The batch_write_item
operation puts or deletes multiple items in one or more tables. A single call to batch_write_item
can transmit up to 16MB of data over the network, consisting of up to 25 item put or delete operations. While individual items can be up to 400 KB once stored, it's important to note that an item's representation might be greater than 400KB while being sent in DynamoDB's JSON format for the API call. For more details on this distinction, see Naming Rules and Data Types.

dynamodb_batch_write_item(
RequestItems,
ReturnConsumedCapacity = NULL,
ReturnItemCollectionMetrics = NULL
)
[required] A map of one or more table names or table ARNs and, for each table, a
list of operations to be performed (DeleteRequest
or PutRequest
).
Each element in the map consists of the following:
DeleteRequest
- Perform a delete_item
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. For each primary key, you
must provide all of the key attributes. For example, with a
simple primary key, you only need to provide a value for the
partition key. For a composite primary key, you must provide
values for both the partition key and the sort key.
PutRequest
- Perform a put_item
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
are 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.
Determines whether item collection metrics are returned. If set to
SIZE
, the response includes statistics about item collections, if any,
that were modified during the operation are returned in the response. If
set to NONE
(the default), no statistics are returned.
