For example, suppose that the item you want\n                to update does not yet have an attribute named <i>itemcount</i>, but you decide to\n                  <code>ADD</code> the number <code>3</code> to this attribute anyway, even though\n                it currently does not exist. DynamoDB will create the <i>itemcount</i> attribute, set\n                its initial value to <code>0</code>, and finally add <code>3</code> to it. The\n                result will be a new <i>itemcount</i> attribute in the item, with a value of\n                  <code>3</code>.</p>\n                     </note>\n                  </li>\n                  <li>\n                     <p>If the existing data type is a set, and if the <code>Value</code> is also a set, then the\n                <code>Value</code> is added to the existing set. (This is a <i>set</i> operation, not\n              mathematical addition.) For example, if the attribute value was the set\n                <code>[1,2]</code>, and the <code>ADD</code> action specified <code>[3]</code>, then\n              the final attribute value would be <code>[1,2,3]</code>. An error occurs if an Add\n              action is specified for a set attribute and the attribute type specified does not\n              match the existing set type. </p>\n                     <p>Both sets must have the same primitive data type. For example, if the existing data\n              type is a set of strings, the <code>Value</code> must also be a set of strings. The same\n              holds true for number sets and binary sets.</p>\n                  </li>\n               </ul>\n               <p>This action is only valid for an existing attribute whose data type is number or is a\n          set. Do not use <code>ADD</code> for any other data types.</p>\n            </li>\n         </ul>\n\n         <p>\n            <b>If no item with the specified <i>Key</i> is found:</b>\n         </p>\n\n         <ul>\n            <li>\n               <p>\n                  <code>PUT</code> - DynamoDB creates a new item with the specified primary key, and then adds\n          the attribute. </p>\n            </li>\n            <li>\n               <p>\n                  <code>DELETE</code> - Nothing happens; there is no attribute to delete.</p>\n            </li>\n            <li>\n               <p>\n                  <code>ADD</code> - DynamoDB creates an item with the supplied primary key and number (or set\n          of numbers) for the attribute value.

If any\n      requested operations fail because the table's provisioned throughput is exceeded or an\n      internal processing failure occurs, the failed operations are returned in the\n        <code>UnprocessedItems</code> response parameter.

However, <i>we strongly recommend that you use an exponential backoff algorithm</i>.\n        If you retry the batch operation immediately, the underlying read or write requests can\n        still fail due to throttling on the individual tables. If you delay the batch operation\n        using exponential backoff, the individual requests in the batch are much more likely to\n        succeed.</p>\n            <p>For more information, see <a href=\"https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/ErrorHandling.html#Programming.Errors.BatchOperations\">Batch Operations and Error Handling</a> in the <i>Amazon DynamoDB\n                    Developer Guide</i>.</p>\n         </important>\n\n         <p>With <code>BatchWriteItem</code>, you can efficiently write or delete large amounts of\n            data, such as from Amazon EMR, or copy data from another database into DynamoDB. In\n            order to improve performance with these large-scale operations,\n                <code>BatchWriteItem</code> does not behave in the same way as individual\n                <code>PutItem</code> and <code>DeleteItem</code> calls would. For example, you\n            cannot specify conditions on individual put and delete requests, and\n                <code>BatchWriteItem</code> does not return deleted items in the response.</p>\n         <p>If you use a programming language that supports concurrency, you can use\n      threads to write items in parallel. Your application must include the necessary logic to\n      manage the threads. With languages that don't support threading, you must update\n      or delete the specified items one at a time. In both situations, <code>BatchWriteItem</code>\n      performs the specified put and delete operations in\n      parallel, giving you the power of the thread pool approach without having to introduce\n      complexity into your application.</p>\n         <p>Parallel processing reduces latency, but each specified put and delete request consumes the same number of write capacity units whether it is processed in parallel or not. Delete operations on nonexistent items consume one write capacity unit.</p>\n         <p>If one or more of the following is true, DynamoDB rejects the entire batch write operation:</p>\n         <ul>\n            <li>\n               <p>One or more tables specified in the <code>BatchWriteItem</code> request does not exist.</p>\n            </li>\n            <li>\n               <p>Primary key attributes specified on an item in the request do not match those in the corresponding table's primary key schema.</p>\n            </li>\n            <li>\n               <p>You try to perform multiple operations on the same item in the same <code>BatchWriteItem</code>\n          request.

Also, there are per-table quotas that apply when you\n            create a table there.

For\n                                example, suppose that the item you want to update doesn't have an\n                                attribute named <code>itemcount</code>, but you decide to\n                                    <code>ADD</code> the number <code>3</code> to this attribute\n                                anyway.

An error occurs if an <code>ADD</code>\n              action is specified for a set attribute and the attribute type specified does not\n              match the existing set type. </p>\n                     <p>Both sets must have the same primitive data type.
