Class StreamFormatter

java.lang.Object

co.cask.cdap.etl.api.Transform<co.cask.cdap.api.data.format.StructuredRecord,co.cask.cdap.api.data.format.StructuredRecord>

co.cask.hydrator.plugin.StreamFormatter

All Implemented Interfaces:

co.cask.cdap.etl.api.Destroyable, co.cask.cdap.etl.api.PipelineConfigurable, co.cask.cdap.etl.api.StageLifecycle<co.cask.cdap.etl.api.TransformContext>, co.cask.cdap.etl.api.Transformation<co.cask.cdap.api.data.format.StructuredRecord,co.cask.cdap.api.data.format.StructuredRecord>

public final class StreamFormatter
extends co.cask.cdap.etl.api.Transform<co.cask.cdap.api.data.format.StructuredRecord,co.cask.cdap.api.data.format.StructuredRecord>

Transforms a StructuredRecord into co.cask.cdap.api.flow.flowlet.StreamEvent. This transforms formats the structured into a StreamEvent. It allows one to specify the fields that need to be considered as HEADER and for BODY one can specify the format as CSV, TSV, PSV and JSON.
