<div class="block">Performs compaction on a column family with the mob flag enabled. This works only when MOB
compaction is explicitly requested (by User), or by Master There are two modes of a MOB
compaction:<br>
<p>
<ul>
<li>1. Full mode - when all MOB data for a region is compacted into a single MOB file.
<li>2. I/O optimized mode - for use cases with no or infrequent updates/deletes of a <br>
MOB data. The main idea behind i/o optimized compaction is to limit maximum size of a MOB file
produced during compaction and to limit I/O write/read amplification.
</ul>
The basic algorithm of compaction is the following: <br>
1. If the Put cell has a mob reference tag, the cell's value is the path of the mob file.
<ol>
<li>If the value size of a cell is larger than the threshold, this cell is regarded as a mob,
directly copy the (with mob tag) cell into the new store file.</li>
<li>Otherwise, retrieve the mob cell from the mob file, and writes a copy of the cell into the
new store file.</li>
</ol>
2. If the Put cell doesn't have a reference tag.
<ol>
<li>If the value size of a cell is larger than the threshold, this cell is regarded as a mob,
write this cell to a mob file, and write the path of this mob file to the store file.</li>
<li>Otherwise, directly write this cell into the store file.</li>
