> Currently, each key corresponds to one single SCM block, and putKey/getKey
> writes/reads to this single SCM block. This works fine for keys with
> reasonably small data size. However if the data is too huge, (e.g. not even
> fits into a single container), then we need to be able to partition the key
> data into multiple blocks, each in one container. This JIRA changes the
> key-related classes to support this.
