland 2014 Hole Punching Setting ttl to some block results with its content being served through ESI and cached by Varnish
23. Meet Magento Poland 2014 Built-in Page cache saved through dedicated frontend instance by PHP code
24. Meet Magento Poland 2014 Built-in Dynamic blocks not cached and served exclusively through AJAX: <!-- BLOCK header --><li class="greet welcome">Default welcome msg!</li><!-- /BLOCK header -->
25. Meet Magento Poland 2014 Built-in Pros • Works out the box with no special setup Cons • Leaves a lot to be desired performance- wise
26. Meet Magento Poland 2014 Varnish
27. Meet Magento Poland 2014 Varnish Page cache maintained and served by reverse proxy
28. Meet Magento Poland 2014 Varnish Without ttl set, dynamic blocks not cached and served through AJAX
29. Meet Magento Poland 2014 Varnish With ttl set, dynamic blocks cached and served through ESI: <esi:include src="..." />
30. Meet Magento Poland 2014 Varnish Pros • The best performing caching solution, if properly configured Cons • The worst performing caching solution, if configured improperly • Considerable setup and maintenance overhead • Requires SSL termination proxy to support HTTPS
31. Meet Magento Poland 2014 Benchmarks Magento 2 (Alpha 102) Magento EE (1.14.0.1)
