If the attribute does exist, then the behavior of <code>ADD</code> depends on the data type of the attribute:</p>    <ul>     <li> <p>If the existing attribute is a number, and if <code>Value</code> is also a number, then <code>Value</code> is mathematically added to the existing attribute.

For example, suppose that the item you want to update doesn't have an attribute named <code>itemcount</code>, but you decide to <code>ADD</code> the number <code>3</code> to this attribute anyway. DynamoDB will create the <code>itemcount</code> attribute, set its initial value to <code>0</code>, and finally add <code>3</code> to it.

For example, if the attribute value is the set <code>[1,2]</code>, and the <code>ADD</code> action specified <code>[3]</code>, then the final attribute value is <code>[1,2,3]</code>. An error occurs if an <code>ADD</code> action is specified for a set attribute and the attribute type specified does not match the existing set type. </p> <p>Both sets must have the same primitive data type.

For example, if the attribute value was the set <code>[a,b,c]</code> and the <code>DELETE</code> action specifies <code>[a,c]</code>, then the final attribute value is <code>[b]</code>.

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 <a href="https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/HowItWorks.NamingRulesDataTypes.html">Naming Rules and Data Types</a>.</p> <note>

If any requested operations fail because the table's provisioned throughput is exceeded or an internal processing failure occurs, the failed operations are returned in the <code>UnprocessedItems</code> response parameter. You can investigate and optionally resend the requests. Typically, you would call <code>BatchWriteItem</code> in a loop. Each iteration would check for unprocessed items and submit a new <code>BatchWriteItem</code> request with those unprocessed items until all items have been processed.</p>

If you retry the batch operation immediately, the underlying read or write requests can still fail due to throttling on the individual tables. If you delay the batch operation using exponential backoff, the individual requests in the batch are much more likely to succeed.</p>

In order to improve performance with these large-scale operations, <code>BatchWriteItem</code> does not behave in the same way as individual <code>PutItem</code> and <code>DeleteItem</code> calls would. For example, you cannot specify conditions on individual put and delete requests, and <code>BatchWriteItem</code> does not return deleted items in the response.</p>
    /// <p>If you use a programming language that supports concurrency, you can use threads to write items in parallel. Your application must include the necessary logic to manage the threads. With languages that don't support threading, you must update or delete the specified items one at a time.
