What's New?

Amazon SimpleDB BatchDeleteAttributes The new BatchDeleteAttributes operation in Amazon SimpleDB allows you to perform multiple DeleteAttributes operations in a single call, which reduces round trips and latencies. This enables applications to send more optimized delete requests, which yields better throughput.

Using BatchDeleteAttributes is easy:

AmazonSimpleDBClient sdb = new AmazonSimpleDBClient(myCredentials);

sdb.batchDeleteAttributes(new BatchDeleteAttributesRequest(myDomainName, myListOfItemsToDelete));
Amazon EMR StepFactory Support for Hive Versions The Amazon Elastic Map Reduce StepFactory utility now allows you to specify specific versions of Hive to install as part of your Job flows.
Bug Fixes and Enhancements Lots of important bug fixes and enhancements, particularly for the Amazon S3 client:
  • Fixed a data corruption issue with TransferManager for files over 2GB.
  • Improved thread synchronization in TransferManager.
  • Fixed a bug causing a NullPointerException when requesting object metadata.
  • New shutdownNow() method (similar to ExecutorService#shutdownNow()) to shutdown TransferManager's resources.
