/**
* Container for the parameters to the {@link com.amazonaws.services.dynamodbv2.AmazonDynamoDB#batchWriteItem(BatchWriteItemRequest) BatchWriteItem operation}.
*
* 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.
*
*
* NOTE: BatchWriteItem cannot update items. To update items, use
* the UpdateItem API.
*
*
* 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 .
*
*
* IMPORTANT: 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, go to 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, such as
* Java, 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, such as PHP, you must update or delete
* the specified items one at a time. In both situations,
* BatchWriteItem provides an alternative where the API 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.
*
*
* -
* You try to perform multiple operations on the same item in the same
* BatchWriteItem request. For example, you cannot put and delete
* the same item in the same BatchWriteItem request.
*
*
* -
* There are more than 25 requests in the batch.
*
*
* -
* Any individual item in a batch exceeds 400 KB.
*
*
* -
* The total request size exceeds 16 MB.
