Class ExtractAvroTreeBuilder

java.lang.Object

org.kitesdk.morphline.avro.ExtractAvroTreeBuilder

All Implemented Interfaces:

CommandBuilder

public final class ExtractAvroTreeBuilder
extends Object
implements CommandBuilder

Command that converts an attached Avro datum to a morphline record by recursively walking the Avro tree and extracting all data into a single morphline record, with fields named by their path in the Avro tree. The Avro input object is expected to be contained in the Fields.ATTACHMENT_BODY This kind of mapping is useful for simple Avro schemas, but a rather simplistic (and perhaps expensive) approach for complex Avro schemas.
