What could cause some identities to be excluded from the dataflow run?

When considering the potential reasons for some identities being excluded from a dataflow run, the scenario in which some identities were not recognized by the destination is a valid and common issue. In data management and integrations within Adobe Experience Platform, it is crucial for the identities to be recognized by the destination system in order for the data containing those identities to be successfully processed and utilized.

If a destination cannot recognize certain identities, possibly due to schema mismatches, incompatible formats, or simply because the destination does not support those particular identity types, those identities will be excluded from the dataflow. This ensures that only relevant and recognizable data is sent to the destination, maintaining data integrity and ensuring that the downstream systems can properly utilize the information.

Recognizing identities is fundamental to the overall operation of data flows, as it directly impacts how data is managed and represented in different environments. Thus, the inability for some identities to be recognized by the destination becomes a crucial factor that leads to their exclusion from the dataflow run.
