This speech will be focused on non standard practices for Drupal sites 'cooking'. The main aspects of the speech are: Page building with Apache Solr data storage, REST API on the back-end side and Angular JS on the front-end side. How to handle Solr data storage via REST API: - Referenced entities - Responsive images - Menus and site settings - Cache and it's invalidation - Access and permissions - 403 & 404 exceptions Search results based on REST response: filters, facets and sorting. Managing 10000+ domains on one site.

15. Solr? NoSQL?
▸ CP system
(consistent and partially tolerant)
▸ Document oriented
▸ Indexed in sophisticated way
(search across all fields or specific)
▸ No fixed schemas
(fixed schemas as well)
▸ Avoid joins
▸ Marketing

16. “Genre is about marketing”

17. ▸ Scalability
▸ Realtime-Get
▸ Search (facets)
▸ Very similar to MongoDB
▸ Update Durability
▸ Versioning and optimistic locking

PRE-COOK
SOLR Backend
Enhanced contrib
backend solution:
avoid building full
field structure on
results extracting.
SOLR Processors
For some specific
data we need
specific format of
storing.

24. REAL SEARCH PAGES
▸ Partly using Search API (custom Solr
backend plugin and query builder)
▸ Direct facets (avoid using Facets
module)

ROUTES
▸ Own ParamConverter
▸ Project specific settings for routes
(building route per entity type/bundle/etc.)
▸ Handling 403/404 errors
(via Fast404 module & custom Fast403)

34. DOMAINS
▸ Huge amount of breeders
(70k, 8k active, 300 clubs)
▸ Menu per domain
▸ Config entities problems
▹ domainNegotiator
▹ CacheContext
▹ path processors
▹ extending Domain Entity

35. DOMAIN
