Create new Control Records that will serve as the header and footer for a Metadata Snapshot File. These records will be contained at the beginning and end of each Snapshot File, and can be checked to verify completeness of a snapshot file.
The following fields are added to the Header:
- Version : Schema version for the snapshot header
- Last Contained Log Time : The append time of the highest record contained in this snapshot
- Version : Schema version of the snapshot footer (same as header)**
