Struct rusoto_dynamodb::BatchWriteItemOutput

pub struct BatchWriteItemOutput {
    pub consumed_capacity: Option<Vec<ConsumedCapacity>>,
    pub item_collection_metrics: Option<HashMap<String, Vec<ItemCollectionMetrics>>>,
    pub unprocessed_items: Option<HashMap<String, Vec<WriteRequest>>>,
}

Represents the output of a BatchWriteItem operation.

Fields

consumed_capacity: Option<Vec<ConsumedCapacity>>

The capacity units consumed by the entire BatchWriteItem operation.

Each element consists of:

• TableName - The table that consumed the provisioned throughput.

• CapacityUnits - The total number of capacity units consumed.

item_collection_metrics: Option<HashMap<String, Vec<ItemCollectionMetrics>>>

A list of tables that were processed by BatchWriteItem and, for each table, information about any item collections that were affected by individual DeleteItem or PutItem operations.

Each entry consists of the following subelements:

• ItemCollectionKey - The partition key value of the item collection. This is the same as the partition key value of the item.

• SizeEstimateRangeGB - An estimate of item collection size, expressed in GB. This is a two-element array containing a lower bound and an upper bound for the estimate. The estimate includes the size of all the items in the table, plus the size of all attributes projected into all of the local secondary indexes on the table. Use this estimate to measure whether a local secondary index is approaching its size limit.

  The estimate is subject to change over time; therefore, do not rely on the precision or accuracy of the estimate.

unprocessed_items: Option<HashMap<String, Vec<WriteRequest>>>

A map of tables and requests against those tables that were not processed. The UnprocessedItems value is in the same form as RequestItems, so you can provide this value directly to a subsequent BatchGetItem operation. For more information, see RequestItems in the Request Parameters section.

Each UnprocessedItems entry consists of a table name and, for that table, a list of operations to perform (DeleteRequest or PutRequest).

• DeleteRequest - Perform a DeleteItem operation on the specified item. The item to be deleted is identified by a Key subelement:

  • Key - A map of primary key attribute values that uniquely identify the item. Each entry in this map consists of an attribute name and an attribute value.

• PutRequest - Perform a PutItem operation on the specified item. The item to be put is identified by an Item subelement:

  • Item - A map of attributes and their values. Each entry in this map consists of an attribute name and an attribute value. Attribute values must not be null; string and binary type attributes must have lengths greater than zero; and set type attributes must not be empty. Requests that contain empty values will be rejected with a ValidationException exception.

    If you specify any attributes that are part of an index key, then the data types for those attributes must match those of the schema in the table's attribute definition.

If there are no unprocessed items remaining, the response contains an empty UnprocessedItems map.
