# Zero Copy Data Federation Supportability

Refer to the list of supported and unsupported features of Data 360 when you use zero copy data federation.

## Supported

These features of Data 360 are supported when federating data from external sources.

- Batch data transforms
- Calculated Insights (Batch)
- Streaming Insights for related objects only
- Identity resolution
- Segmentation
- Activation
- Data Actions

    Note You can't map an external data lake object (DLO) to an Individual or a Lead data model object (DMO) that has a Data Action or Data Share associated with it.
- Batch Predictions in Bring Your Own Model (BYOM)
- Data 360 Related Lists
- Querying external DLO via Data Explorer and Query APIs
- Related lists
- Field enrichments
- Search index

    Note To use DMOs in a search index, they must be mapped from external DLOs that have acceleration or caching enabled. You can’t use DMOs that have mappings from a mix of native and external DLOs.

## Not Supported

You can’t use these features of Data 360 when federating data from external sources.

- Extending schema with formula fields or data type changes
- Changes in data types
- Data sharing of external DLOs and DMOs with an external data lake
- Rapid segmentation and activation
- Streaming data transforms
- Near real time identity resolution
- Streaming predictions in BYOM
- Changes to the source table schema (field name changes, capitalization changes)

Note At present, zero copydata federation supports a limited set of predicates for creating calculated insights and segments.

This approch allows users to treat disparate systems as a single logical system, called a federation, while maintaining the autonomy of each system.
