If the attribute\n already exists, it is replaced by the new value. </p>\n </li>\n <li>\n <p>\n <code>DELETE</code> - If no value is specified, the attribute and its value are\n removed from the item. The data type of the specified value must match the\n existing value's data type.</p>\n <p>If a <i>set</i> of values is specified, then those values are\n subtracted from the old set. For example, if the attribute value was the set\n <code>[a,b,c]</code> and the <code>DELETE</code> action specified\n <code>[a,c]</code>, then the final attribute value would be\n <code>[b]</code>. Specifying an empty set is an error.</p>\n </li>\n <li>\n <p>\n <code>ADD</code> - If the attribute does not already exist, then the attribute\n and its values are added to the item. If the attribute does exist, then the\n behavior of <code>ADD</code> depends on the data type of the attribute:</p>\n <ul>\n <li>\n <p>If the existing attribute is a number, and if <code>Value</code> is\n also a number, then the <code>Value</code> is mathematically added to\n the existing attribute. If <code>Value</code> is a negative number, then\n it is subtracted from the existing attribute.</p>\n <note>\n <p> If you use <code>ADD</code> to increment or decrement a number\n value for an item that doesn't exist before the update, DynamoDB\n uses 0 as the initial value.</p>\n <p>In addition, if you use <code>ADD</code> to update an existing\n item, and intend to increment or decrement an attribute value which\n does not yet exist, DynamoDB uses <code>0</code> as the initial\n value. For example, suppose that the item you want to update does\n not yet have an attribute named <i>itemcount</i>, but\n you decide to <code>ADD</code> the number <code>3</code> to this\n attribute anyway, even though it currently does not exist. DynamoDB\n will create the <i>itemcount</i> attribute, set its\n initial value to <code>0</code>, and finally add <code>3</code> to\n it. The result will be a new <i>itemcount</i>\n attribute in the item, with a value of <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\n also a set, then the <code>Value</code> is added to the existing set.\n (This is a <i>set</i> operation, not mathematical\n addition.) For example, if the attribute value was the set\n <code>[1,2]</code>, and the <code>ADD</code> action specified\n <code>[3]</code>, then the final attribute value would be\n <code>[1,2,3]</code>. An error occurs if an Add action is specified\n for a set attribute and the attribute type specified does not match the\n existing set type. </p>\n <p>Both sets must have the same primitive data type. For example, if the\n existing data type is a set of strings, the <code>Value</code> must also\n be a set of strings. The same holds true for number sets and binary\n sets.</p>\n </li>\n </ul>\n <p>This action is only valid for an existing attribute whose data type is number\n or is a set. Do not use <code>ADD</code> for any other data types.</p>\n </li>\n </ul>\n <p>\n <b>If no item with the specified <i>Key</i> is\n found:</b>\n </p>\n <ul>\n <li>\n <p>\n <code>PUT</code> - DynamoDB creates a new item with the specified primary key,\n and then adds 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 a new item with the supplied primary key and\n number (or set) for the attribute value.

You identify requested items by primary key.</p>\n <p>A single operation can retrieve up to 16 MB of data, which can contain as many as 100\n items. <code>BatchGetItem</code> returns a partial result if the response size limit is\n exceeded, the table's provisioned throughput is exceeded, more than 1MB per partition is requested,\n or an internal processing failure occurs. If a partial result is returned, the operation returns a value for\n <code>UnprocessedKeys</code>. You can use this value to retry the operation starting\n with the next item to get.</p>\n <important>\n <p>If you request more than 100 items, <code>BatchGetItem</code> returns a\n <code>ValidationException</code> with the message \"Too many items requested for\n the BatchGetItem call.\"</p>\n </important>\n <p>For example, if you ask to retrieve 100 items, but each individual item is 300 KB in\n size, the system returns 52 items (so as not to exceed the 16 MB limit). It also returns\n an appropriate <code>UnprocessedKeys</code> value so you can get the next page of\n results. If desired, your application can include its own logic to assemble the pages of\n results into one dataset.</p>\n <p>If <i>none</i> of the items can be processed due to insufficient\n provisioned throughput on all of the tables in the request, then\n <code>BatchGetItem</code> returns a\n <code>ProvisionedThroughputExceededException</code>. If <i>at least\n one</i> of the items is successfully processed, then\n <code>BatchGetItem</code> completes successfully, while returning the keys of the\n unread items in <code>UnprocessedKeys</code>.</p>\n <important>\n <p>If DynamoDB returns any unprocessed items, you should retry the batch operation on\n those items. However, <i>we strongly recommend that you use an exponential\n backoff algorithm</i>. If you retry the batch operation immediately, the\n underlying read or write requests can still fail due to throttling on the individual\n tables. If you delay the batch operation using exponential backoff, the individual\n requests in the batch are much more likely to succeed.</p>\n <p>For more information, see <a href=\"https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/ErrorHandling.html#BatchOperations\">Batch Operations and Error Handling</a> in the <i>Amazon DynamoDB\n Developer Guide</i>.</p>\n </important>\n <p>By default, <code>BatchGetItem</code> performs eventually consistent reads on every\n table in the request. If you want strongly consistent reads instead, you can set\n <code>ConsistentRead</code> to <code>true</code> for any or all tables.</p>\n <p>In order to minimize response latency, <code>BatchGetItem</code> may retrieve items in\n parallel.</p>\n <p>When designing your application, keep in mind that DynamoDB does not return items in\n any particular order. To help parse the response by item, include the primary key values\n for the items in your request in the <code>ProjectionExpression</code> parameter.</p>\n <p>If a requested item does not exist, it is not returned in the result. Requests for\n nonexistent items consume the minimum read capacity units according to the type of read.\n For more information, see <a href=\"https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/WorkingWithTables.html#CapacityUnitCalculations\">Working with Tables</a> in the <i>Amazon DynamoDB Developer\n Guide</i>.</p>",
