ScanRequest (AWS Java SDK for Amazon DynamoDB 1.9.16 API)

java.lang.Object
- com.amazonaws.AmazonWebServiceRequest
- - com.amazonaws.services.dynamodbv2.model.ScanRequest

All Implemented Interfaces:

Serializable
```
public class ScanRequest
extends com.amazonaws.AmazonWebServiceRequest
implements Serializable
```
Container for the parameters to the Scan operation.
The Scan operation returns one or more items and item attributes by accessing every item in the table. To have DynamoDB return fewer items, you can provide a ScanFilter operation.

If the total number of scanned items exceeds the maximum data set size limit of 1 MB, the scan stops and results are returned to the user as a LastEvaluatedKey value to continue the scan in a subsequent operation. The results also include the number of items exceeding the limit. A scan can result in no table data meeting the filter criteria.

The result set is eventually consistent.

By default, Scan operations proceed sequentially; however, for faster performance on large tables, applications can request a parallel Scan operation by specifying the Segment and TotalSegments parameters. For more information, see Parallel Scan in the Amazon DynamoDB Developer Guide .

  - getLimit
```
public Integer getLimit()
```
    The maximum number of items to evaluate (not necessarily the number of matching items). If DynamoDB processes the number of items up to the limit while processing the results, it stops the operation and returns the matching values up to that point, and a key in LastEvaluatedKey to apply in a subsequent operation, so that you can pick up where you left off. Also, if the processed data set size exceeds 1 MB before DynamoDB reaches this limit, it stops the operation and returns the matching values up to the limit, and a key in LastEvaluatedKey to apply in a subsequent operation to continue the operation.

  - getScanFilter
```
public Map<String,Condition> getScanFilter()
```
    There is a newer parameter available. Use FilterExpression instead. Note that if you use ScanFilter and FilterExpression at the same time, DynamoDB will return a ValidationException exception.
    This parameter does not support lists or maps.
    A condition that evaluates the scan results and returns only the desired values.
    If you specify more than one condition in the ScanFilter map, then by default all of the conditions must evaluate to true. In other words, the conditions are ANDed together. (You can use the ConditionalOperator parameter to OR the conditions instead. If you do this, then at least one of the conditions must evaluate to true, rather than all of them.)
    Each ScanFilter element consists of an attribute name to compare, along with the following:
    
    AttributeValueList - One or more values to evaluate against the supplied attribute. The number of values in the list depends on the operator specified in ComparisonOperator .
    For type Number, value comparisons are numeric.
    String value comparisons for greater than, equals, or less than are based on ASCII character code values. For example, a is greater than A, and aa is greater than B. For a list of code values, see http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters.
    For Binary, DynamoDB treats each byte of the binary data as unsigned when it compares binary values, for example when evaluating query expressions.
    For information on specifying data types in JSON, see JSON Data Format in the Amazon DynamoDB Developer Guide.
    
    ComparisonOperator - A comparator for evaluating attributes. For example, equals, greater than, less than, etc.
    The following comparison operators are available:
    EQ | NE | LE | LT | GE | GT | NOT_NULL | NULL | CONTAINS | NOT_CONTAINS | BEGINS_WITH | IN | BETWEEN
    For complete descriptions of all comparison operators, see Condition.
    Returns:
    There is a newer parameter available. Use FilterExpression instead. Note that if you use ScanFilter and FilterExpression at the same time, DynamoDB will return a ValidationException exception.
    This parameter does not support lists or maps.
    A condition that evaluates the scan results and returns only the desired values.
    If you specify more than one condition in the ScanFilter map, then by default all of the conditions must evaluate to true. In other words, the conditions are ANDed together. (You can use the ConditionalOperator parameter to OR the conditions instead. If you do this, then at least one of the conditions must evaluate to true, rather than all of them.)
    Each ScanFilter element consists of an attribute name to compare, along with the following:
    
    AttributeValueList - One or more values to evaluate against the supplied attribute. The number of values in the list depends on the operator specified in ComparisonOperator .
    For type Number, value comparisons are numeric.
    String value comparisons for greater than, equals, or less than are based on ASCII character code values. For example, a is greater than A, and aa is greater than B. For a list of code values, see http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters.

    For a parallel Scan request, TotalSegments represents the total number of segments into which the Scan operation will be divided. The value of TotalSegments corresponds to the number of application workers that will perform the parallel scan. For example, if you want to scan a table using four application threads, specify a TotalSegments value of 4.
    The value for TotalSegments must be greater than or equal to 1, and less than or equal to 1000000. If you specify a TotalSegments value of 1, the Scan operation will be sequential rather than parallel.
    If you specify TotalSegments, you must also specify Segment.
