Field Data Architecture
• Change settings or share a field after data was created -> potential data loss.
• Settled on using per-field storage for all fields, data never moves.
Tuesday, April 20, 2010
Database Optimization
• Per Bundle Storagehttp://drupal.org/project/pbs
• Materialized Viewhttp://drupal.org/project/materialized_view

Module Upgrades
• Use Coder and Coder Upgrade module, then start on field issueshttp://drupal.org/project/coder
• Upgrade documentation:http://drupal.org/node/728792

Data Upgrades
• May not be a normal upgrade, likely an upgrade page listing all fields and upgrade status
