<div class="block">Compare two HBase cells. Do not use this method comparing <code>-ROOT-</code> or
<code>hbase:meta</code> cells. Cells from these tables need a specialized comparator, one that
takes account of the special formatting of the row where we have commas to delimit table from
regionname, from row. See KeyValue for how it has a special comparator to do hbase:meta cells and
yet another for -ROOT-.
<p>
While using this comparator for {<a href="#compareRows(org.apache.hadoop.hbase.Cell,org.apache.hadoop.hbase.Cell)"><code>compareRows(Cell, Cell)</code></a> et al, the hbase:meta cells
format should be taken into consideration, for which the instance of this comparator should be
used. In all other cases the static APIs in this comparator would be enough
<p>
HOT methods. We spend a good portion of CPU comparing. Anything that makes the compare faster
will likely manifest at the macro level.
