Properties

This is a legacy parameter. Use ProjectionExpression instead. For more information, see AttributesToGet in the Amazon DynamoDB Developer Guide.

conditionalOperator

var conditionalOperator: ConditionalOperator?

This is a legacy parameter. Use FilterExpression instead. For more information, see ConditionalOperator in the Amazon DynamoDB Developer Guide.

consistentRead

var consistentRead: Boolean?

Determines the read consistency model: If set to true, then the operation uses strongly consistent reads; otherwise, the operation uses eventually consistent reads.

exclusiveStartKey

var exclusiveStartKey: Map<String, AttributeValue>?

The primary key of the first item that this operation will evaluate. Use the value that was returned for LastEvaluatedKey in the previous operation.

expressionAttributeNames

var expressionAttributeNames: Map<String, String>?

One or more substitution tokens for attribute names in an expression. The following are some use cases for using ExpressionAttributeNames:

expressionAttributeValues

var expressionAttributeValues: Map<String, AttributeValue>?

One or more values that can be substituted in an expression.

filterExpression

var filterExpression: String?

A string that contains conditions that DynamoDB applies after the Query operation, but before the data is returned to you. Items that do not satisfy the FilterExpression criteria are not returned.

indexName

var indexName: String?

The name of an index to query. This index can be any local secondary index or global secondary index on the table. Note that if you use the IndexName parameter, you must also provide TableName.

keyConditionExpression

var keyConditionExpression: String?

The condition that specifies the key values for items to be retrieved by the Query action.

keyConditions

var keyConditions: Map<String, Condition>?

This is a legacy parameter. Use KeyConditionExpression instead. For more information, see KeyConditions in the Amazon DynamoDB Developer Guide.

limit

var limit: Int?

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 dataset 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. For more information, see Query and Scan in the Amazon DynamoDB Developer Guide.

projectionExpression

var projectionExpression: String?

A string that identifies one or more attributes to retrieve from the table. These attributes can include scalars, sets, or elements of a JSON document. The attributes in the expression must be separated by commas.

queryFilter

var queryFilter: Map<String, Condition>?

This is a legacy parameter. Use FilterExpression instead. For more information, see QueryFilter in the Amazon DynamoDB Developer Guide.

returnConsumedCapacity

var returnConsumedCapacity: ReturnConsumedCapacity?

Determines the level of detail about either provisioned or on-demand throughput consumption that is returned in the response:

scanIndexForward

var scanIndexForward: Boolean?

Specifies the order for index traversal: If true (default), the traversal is performed in ascending order; if false, the traversal is performed in descending order.

select

var select: Select?

The attributes to be returned in the result. You can retrieve all item attributes, specific item attributes, the count of matching items, or in the case of an index, some or all of the attributes projected into the index.

tableName

var tableName: String?

The name of the table containing the requested items. You can also provide the Amazon Resource Name (ARN) of the table in this parameter.
