> 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.
