# Identifier labels

​Several statements are tagged with an identifier label for troubleshooting 'problem queries' and identifying possible ways to optimize database settings. The addition of labels to ELT queries enables fine-grained workload management and workload isolation via Synapse WORKLOAD GROUPS and CLASSIFIERS.

The identifier labels are as follows:

| Table type | Tag |
| --- | --- |
| Hubs | CMPS\_HubIns |
| Satellites | CMPS\_SatIns |
| Type1 dimensions | CMPS\_<data mart name>\_DimT1\_Init/CMPS\_<data mart name>\_DimT1\_Incr |
| Type2 dimensions | CMPS\_<data mart name>\_DimT2\_Init/CMPS\_<data mart name>\_DimT2\_Incr |
| Transactional facts | CMPS\_<data mart name>\_FctTra\_Init/CMPS\_<data mart name>\_FctTra\_Incr |
| State-oriented facts | CMPS\_<data mart name>\_FctStO\_Init |
| Aggregated facts | CMPS\_<data mart name>\_FctAgg\_Init |
