Processing Hierarchical Data in Streaming Mappings

Data objects in a streaming mapping can process hierarchical data through complex data types. If the source contains hierarchical data, you must enable the read data operation to project columns as complex data types.

The following table shows the format and complex data types that sources in a Streaming mapping support:

Format	Data Type	Amazon Kinesis Streams	Azure EventHub	JMS	Kafka	MapRStreams
Avro	Flat	Supported	Supported	Not supported	Supported	Supported
