18. Key Architectural Principles • Stateless Appservers • Database system of record • No Database Definition Language (DDL) at Runtime • All tables partitioned by OrgId • Smart Primary Keys, Polymorphic Foreign Keys • Creative de-normalization and pivoting • Use every RDBMS feature & optimization

19. Metadata, data, and pivot table structures store data corresponding to virtual data structures

20. The Objects table stores metadata about custom objects (tables)

21. The Fields table stores metadata about custom fields (columns)

22. The Data heap table stores all structured data corresponding to custom objects

23. A single slot can store various types of data that originate from different objects

24. The Indexes pivot table manages tenant-specific selective indexes

25. The UniqueFields pivot table facilitates uniqueness for custom fields

26. The Relationships pivot table facilitates referential integrity and optimizes joins

27. All data & metadata structures are partitioned to improve performance and manageability • Tables hash partitioned by OrgId • Separate connection pools point to physical hosts • App tier is also dynamically partitioned by OrgId • Distributed metadata cache with transactional invalidation

28. Application Framework: a whole lot for free • Native Declarative features • Bulk Processing • The Recycle Bin • Full Text Search • Smart Bulk Data Manipulation Language (DML) • Web Services APIs

29. Force.com’s native Application Framework provides declarative development, no coding

30. Validation rules and simple formulas: Business analysts can “code” these

31. Not so simple: Rollup-summary fields provide for easy cross-object summaries

32. Force.com’s bulk processing optimizations reduce overhead for data loads

33. Data definition processing is optimized to avoid performance hits or concurrency limits Examples: • Sort all records by primary key before attempting DML • Operate on tables in deterministic order • Slot reallocation for field datatype change • Deferred calculation for new rollup-summary field • Background processing of mass changes

34. The Recycle Bin: Smart Undeletes  Individual object instances (records) Restore  Related object instances (parent/child records)  Entire fields and objects (dropped columns and tables)

35. Multitenant Search, anything but simple Replication Index Backup Primary Instance DR Instance

36. Multitenancy delivers Blazing Performance Transactions Per Quarter 131B Transactions in Q2FY15 51% YOY Growth Average Page Time 217ms Latency in Q2FY15 13% YOY Improvement

37. Multitenant Core Data Storage Production RAC Cluster • 4 Online copies of database • 2 Online backup copies Production RAC Cluster Async Replication Data Guard Replication Data Guard Replication Application Servers Application Servers Standby RAC Cluster Primary Instance Standby RAC Cluster Secondary Instance

38. Multitenant Query Optimization Principles • Consistent SQL generation across the application • Deep awareness of pivot table structure – • Flex schema does impose a cost Tenant, user, object, fields statistics are crucial • No runaway queries allowed • Deep integration with the sharing model

39. Multitenant Query Optimizer Run Pre-Queries Check user visibility Search originates from API or global search Check filer selectivity Dynamically write query based on pre- queries user visibility = number of rows user can access filter selectivity = index corresponding to filter column Execute optimized query return results

40. The optimizer considers pre-query selectivity measurements when writing a query Pre-Query Selectivity Measurements Write final database access query, forcing … User Filter Low Low … nested loops join; drive using view of rows that the user can see. Low High … use of index related to filter. High Low … ordered hash join; drive using Data table. High High … use of index related to filter.

41. Apex: Force.com’s procedural frontier Variable Declaration Commit Transaction Control Structure Array Data Operation Integer NUM = 10; Account[] accs; SOQL Query // Clean up old data accs = [select id from account where name like 'test%']; delete accs; commit; accs = new Account[NUM]; for (Integer i = 0; i < NUM; i++) { accs[i] = new Account(name='test ' + i, outstandingshares__c=i); } insert accs; Contact[] cons = new Contact [0]; for (Account acc : accs) { cons.add(new Contact(lastName=acc.name + '1', accountid=acc.id)); cons.add(new Contact(lastName=acc.name + '2', accountid=acc.id)); } insert cons;

42. Apex code is stored as metadata, interpreted at runtime, and cached for scalability

43. Apex is deeply integrated with platform features • Bulk DML • Email and messaging • Asynchronous processing (Futures) • XmlStream / HTTP (RESTful) services classes • Declarative exposure as new Web Services
