The EDS entity types include aggregators, source service types, target service types, and transformation types. You can use built-in entity types or create and use custom entity types in data flows.
You can add the following built-in entity types to a data flow:
Source service types read data from data streams and common data file formats.
Target service types receive data from one or more source services, or aggregators, and write data to a data store.
Transformation types transform data that a source service, another transformation, or aggregator publishes, or the data that a target service, another transformation, or aggregator receives, or both.
Aggregators collect data from source services or other aggregators and publish the data to target services or other aggregators.
When you add entities to data flows, specify the entity properties. You can also use parameters to set the properties for entities. After you add the entities to the data flows, map them to node groups.
Use built-in source service types, target service types, and transformation types for common use cases. If the built-in entity types do not meet your requirements, you can create and use custom entity types.
