Class RecordDeaggregator

java.lang.Object

com.amazonaws.kinesis.deagg.RecordDeaggregator

public class RecordDeaggregator
extends Object

A Kinesis deaggregator convenience class. This class contains a number of static methods that provide different interfaces for deaggregating user records from an existing aggregated Kinesis record. This class is oriented towards deaggregating Kinesis records as provided by AWS Lambda (for other applications, record deaggregation is handled transparently by the Kinesis Consumer Library). NOTE: Any non-aggregated records passed to any deaggregation methods will be returned unchanged.
