>
> Currently, the KinesisReceiver can loose some data in the case of certain
> failures (receiver and driver failures). Using the write ahead logs can
> mitigate some of the problem, but it is not ideal because WALs dont work with
> S3 (eventually consistency, etc.) which is the most likely file system to be
> used in the EC2 environment. Hence, we have to take a different approach to
> improving reliability for Kinesis.
