Notes

• Make tags object agnostic (i.e. allow tagging users, partitions, etc. together with a single tag).
• Consider using InnoDB for several tables where ACID compliance is important.
  • Also allows simplification of table relationships with real foreign keys and constraints.
• Replace *_changes tables with a unified and more comprehensive generic log table.
  • Decide which log items should expire over time.
