Class SingleRowScanInterpreter

java.lang.Object

com.amazon.titan.diskstorage.dynamodb.iterator.SingleRowScanInterpreter

All Implemented Interfaces:

ScanContextInterpreter

public class SingleRowScanInterpreter
extends java.lang.Object
implements ScanContextInterpreter

Turns Scan results into RecordIterators for stores using the SINGLE data model. This interpreter doesn't need to consider whether or not a scan is segmented, because each item in a ScanResult represents ALL columns for a given key. It is impossible for keys to be split across multiple ScanResults (or segments for that matter) when using the SINGLE data model.
