11. Field of Dreams
If you build it, it will have fields.
– Users
– Comments
– Nodes
– Terms
– What will you build next? Entity API
EntityQueryAPI
Replacing: content_profile, node_comments, node
auto term (NAT), countless others.

12. 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 modules
Private AND public file handling.

13. 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 experience
Stark - base theme in core, good starting point.

15. Scaling and Performance
Scaling: Growing bigger
– More data
– More users
– More traffic
Performance: Going faster
– Fewer queries
– Faster queries
– Faster page loads

16. Scaling = Handling Big Data
Web nodes are generally stateless and thus easy to
scale
Long 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, ...)

17. 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-ends
Session in memcache, watchdog in MongoDB, page cache in
SQL, ...
– Pluggable Field API data storage
Store in SQL or NoSQL engines
Store in different locations by field / type
Access completely remote data as a field

18. Performance
Faster content writes and reads with Field API
pluggable storage
Caching 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
