<p>Version is an immutable snapshot of region’s metadata.</p>
|
||
<p>To read latest data from <code>VersionControl</code>, we should</p>
|
||
<ol>
|
||
<li>Acquire <code>Version</code> from <code>VersionControl</code>.</li>
|
||
<li>Then acquire last sequence.</li>
|
||
</ol>
|
||
<p>Reason: data may be flushed/compacted and some data with old sequence may be removed
|
||
and became invisible between step 1 and 2, so need to acquire version at first.</p>
