The default behavior for stream processing in Lambda functions enables entire batches of messages to succeed or fail. You can also use batch bisecting functionality to retry batches iteratively if a single message fails. Now with custom checkpoints, you have more control over handling failed messages.

With tumbling windows, you can calculate aggregate values in near-real time for Kinesis data streams and DynamoDB streams. Unlike existing stream-based invocations, state can be passed forward by Lambda invocations. This makes it easier to calculate sums, averages, and counts on values across multiple batches of data.
