Input Schema

Field	Type	Required	Default	Description
organization_uuid	uuid	Yes	—	Authenticated organization UUID used for field resolution and connection scoping.
connection_uuid	uuid	Yes	—	AWS CloudConnection UUID for the target DynamoDB account, scoped to the caller organization.
workflow_run_id	string	No	—	Engine DAG run ID stamped onto child steps.
region	string	No	—	AWS API endpoint region override; omit to use the connection or SDK default.
table_name	string	Yes	—	The name of the table containing the requested items. You can also provide the Amazon Resource Name (ARN) of the table in this parameter.
index_name	string	No	—	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.
select	string	No	—	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 p...
attributes_to_get	list	No	—	This is a legacy parameter. Use ProjectionExpression instead. For more information, see AttributesToGet in the Amazon DynamoDB Developer Guide.
limit	integer	No	—	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 operatio...
consistent_read	boolean	No	—	Determines the read consistency model: If set to true, then the operation uses strongly consistent reads; otherwise, the operation uses eventually consistent reads. Strongly consistent reads are no...
key_conditions	json	No	—	This is a legacy parameter. Use KeyConditionExpression instead. For more information, see KeyConditions in the Amazon DynamoDB Developer Guide.
query_filter	json	No	—	This is a legacy parameter. Use FilterExpression instead. For more information, see QueryFilter in the Amazon DynamoDB Developer Guide.
conditional_operator	string	No	—	This is a legacy parameter. Use FilterExpression instead. For more information, see ConditionalOperator in the Amazon DynamoDB Developer Guide.
scan_index_forward	boolean	No	—	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. Items with the same partition ke...
exclusive_start_key	json	No	—	The primary key of the first item that this operation will evaluate. Use the value that was returned for LastEvaluatedKey in the previous operation. The data type for ExclusiveStartKey must be Stri...
return_consumed_capacity	string	No	—	Determines the level of detail about either provisioned or on-demand throughput consumption that is returned in the response: INDEXES - The response includes the aggregate ConsumedCapacity for the...
projection_expression	string	No	—	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 sepa...
filter_expression	string	No	—	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....
key_condition_expression	string	No	—	The condition that specifies the key values for items to be retrieved by the Query action. The condition must perform an equality test on a single partition key value. The condition can optionally...
expression_attribute_names	json	No	—	One or more substitution tokens for attribute names in an expression. The following are some use cases for using ExpressionAttributeNames: To access an attribute whose name conflicts with a DynamoD...
expression_attribute_values	json	No	—	One or more values that can be substituted in an expression. Use the : (colon) character in an expression to dereference an attribute value. For example, suppose that you wanted to check whether th...
provider_native_request	json	No	—	Optional provider-native request overrides for AWS parameters not yet promoted to first-class fields.
