Overview

Property	Value
Use Case ID	UC-014
Use Case Name	Bulk User Operations and Management
Module	Identity Management - Bulk Operations
Priority	Medium
Status	Implemented
Version	1.0
Last Updated	January 30, 2026

Description

This use case describes the comprehensive bulk operations functionality that enables administrators to efficiently manage multiple trial users simultaneously. The system supports importing users from CSV files, performing mass updates (trial extensions, deactivations, access grants), sending bulk communications, and exporting filtered user lists. All bulk operations are processed asynchronously with progress tracking, validation, error handling, and audit logging. Administrators can preview changes in dry-run mode and rollback failed operations to maintain data integrity.

- System displays upload form with template download link
- Administrator downloads CSV template if needed
Administrator Uploads CSV File
- Select CSV file (max 10MB, max 10,000 users)
- Optionally specify import options:
  - Trial duration (default or per-row)
  - Default applications to grant
  - Send welcome emails (yes/no)
  - Validation mode (strict/lenient)
System Validates CSV File
- Check file format (UTF-8, comma-delimited)

Alternative Flows

Alt Flow 1: CSV Validation Failures

flowchart TD A[Administrator uploads CSV] --> B[System validates file] B --> C{Validation Result} C -->|Critical Errors| D[Reject entire file] D --> E[Return 400 Bad Request] E --> F[Display validation errors] F --> G[Admin fixes CSV and re-uploads] C -->|Warnings Only| H[Allow with confirmation] H --> I[Show warnings to admin] I --> J{Admin Decision} J -->|Proceed| K[Create job with warnings] J -->|Cancel| L[Admin fixes CSV] C -->|Valid| M[Create import job] style D fill:#ffcccc style M fill:#ccffcc

Critical Errors (Block Import):

Missing required columns (Email, FullName)
Invalid file encoding
Malformed CSV structure
File exceeds size limit (>10MB)
Row count exceeds limit (>10,000)
All emails invalid format

Warnings (Allow with Confirmation):

Some rows have invalid emails (will be skipped)
Duplicate emails within file
Some emails already exist in database
Some application IDs not found
Some trial durations out of range (will use default)

Steps:

System detects validation issues during step 3
If critical errors found:
- Return 400 Bad Request
- Include detailed error report
- Highlight affected rows/columns
- Provide correction guidance
- Administrator fixes and re-uploads
If warnings only:
- Display warnings with row numbers
- Show "X rows will be skipped" message
- Offer "Proceed Anyway" or "Cancel" options
- If proceed: create job and process valid rows only

Alt Flow 2: Bulk Operation with Dry-Run Mode

sequenceDiagram actor Admin as Administrator participant API as Application Manager API participant DB as Identity Database Admin->>API: POST /api/v1/bulk-operations/extend-trial?dryRun=true Note over Admin,API: Preview mode - no actual changes API->>DB: Begin read-only transaction API->>DB: Query selected users API->>API: Calculate changes for each user API->>API: Validate all operations API->>DB: Rollback transaction (no commits) API->>Admin: Return preview results Note over Admin,API: Shows what WOULD happen alt Admin approves Admin->>API: POST /api/v1/bulk-operations/extend-trial (without dryRun) API->>DB: Execute actual changes API->>Admin: Return job ID else Admin cancels Admin->>API: No further action Note over Admin: No changes made end

Steps:

Administrator selects users and bulk action
Administrator clicks "Preview Changes" (dry-run mode)
System executes operation in preview mode:
- Read all user records
- Calculate all proposed changes
- Validate all changes would succeed
- Check for conflicts or constraints
- Generate preview report
- Do not commit any changes
System returns preview report:
- Number of users affected
- List of changes per user (before/after)
- Any validation warnings
- Estimated execution time
Administrator reviews preview
If approved:
- Administrator clicks "Execute"
- System creates actual job (without dry-run flag)
If canceled:
- No job created, no changes made

Alt Flow 3: Partial Failure with Rollback

sequenceDiagram actor Admin as Administrator participant Worker as Background Worker participant DB as Identity Database participant Audit as Audit Service Worker->>DB: Start bulk operation (batch 1/4) Worker->>DB: Process 50 users successfully DB->>Worker: Batch 1 committed Worker->>DB: Start batch 2/4 Worker->>DB: Process 25 users DB--xWorker: Database constraint violation! Worker->>Worker: Detect critical failure Worker->>Audit: Log failure event alt Rollback Enabled (Transactional Operations) Worker->>DB: Rollback batch 2 (not committed) Worker->>DB: Mark job status: PartiallyCompleted Worker->>Admin: Notify: "75 completed, batch 2 failed, batches 3-4 not processed" Note over Admin: Data consistent, partial progress saved else No Rollback (Fail-Open Operations) Worker->>DB: Mark failed users, continue with batch 3 Worker->>Admin: Notify: "175 completed, 25 failed with errors" Note over Admin: Maximum success, failures logged end

Rollback Strategy by Operation Type:

Transactional (Full Rollback):

Bulk role assignments
Bulk password resets
Bulk deactivation (if critical)

Fail-Open (Continue on Error):

Bulk email sending
CSV imports
Bulk trial extensions (already-expired users can fail)

Steps:

Worker processes bulk operation in batches
Critical failure detected in batch N:
- Database connection lost
- Constraint violation that affects all remaining
- Transaction deadlock
If operation type is transactional:
- Rollback current batch (not committed)
- Preserve previously committed batches
- Mark job as PartiallyCompleted
- Store detailed failure information
If operation type is fail-open:
- Log failure for specific records
- Continue processing remaining batches
- Mark individual records as failed
- Complete job with error summary
Administrator notified with:
- Partial completion status
- Error details and diagnostics
- Option to retry failed records
- Manual intervention guidance if needed

Alt Flow 4: Bulk Email Rate Limiting

sequenceDiagram actor Admin as Administrator participant Worker as Background Worker participant Email as Email Service participant Queue as Job Queue Admin->>Queue: Bulk email to 5,000 users Queue->>Worker: Start job loop Send emails in batches Worker->>Email: Send batch (10 emails) Email--xWorker: 429 Too Many Requests Worker->>Worker: Detect rate limit Worker->>Worker: Apply exponential backoff (wait 60s) Worker->>Queue: Report: "Rate limited, retrying..." Note over Worker: Wait 60 seconds Worker->>Email: Retry batch Email->>Worker: Success (10 emails sent) Worker->>Worker: Reset backoff counter end Worker->>Admin: Job completed (took 45 minutes)

Steps:

Bulk email job starts with large user list
Worker sends emails at configured rate (10/second)
Email service returns rate limit error (429)
Worker detects rate limit:
- Pause sending
- Apply exponential backoff: 60s → 120s → 240s
- Report progress as "Rate Limited - Waiting"
After backoff period:
- Retry failed batch
- If successful: reset backoff, continue
- If still rate limited: increase backoff, retry
Job continues until all emails sent
Total time extends but operation completes
Administrator sees: "Email sent to 4,985 users (15 failed permanently)"

Alt Flow 5: Concurrent Bulk Operations Conflict

sequenceDiagram actor Admin1 as Administrator 1 actor Admin2 as Administrator 2 participant API as Application Manager API participant DB as Identity Database Admin1->>API: Bulk extend trial (users 1-100) Admin2->>API: Bulk deactivate users (users 50-150) API->>DB: Check for concurrent operations on same users DB->>API: Conflict detected (50 users overlap) API->>Admin2: 409 Conflict Note over Admin2: "50 users are being modified by another operation" alt Admin2 waits Admin2->>API: Wait for Admin1 operation to complete Note over Admin1: Operation completes Admin2->>API: Retry bulk deactivate API->>DB: No conflicts, proceed else Admin2 adjusts selection Admin2->>API: Exclude conflicting users (101-150 only) API->>DB: No conflicts, proceed end

Steps:

Administrator 1 starts bulk operation on user set A
Administrator 2 starts bulk operation on user set B
System detects overlap between sets A and B
System checks operation compatibility:
- Compatible: Allow concurrent (e.g., both reading)
- Incompatible: Block second operation (e.g., both modifying)
If conflict detected:
- Return 409 Conflict to second administrator
- Include details: "X users are locked by Job ID Y"
- Provide options: wait, adjust selection, or cancel
Administrator can:
- Wait for first operation to complete
- Modify selection to exclude locked users
- Cancel and retry later

Performance Requirements

Metric	Target	Critical Threshold
CSV import processing rate	> 50 users/second	> 20 users/second
Job queue response time	< 500ms	< 2 seconds
WebSocket progress updates	Every 2 seconds	Every 5 seconds
Bulk operation batch size	50-100 records	25 records (minimum)
Email sending rate	10 emails/second	5 emails/second
Export generation time (1,000 users)	< 5 seconds	< 15 seconds
Concurrent bulk operations supported	10 jobs	5 jobs
Job history retention	90 days	30 days (minimum)
Database batch insert time (100 records)	< 1 second	< 3 seconds

Security Considerations

Authorization

Bulk operations require BulkUserOperations permission
Only admins who created job can view results (unless SuperAdmin)
Job results expire after 90 days for data protection
Sensitive data in results files encrypted at rest

Data Protection

CSV files sanitized (remove scripts, XSS attempts)
File size limits enforced (10MB max)
Row count limits enforced (10,000 max)
Rate limiting on API endpoints (10 requests/minute)
Job results only accessible to authorized users

Audit Trail

Every bulk operation logged with:
- Admin user ID and name
- Operation type and parameters
- Timestamp and duration
- Success/failure counts
- Affected user IDs
Individual user modifications logged separately
Audit logs retained for compliance (7 years)

Rollback Safety

Transactional operations support rollback
Rollback window: 24 hours
Rollback requires justification (logged)
Critical operations (deactivation) have confirmation step

Email Security

Rate limiting to prevent abuse (10/second)
Unsubscribe links in all bulk emails
Bounce handling to detect invalid addresses
Spam complaint monitoring
Domain reputation protection

Testing Scenarios

Test Case 1: Successful CSV Import (198/200 Users)

Given: CSV with 200 users, 2 have validation errors
When: Admin uploads CSV and confirms import
Then: Job created, 198 users created successfully, 2 skipped
Verify: Database has 198 new users, results CSV shows 2 errors, welcome emails sent

Test Case 2: Bulk Trial Extension (45 Users)

Given: 45 users selected, extend by 30 days
When: Admin confirms extension
Then: All 45 users have TrialExpirationDate updated (+30 days)
Verify: Application access grants also extended, notification emails sent, audit log updated

Test Case 3: Dry-Run Preview (No Changes)

Given: 100 users selected for deactivation
When: Admin clicks "Preview Changes" (dry-run)
Then: System shows what would change, no database modifications
Verify: Database unchanged, preview accurate, admin can approve or cancel

Test Case 4: Concurrent Bulk Operations Conflict

Given: Admin 1 extends trials for users 1-100
When: Admin 2 tries to deactivate users 50-150
Then: Second operation blocked for overlapping users (50-100)
Verify: 409 Conflict returned, clear error message, suggestion to wait or adjust selection

Test Case 5: Bulk Email with Rate Limiting

Given: 5,000 users selected for bulk email
When: Job starts sending emails at 10/second
Then: Email service rate limits after 500 emails
Verify: Worker applies exponential backoff, retries, completes job (slower), no emails lost

Test Case 6: Job Cancellation Mid-Processing

Given: CSV import job processing 200 users (currently at 50%)
When: Admin cancels job
Then: Job stops gracefully, 100 users already created remain
Verify: Job status: Cancelled, partial results saved, no data corruption

Test Case 7: Failed Batch with Rollback

Given: Bulk password reset for 500 users, database fails at batch 3
When: Worker detects failure
Then: Batch 3 rolled back, batches 1-2 preserved
Verify: 100 users have new tokens, 400 unchanged, admin notified, retry option available

Test Case 8: Large Export (10,000 Users)

Given: Filter matches 10,000 users
When: Admin requests CSV export
Then: Async job created, file generated, download link provided
Verify: Export file accurate, no memory overflow, compressed if large

Test Case 9: CSV with Duplicate Emails

Given: CSV contains duplicate email addresses (rows 5 and 42)
When: Admin uploads CSV
Then: Validation detects duplicate, shows warning
Verify: Only first occurrence processed, second skipped, clear error message

Test Case 10: Bulk Operation Audit Trail

Given: Admin performs bulk deactivation of 78 users
When: Operation completes
Then: Audit log contains 1 bulk operation entry + 78 individual user modification entries
Verify: All audit entries have correct timestamps, admin ID, before/after values

Monitoring and Analytics

Key Metrics to Track

Bulk Operations Per Day: Count by operation type
Job Success Rate: Completed successfully / Total jobs
Average Processing Time: By operation type and record count
CSV Import Success Rate: Users created / Total rows
Email Delivery Rate: Emails delivered / Emails sent (bulk emails)
Job Cancellation Rate: Cancelled jobs / Total jobs
Rollback Frequency: Rollback operations / Total operations
Concurrent Jobs: Active jobs at peak times
Queue Depth: Jobs waiting in queue
Worker Utilization: % of time workers are busy

Alerts

Job processing time > 10 minutes (investigate performance)
Job failure rate > 10% in 1 hour (system issue)
Queue depth > 20 jobs (worker capacity issue)
CSV validation failure rate > 50% (data quality issue)
Email bounce rate > 5% (deliverability issue)
Database connection errors during bulk ops (critical)
Concurrent job conflicts > 5/hour (workflow coordination issue)

Dashboards

Bulk Operations Overview: Jobs by type, status, time period
Performance Metrics: Processing rates, queue times, completion times
Error Analysis: Common errors, affected users, resolution status
Email Deliverability: Send rates, bounce rates, spam complaints
User Impact: Users affected by bulk operations, trial extensions, deactivations

UC-001: Trial User Self-Registration and Access (individual user creation)
UC-005: Administrator Trial User Management (single user operations)
UC-007: Trial User Metrics and Reporting (analytics and insights)
UC-009: Email Notification Management (email templates and delivery)
UC-011: Audit Trail and Compliance Reporting (detailed logging)
UC-013: Background Job Processing (job queue infrastructure)
UC-015: Data Import/Export Utilities (file handling and formats)

Notes and Assumptions

Async by Default: Operations affecting > 100 users always processed asynchronously
Fail-Open Strategy: CSV imports continue processing even if some rows fail (maximize success)
Batch Processing: All bulk operations use batching (50-100 records) for transaction safety
Email Rate Limiting: Respect email service limits (10/second default, configurable)
Job Retention: Job history and results retained for 90 days, then archived
WebSocket Support: Real-time progress updates require WebSocket connection (fallback: polling)
Rollback Limitations: Only transactional operations support rollback; emails cannot be unsent
CSV Format: UTF-8 encoding required, comma-delimited, optional BOM
Large Files: Files > 10MB or > 10,000 rows rejected (contact support for special handling)
Permissions: Separate permissions for different bulk operation types (future enhancement)
