   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
