The data type of the specified value must match the existing value's data type.</p> <p>If a <i>set</i> of values is specified, then those values are subtracted from the old set. For example, if the attribute value was the set <code>[a,b,c]</code> and the <code>DELETE</code> action specified <code>[a,c]</code>, then the final attribute value would be <code>[b]</code>. Specifying an empty set is an error.</p> </li> <li> <p> <code>ADD</code> - If the attribute does not already exist, then the attribute and its values are added to the item. 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 the <code>Value</code> is mathematically added to the existing attribute.

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

For example, suppose that the item you want to update doesn't have an attribute named <i>itemcount</i>, but you decide to <code>ADD</code> the number <code>3</code> to this attribute anyway. DynamoDB will create the <i>itemcount</i> 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 existing data type is a set of strings, the <code>Value</code> must also be a set of strings.</p> </li> </ul> <important> <p>The <code>ADD</code> action only supports Number and set data types. In addition, <code>ADD</code> can only be used on top-level attributes, not nested attributes.</p> </important> </li> <li> <p> <code>DELETE</code> - Deletes an element from a set.</p> <p>If a set of values is specified, then those values are subtracted from the old set. 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>.

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

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> <p>Note that if <i>none</i> of the items can be processed due to insufficient provisioned throughput on all of the tables in the request, then <code>BatchWriteItem</code> will return a <code>ProvisionedThroughputExceededException</code>.</p> <important> <p>If DynamoDB returns any unprocessed items, you should retry the batch operation on those items.

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.

Also, there are per-table limits that apply when you create a table there. For more information, see <a href="http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Limits.html">Limits</a> page in the <i>Amazon DynamoDB Developer Guide</i>.</p> <p>Although you can increase these limits by filing a case at <a href="https://console.aws.amazon.com/support/home#/">AWS Support Center</a>, obtaining the increase is not instantaneous. The <code>DescribeLimits</code> action lets you write code to compare the capacity you are currently using to those limits imposed by your account so that you have enough time to apply for an increase before you hit a limit.</p> <p>For example, you could use one of the AWS SDKs to do the following:</p> <ol> <li> <p>Call <code>DescribeLimits</code> for a particular region to obtain your current account limits on provisioned capacity there.</p> </li> <li> <p>Create a variable to hold the aggregate read capacity units provisioned for all your tables in that region, and one to hold the aggregate write capacity units.

They restrict the sum of the provisioned capacity of the new table itself and all its global secondary indexes.</p> <p>For existing tables and their GSIs, DynamoDB will not let you increase provisioned capacity extremely rapidly, but the only upper limit that applies is that the aggregate provisioned capacity over all your tables and GSIs cannot exceed either of the per-account limits.</p> <note> <p> <code>DescribeLimits</code> should only be called periodically.

You can return the item's attribute values in the same operation, using the <code>ReturnValues</code> parameter.</p> <important> <p>This topic provides general information about the <code>PutItem</code> API.</p> <p>For information on how to call the <code>PutItem</code> API using the AWS SDK in specific languages, see the following:</p> <ul> <li> <p> <a href="http://docs.aws.amazon.com/goto/aws-cli/dynamodb-2012-08-10/PutItem"> PutItem in the AWS Command Line Interface </a> </p> </li> <li> <p> <a href="http://docs.aws.amazon.com/goto/DotNetSDKV3/dynamodb-2012-08-10/PutItem"> PutItem in the AWS SDK for .NET </a> </p> </li> <li> <p> <a href="http://docs.aws.amazon.com/goto/SdkForCpp/dynamodb-2012-08-10/PutItem"> PutItem in the AWS SDK for C++ </a> </p> </li> <li> <p> <a href="http://docs.aws.amazon.com/goto/SdkForGoV1/dynamodb-2012-08-10/PutItem"> PutItem in the AWS SDK for Go </a> </p> </li> <li> <p> <a href="http://docs.aws.amazon.com/goto/SdkForJava/dynamodb-2012-08-10/PutItem"> PutItem in the AWS SDK for Java </a> </p> </li> <li> <p> <a href="http://docs.aws.amazon.com/goto/AWSJavaScriptSDK/dynamodb-2012-08-10/PutItem"> PutItem in the AWS SDK for JavaScript </a> </p> </li> <li> <p> <a href="http://docs.aws.amazon.com/goto/SdkForPHPV3/dynamodb-2012-08-10/PutItem"> PutItem in the AWS SDK for PHP V3 </a> </p> </li> <li> <p> <a href="http://docs.aws.amazon.com/goto/boto3/dynamodb-2012-08-10/PutItem"> PutItem in the AWS SDK for Python </a> </p> </li> <li> <p> <a href="http://docs.aws.amazon.com/goto/SdkForRubyV2/dynamodb-2012-08-10/PutItem"> PutItem in the AWS SDK for Ruby V2 </a> </p> </li> </ul> </important> <p>When you add an item, the primary key attribute(s) are the only required attributes.

You can optionally narrow the scope of the <code>Query</code> operation by specifying a sort key value and a comparison operator in <code>KeyConditionExpression</code>. To further refine the <code>Query</code> results, you can optionally provide a <code>FilterExpression</code>. A <code>FilterExpression</code> determines which items within the results should be returned to you. All of the other results are discarded. </p> <p> A <code>Query</code> operation always returns a result set. If no matching items are found, the result set will be empty. Queries that do not return results consume the minimum number of read capacity units for that type of read operation. </p> <note> <p> DynamoDB calculates the number of read capacity units consumed based on item size, not on the amount of data that is returned to an application. The number of capacity units consumed will be the same whether you request all of the attributes (the default behavior) or just some of them (using a projection expression). The number will also be the same whether or not you use a <code>FilterExpression</code>. </p> </note> <p> <code>Query</code> results are always sorted by the sort key value. If the data type of the sort key is Number, the results are returned in numeric order; otherwise, the results are returned in order of UTF-8 bytes. By default, the sort order is ascending. To reverse the order, set the <code>ScanIndexForward</code> parameter to false. </p> <p> A single <code>Query</code> operation will read up to the maximum number of items set (if using the <code>Limit</code> parameter) or a maximum of 1 MB of data and then apply any filtering to the results using <code>FilterExpression</code>.

A <code>FilterExpression</code> cannot contain partition key or sort key attributes. You need to specify those attributes in the <code>KeyConditionExpression</code>. </p> <note> <p> A <code>Query</code> operation can return an empty result set and a <code>LastEvaluatedKey</code> if all the items read for the page of results are filtered out. </p> </note> <p>You can query a table, a local secondary index, or a global secondary index. For a query on a table or on a local secondary index, you can set the <code>ConsistentRead</code> parameter to <code>true</code> and obtain a strongly consistent result.
