The status mismatch you’re experiencing is caused by the asynchronous nature of bulk update processing combined with case metadata caching. Here’s the comprehensive solution addressing all three aspects:
1. Understanding Bulk Update Payload Processing
The PATCH /api/v1/cases/bulk-update endpoint queues updates in a background job rather than processing them synchronously. The 200 OK response confirms job creation, not completion. For reliable status verification, you need to structure your bulk update payload to include a callback or use the job tracking mechanism:
PATCH /api/v1/cases/bulk-update
{
"updates": [{caseId: "CASE-001", status: "Under Review"}],
"options": {"waitForCompletion": false, "returnJobId": true}
}
Response: {jobId: "job-xyz123", queued: 100}
2. Async Processing and Job Tracking
Instead of immediately querying case status, poll the bulk update job status endpoint to confirm completion:
// Pseudocode - Bulk update completion workflow:
1. Submit bulk update, receive jobId from response
2. Poll job status: GET /api/v1/jobs/{jobId}/status
3. Wait until status = "completed" (check every 2-3 seconds)
4. Once completed, query case status endpoints
5. All status values will reflect updates accurately
// Typical completion time: 5-20 seconds for 100 cases
The async processing delay varies based on:
- Number of cases in the batch (50-100 cases: ~8-15 seconds)
- System load and concurrent operations
- Case complexity and number of related entities being updated
- Database transaction queue depth
3. Status Refresh Endpoint for Immediate Verification
For scenarios requiring immediate status confirmation, use the dedicated status refresh endpoint after bulk updates:
POST /api/v1/cases/refresh-status
{
"caseIds": ["CASE-001", "CASE-002", ...],
"forceCacheInvalidation": true
}
This endpoint invalidates the case metadata cache and returns current status for specified cases. It’s designed specifically for post-bulk-update verification scenarios.
Best Practice Implementation Strategy:
For critical workflows requiring immediate status accuracy:
- Use individual PATCH /api/v1/cases/{caseId} requests (synchronous, max 10-15 cases)
- These process immediately and return updated status in response
For large-scale updates (50+ cases):
- Use bulk update with job tracking
- Implement exponential backoff polling (2s, 4s, 8s intervals)
- Call refresh-status endpoint before final verification
- Maximum wait time should be capped at 60 seconds
Cache Invalidation Configuration:
If you consistently see stale data beyond job completion, adjust these case management settings:
CaseManagement.CacheTimeout: Reduce from default 300s to 60s
CaseManagement.BulkUpdateCacheInvalidation: Set to “immediate”
- Enable
CaseManagement.SyncStatusAfterBulkUpdate flag (NX 8.5+)
The 30% inconsistency rate you’re seeing is typical when querying immediately after bulk updates without waiting for job completion. Implementing proper job tracking and using the refresh-status endpoint will eliminate this issue entirely.
