Changing Level Control and load logs
Changing Level Control for sources and entities
The default metadata management level for all new sources can be set for Qlik Catalog in the Administration module System Settings tab. For more information, see System Settings: Level Control.
Additionally, there are three places in the source module where the level is set or can be modified:
- When adding a new source set a Default Entity Level;
- When adding new entities to an existing source, set the Entity Level for new entities;
- In the source and entity grids, select one or more objects then click Change Level and select a metadata control level.
Level Control and load logs
If Level Control has been enabled in the environment (Administration: System Settings) allowing for Registered and Addressed entities, load logs become important for understanding what kind of data, metadata, and statistics are available for sources per Load Type. Load logs detail the level changes that occur under the following circumstances.
Load logs for a data entity have column Load Type that corresponds with Default Level in source.
|
Load Type |
Default Level |
|---|---|
|
DATA |
The data was loaded as a Managed entity and all good | bad | ugly | profile | sample | log data are available. |
|
STATISTICS |
The data was loaded as a Registered entity and only profile | sample |log data are available. |
|
METADATA |
Metadata was refreshed as an Addressed entity. No data is available in the file system or distribution tables. |
|
STALE |
The load log is no longer valid and no data is available. The log becomes stale when the entity has been demoted from Registered or Managed to Addressed. The load cannot be used in prepare or publish and deleting data (file system and distribution tables) is not a valid action for this load type. |
Load Type can change for a Load Log under these circumstances:
|
Action |
Load Behavior |
|
Managed entity is demoted to Registered |
Load logs with load type DATA are updated to load type STATISTICS, so only sample and profile data are available for that partition. The original load type is still available in the load log details.
|
|
Managed or Registered entity is demoted to Addressed |
Load logs with load type DATA/STATISTICS are updated to load type STALE and no data is available for that partition. The original load type is still available in the load log details.
|
|
Upon deletion of objects, if a user selects Delete File System Data data and/or Drop Table Structure from options but keeps the object (Entity) (does not Delete Entity). |
Load logs for entities are updated to load type STALE and no data is available for the affected partitions. The original load type is still available in the load log details.
