Class MultiRowSequentialScanInterpreter

java.lang.Object

com.amazon.titan.diskstorage.dynamodb.iterator.MultiRowSequentialScanInterpreter

All Implemented Interfaces:

ScanContextInterpreter

public class MultiRowSequentialScanInterpreter
extends java.lang.Object
implements ScanContextInterpreter

Interprets Scan results for MULTI stores and assumes that results are SEQUENTIAL. This means that the scan is assumed to be non-segmented. We need this assumption because it makes it so we don't need to keep track of where segment boundaries lie in order to avoid returning duplicate hash keys.
