* The BatchGetItem operation returns the attributes of one or more items from one or more tables. You
* identify requested items by primary key.
*
*
* A single operation can retrieve up to 16 MB of data, which can contain as many as 100 items.
* BatchGetItem 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 UnprocessedKeys. You can use this value to retry the operation
* starting with the next item to get.
*
*
*
* If you request more than 100 items BatchGetItem will return a ValidationException with
* the message "Too many items requested for the BatchGetItem call".
*
*
*
* 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 UnprocessedKeys 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.
*
*
* If none of the items can be processed due to insufficient provisioned throughput on all of the tables in
* the request, then BatchGetItem will return a ProvisionedThroughputExceededException. If
* at least one of the items is successfully processed, then BatchGetItem completes
* successfully, while returning the keys of the unread items in UnprocessedKeys.
*
*
*
* If DynamoDB returns any unprocessed items, you should retry the batch operation on those items. However, we
* strongly recommend that you use an exponential backoff algorithm. 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.
*
*
* For more information, see Batch
* Operations and Error Handling in the Amazon DynamoDB Developer Guide.
*
*
*
* By default, BatchGetItem performs eventually consistent reads on every table in the request. If you
* want strongly consistent reads instead, you can set ConsistentRead to true for any or
* all tables.
*
*
* In order to minimize response latency, BatchGetItem retrieves items in parallel.
*
*
* 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
* ProjectionExpression parameter.
*
*
* 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. For more information, see Capacity Units Calculations in the Amazon DynamoDB Developer Guide.
*
*
* @param batchGetItemRequest
* Represents the input of a BatchGetItem operation.
* @return A Java Future containing the result of the BatchGetItem operation returned by the service.
* The CompletableFuture returned by this method can be completed exceptionally with the following
* exceptions.
*
* - ProvisionedThroughputExceededException Your request rate is too high. The AWS SDKs for DynamoDB
* automatically retry requests that receive this exception. Your request is eventually successful, unless
* your retry queue is too large to finish. Reduce the frequency of requests and use exponential backoff.
* For more information, go to Error Retries and Exponential Backoff in the Amazon DynamoDB Developer Guide.
* - ResourceNotFoundException The operation tried to access a nonexistent table or index. The resource

* This is a variant of {@link #batchGetItem(software.amazon.awssdk.services.dynamodb.model.BatchGetItemRequest)}
* operation. The return type is a custom publisher that can be subscribed to request a stream of response pages.
* SDK will internally handle making service calls for you.
*
*
* When the operation is called, an instance of this class is returned. At this point, no service calls are made yet
* and so there is no guarantee that the request is valid. If there are errors in your request, you will see the
* failures only after you start streaming the data. The subscribe method should be called as a request to start
* streaming data. For more info, see
* {@link org.reactivestreams.Publisher#subscribe(org.reactivestreams.Subscriber)}. Each call to the subscribe
* method will result in a new {@link org.reactivestreams.Subscription} i.e., a new contract to stream data from the
* starting request.
*
*
*
* The following are few ways to use the response class:
*
* 1) Using the forEach helper method
*
*
* {@code
* software.amazon.awssdk.services.dynamodb.paginators.BatchGetItemPublisher publisher = client.batchGetItemPaginator(request);
* CompletableFuture future = publisher.forEach(res -> { // Do something with the response });
* future.get();
* }
*
*
* 2) Using a custom subscriber
*
*
* {@code
* software.amazon.awssdk.services.dynamodb.paginators.BatchGetItemPublisher publisher = client.batchGetItemPaginator(request);
* publisher.subscribe(new Subscriber() {
*
* public void onSubscribe(org.reactivestreams.Subscriber subscription) { //... };
*
*
* public void onNext(software.amazon.awssdk.services.dynamodb.model.BatchGetItemResponse response) { //... };
* });}
*
*
* As the response is a publisher, it can work well with third party reactive streams implementations like RxJava2.
*
* Note: If you prefer to have control on service calls, use the
* {@link #batchGetItem(software.amazon.awssdk.services.dynamodb.model.BatchGetItemRequest)} operation.
*
*
* @param batchGetItemRequest
* Represents the input of a BatchGetItem operation.
* @return A custom publisher that can be subscribed to request a stream of response pages.
* The CompletableFuture returned by this method can be completed exceptionally with the following

*
* The BatchWriteItem operation puts or deletes multiple items in one or more tables. A single call to
* BatchWriteItem can write up to 16 MB of data, which can comprise as many as 25 put or delete
* requests. Individual items to be written can be as large as 400 KB.
*
*
*
* BatchWriteItem cannot update items. To update items, use the UpdateItem action.
*
*
*
* The individual PutItem and DeleteItem operations specified in
* BatchWriteItem are atomic; however BatchWriteItem as a whole is not. 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 UnprocessedItems response parameter. You can investigate
* and optionally resend the requests. Typically, you would call BatchWriteItem in a loop. Each
* iteration would check for unprocessed items and submit a new BatchWriteItem request with those
* unprocessed items until all items have been processed.
*
*
* Note that if none of the items can be processed due to insufficient provisioned throughput on all of the
* tables in the request, then BatchWriteItem will return a
* ProvisionedThroughputExceededException.
*
*
*
* If DynamoDB returns any unprocessed items, you should retry the batch operation on those items. However, we
* strongly recommend that you use an exponential backoff algorithm. 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.
*
*
* For more information, see Batch
* Operations and Error Handling in the Amazon DynamoDB Developer Guide.
*
*
*
* With BatchWriteItem, you can efficiently write or delete large amounts of data, such as from Amazon
* Elastic MapReduce (EMR), or copy data from another database into DynamoDB. In order to improve performance with
* these large-scale operations, BatchWriteItem does not behave in the same way as individual
* PutItem and DeleteItem calls would. For example, you cannot specify conditions on
* individual put and delete requests, and BatchWriteItem does not return deleted items in the
* response.
*
*
* 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. In both situations, BatchWriteItem
* performs the specified put and delete operations in parallel, giving you the power of the thread pool approach
* without having to introduce complexity into your application.
*
*
* 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.
*
*
* If one or more of the following is true, DynamoDB rejects the entire batch write operation:
*
*
* -
*
* One or more tables specified in the BatchWriteItem request does not exist.
*
*
* -
*
* Primary key attributes specified on an item in the request do not match those in the corresponding table's
* primary key schema.
*
*
* -

* before you hit a limit.
*

* -
*
* Call DescribeLimits for a particular region to obtain your current account limits on provisioned
* capacity there.
*
*
* -
*
* 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. Zero them both.
*
*
* -
*
* Call ListTables to obtain a list of all your DynamoDB tables.

* -
*
* For each table name listed by ListTables, do the following:
*
*
* -
*
* Call DescribeTable with the table name.
*
*
* -
*
* Use the data returned by DescribeTable to add the read capacity units and write capacity units
* provisioned for the table itself to your variables.
*
*

*
* If the table has one or more global secondary indexes (GSIs), loop over these GSIs and add their provisioned
