Field of Dreams

If you build it, it will have fields.– Users– Comments– Nodes– Terms– What will you build next? Entity API

EntityQueryAPIReplacing: content_profile, node_comments, node auto term (NAT), countless others.

Geeks are people too. DX++

Massive improvements in the names of hooks / API functions– No more node_api– No more hook_block

DBTNG makes working with your database a joy – Hint: no more SQL.– $query =

db_select(‘node’, ‘n’) ->fields(‘n’, ‘title’) ->condition(‘n.created’, time() - 60 * 60, ‘>’);

Install profiles are like modulesPrivate AND public file handling.

Not just a nerdfest, also a pretty face!

jQuery UI in core!New flexibility in theming, pre_process hooks, page array.Color module in core.Admin theme in core, consistent design and predictable user experienceStark - base theme in core, good starting point.

Scaling and Performance

Scaling: Growing bigger– More data– More users– More traffic

Performance: Going faster– Fewer queries– Faster queries– Faster page loads

Scaling = Handling Big Data

Web nodes are generally stateless and thus easy to scaleLong term trend in scalability has been the ability to manage more data– Single SQL server– Master/slave SQL– Memory-based key/value stores (memcached)– Non-relational persistent databases (MongoDB,

Cassandra, ...)

Scaling with Drupal 7

More ways to put more data in more places– Slave database servers

Modules identify which queries are slave-able– db_select(‘node’, ‘n’, array(‘target’ => ‘slave’))

– Multiple cache back-endsSession in memcache, watchdog in MongoDB, page cache in SQL, ...

– Pluggable Field API data storageStore in SQL or NoSQL enginesStore in different locations by field / typeAccess completely remote data as a field

Performance

Faster content writes and reads with Field API pluggable storageCaching proxy support (e.g. Varnish)– Session-less anonymous users– HTTP Cache-Control headers

Multi-load queries– SELECT cols WHERE id IN (a, b, c, ...)– Reduces number of queries per page load

Block caching– Blocks declare themselves as cacheable globally, by page,

role, or user, or not at all
