Attachments with unsupported MIME types are skipped during ingestion.
File Size Limitations
Attachments are subject to the following size limits. Files exceeding these limits are skipped.
File Type
Size Limit
PDF & Documents
100 MB
Images
20 MB
All other supported formats
4 MB
Last Modified Time
Outdated content is skipped to ensure data relevance.
Rule: Content older than two years relative to the current sync time will be skipped.
Incremental Refresh Behavior
After the initial full ingestion, subsequent data stream refreshes use incremental sync.
Only content created or modified since the last successful sync is processed.
Deleted content in Confluence is automatically removed from the UDLO during incremental refresh.
Handling of Skipped Content (UDLO Reporting)
When content fails any constraint check (format, size, or content age), it is skipped. The outcome is recorded in the UDLO.
Field
Value
Description
Sync Status
SUCCESS, FAILURE, or SKIPPED
Indicates the content ingestion status.
Sync Status Detail
Detailed message
Provides the reason the content was skipped.
Ingestion Size Limits and Timeout
Confluence Unstructured supports ingestion of spaces up to 500 GB per ingestion job.
Data stream refreshes that exceed 24 hours will time out. Plan ingestion jobs accordingly, especially for large spaces. If you encounter timeout failures, consider splitting content across multiple UDLOs by space to reduce per-job ingestion volume.
Troubleshooting
Connection Test Fails
Verify the Cloud ID is correct by navigating to https://<your-domain>.atlassian.net/_edge/tenant_info.
Verify the Named Credential authentication was completed successfully by re-authenticating with the Confluence 3LO provider.
Verify the Admin API Token is valid and has not expired.
Verify the Org ID matches the organization associated with your Confluence instance.
No Data Ingested / Records Not Appearing in DLO
If after a successful sync no records appear in the Data Lake Object:
Verify the Space ID is correct. The Space ID is case-sensitive (for example, ENG not eng). Check the URL: https://<domain>.atlassian.net/wiki/spaces/<SPACE_ID>/overview.
Verify content exists in the space. Empty spaces or spaces containing only restricted content will result in zero records.
Verify the authenticated user has read access to all content in the space, including restricted pages and blog posts.
Check content age. If all content in the space was last modified more than two years ago, all items are skipped due to the content age rule.
Check the UDLO Sync Status Detail field for individual record failure reasons.
Verify the Data Stream completed successfully. Navigate to the Data Stream and check for connector exceptions or partial failures.
For attachments: Verify the attached files use supported MIME types and are within size limits.
Partial Data Ingested
Large spaces may require additional sync cycles due to API rate limits.
Verify the authenticated user has permission to access all content in the space, including restricted pages.
Check the UDLO for skipped records. Some content may have been excluded due to file size, format, or content age rules.
If pages were recently updated but not appearing, wait for the next incremental sync cycle to complete.
