Interactive Transactions
Use the $transaction callback API for operations that must succeed or fail atomically. Interactive transactions provide automatic rollback on errors and allow complex multi-step logic.
When to Use
Use interactive transactions when:
- Multiple operations must all succeed or all fail
- Operations depend on results from previous operations
- Complex business logic requires atomic execution
- Implementing financial transfers, inventory management, or state changes
Do NOT use for:
- Single operations (no transaction needed)
- Read-only operations (use batch queries instead)
- Independent operations that can fail separately
