Limitations and Troubleshooting¶
Alation Cloud Service Applies to Alation Cloud Service instances of Alation
Customer Managed Applies to customer-managed instances of Alation
Core Connector Core connectors are included with all Alation platform tiers (subject to each tier’s connector limits) and are fully supported by Alation.
Troubleshooting¶
Refer to Log Collection.
Limitations¶
- Qlik Cloud API Usage
The connector uses the Qlik Cloud API to catalog data sources (QVDs, files, and datasets) and to establish their lineage relationships with tables and table columns. The connector does not use this API to catalog Qlik Cloud as a primary BI source.
- Cross-System Lineage Not Supported
The connector does not currently support cross-system lineage due to Engine and Cloud Lineage API limitations.
- Column Name Mapping
Some sheet columns may map to multiple table columns when identical column names exist across different tables. Qlik Sense combines values for all fields with the same name, so lineage will be represented in one-to-many mapping
- Incomplete Representation of Transformation Logic
The lineage does not fully reflect certain Qlik transformation logic due to:
Limitations in the available Engine or Cloud APIs.
Missing or incomplete field-level mapping details from Qlik Sense in specific scenarios.
- Reduced Lineage When Cloud Lineage Is Disabled
When Cloud Lineage is disabled, data source (QVD, file, and dataset) to table mappings are not created. In this mode, data sources are cataloged from the Engine API response, which results in reduced lineage information.
- Master Items Not Linked
Master items do not link to their upstream sources or tables.
