Retrieves one or more items and its attributes by performing a full scan of a table.

Provide a ScanFilter to get more specific results.

com.amazonaws.services.dynamodbv2.model.ScanRequest
aws.amazon.com/amazondynamodb/latest/developerguide/QueryAndScan.html#QueryAndScanParallelScan"> Parallel Scan in the Amazon DynamoDB Developer Guide.

org.apache.commons.weaver.model.ScanRequest
Scan request object describing the types of elements in which a given {@link Weaver} or {@link Cleaner} isinterested.
org.apache.hadoop.hbase.hbql.statement.select.ScanRequest
org.apache.hadoop.hbase.protobuf.generated.ClientProtos.ScanRequest
org.apache.hedwig.server.persistence.ScanRequest
Encapsulates a request for reading a single message. The message on the given topic at the given seqId is scanned. A call-back {@link ScanCallback}is provided. When the message is scanned, the {@link ScanCallback#messageScanned(Object,Message)} method is called. Sincethere is only 1 record to be scanned the {@link ScanCallback#operationFinished(Object)} method may not be called sinceits redundant. {@link ScanCallback#scanFailed(Object,org.apache.hedwig.exceptions.PubSubException)}method is called in case of error.
