Expand description
Represents the output of a BatchGetItem
operation.
Fields (Non-exhaustive)
This struct is marked as non-exhaustive
Struct { .. }
syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.responses: Option<HashMap<String, Vec<HashMap<String, AttributeValue>>>>
A map of table name to a list of items. Each object in Responses
consists of a table
name, along with a map of attribute data consisting of the data type and attribute value.
unprocessed_keys: Option<HashMap<String, KeysAndAttributes>>
A map of tables and their respective keys that were not processed with the current response.
The UnprocessedKeys
value is in the same form as RequestItems
, so the value can
be provided directly to a subsequent BatchGetItem
operation. For more information, see
RequestItems
in the Request Parameters section.
Each element consists of:
-
Keys
- An array of primary key attribute values that define specific items in the table. -
ProjectionExpression
- One or more attributes to be retrieved from the table or index. By default, all attributes are returned. If a requested attribute is not found, it does not appear in the result. -
ConsistentRead
- The consistency of a read operation. If set totrue
, then a strongly consistent read is used; otherwise, an eventually consistent read is used.
If there are no unprocessed keys remaining, the response contains an empty
UnprocessedKeys
map.
consumed_capacity: Option<Vec<ConsumedCapacity>>
The read capacity units consumed by the entire BatchGetItem
operation.
Each element consists of:
-
TableName
- The table that consumed the provisioned throughput. -
CapacityUnits
- The total number of capacity units consumed.
