<div class="block">Information about a region. A region is a range of keys in the whole keyspace
of a table, an identifier (a timestamp) for differentiating between subset
ranges (after region split) and a replicaId for differentiating the instance
for the same range and some status information about the region.
The region has a unique name which consists of the following fields:
<ul>
<li> tableName : The name of the table </li>
<li> startKey : The startKey for the region. </li>
<li> regionId : A timestamp when the region is created. </li>
<li> replicaId : An id starting from 0 to differentiate replicas of the
same region range but hosted in separated servers. The same region range can
be hosted in multiple locations.</li>
<li> encodedName : An MD5 encoded string for the region name.</li>
</ul>
<br> Other than the fields in the region name, region info contains:
<ul>
<li> endKey : the endKey for the region (exclusive) </li>
<li> split : Whether the region is split </li>
<li> offline : Whether the region is offline </li>
