kappa 04dcb57fae feat(schema): 데이터베이스 스키마 강화 마이그레이션
데이터 무결성:
- user_deposits.balance >= 0 CHECK 제약조건
- deposit_transactions.depositor_name 최대 50자 제한
- 음수 잔액 방지, 긴 이름 방지

감사 추적:
- audit_logs 테이블 생성
- 모든 중요 작업 추적 (user_id, action, resource, details)
- 인덱스 추가 (user_id, action, created_at)

프로덕션 안전:
- 백업 → 재생성 → 복원 방식
- 롤백 스크립트 포함
- 데이터 유실 방지 로직
- 음수 잔액 데이터 감지 및 로그

마이그레이션 파일:
- migrations/001_schema_enhancements.sql (5.5K)
- migrations/001_rollback.sql (4.0K)
- migrations/AUDIT_LOG_EXAMPLES.ts (11K)
- migrations/TEST_RESULTS.md (8.0K)
- migrations/README.md (2.8K)

문서:
- SCHEMA_MIGRATION_GUIDE.md (13K) - 완전한 배포 가이드
- MIGRATION_SUMMARY.md (9.1K) - 요약 및 체크리스트

로컬 테스트 결과:
-  마이그레이션 성공 (23 commands, <1초)
-  CHECK 제약조건 작동 (음수 잔액 거부)
-  길이 제한 작동 (51자 이름 거부)
-  audit_logs 테이블 정상
-  데이터 보존 확인 (users:3, deposits:1, transactions:1)
-  음수 잔액 데이터 감지 (user_id:3, balance:-500)

프로덕션 배포:
- 로컬 테스트 완료, 프로덕션 준비 완료
- 배포 전 백업 필수
- 예상 소요 시간: <5분

Database Migrations

This directory contains database migration scripts for the Telegram Bot Workers project.

Files

File Purpose
001_schema_enhancements.sql Migration script - adds CHECK constraints and audit logging
001_rollback.sql Rollback script - reverts migration 001
AUDIT_LOG_EXAMPLES.ts TypeScript examples for using audit logs
TEST_RESULTS.md Local test results and verification
README.md This file

Quick Start

Local Testing

# Initialize local database
npm run db:init:local

# Add test data
wrangler d1 execute telegram-conversations --local \
  --command "INSERT INTO users (telegram_id, username) VALUES ('123', 'test')"

# Run migration
wrangler d1 execute telegram-conversations --local \
  --file migrations/001_schema_enhancements.sql

# Verify constraints work
wrangler d1 execute telegram-conversations --local \
  --command "INSERT INTO user_deposits (user_id, balance) VALUES (999, -1000)"
# Expected: CHECK constraint failed

Production Deployment

⚠️ MANDATORY: Read SCHEMA_MIGRATION_GUIDE.md first

# 1. Backup database
wrangler d1 execute telegram-conversations \
  --command ".dump" > backup_$(date +%Y%m%d_%H%M%S).sql

# 2. Run migration
wrangler d1 execute telegram-conversations \
  --file migrations/001_schema_enhancements.sql

# 3. Verify success
wrangler d1 execute telegram-conversations \
  --command "SELECT 'Migration completed' as status, datetime('now') as timestamp"

Migration 001: Schema Enhancements

Date: 2026-01-19

Changes

  1. user_deposits: Add balance >= 0 CHECK constraint
  2. deposit_transactions: Add depositor_name length <= 50 CHECK constraint
  3. audit_logs: Create new table for operation tracking

Benefits

  • Prevent negative balances at database level
  • Enforce depositor name length limit
  • Track all critical operations for compliance and debugging
  • Improved data integrity and auditability

Risk Level

  • Low: No breaking changes to application code
  • No downtime: Migration completes in < 1 second for typical datasets
  • Reversible: Rollback script available

Files

  • Migration: 001_schema_enhancements.sql
  • Rollback: 001_rollback.sql
  • Guide: ../SCHEMA_MIGRATION_GUIDE.md
  • Examples: AUDIT_LOG_EXAMPLES.ts
  • Tests: TEST_RESULTS.md

Documentation

For detailed information, see:

  • SCHEMA_MIGRATION_GUIDE.md: Complete deployment guide
  • TEST_RESULTS.md: Local test results and verification
  • AUDIT_LOG_EXAMPLES.ts: Usage examples for audit logs

Support

If issues occur during migration:

  1. Check logs: wrangler tail
  2. Review SCHEMA_MIGRATION_GUIDE.md troubleshooting section
  3. Rollback if necessary: 001_rollback.sql
  4. Restore from backup if critical failure
