<div class="block">Manages the store files and basic metadata about that that determines the logical structure (e.g.
what files to return for scan, how to determine split point, and such). Does NOT affect the
physical structure of files in HDFS. Example alternative structures - the default list of files
by seqNum; levelDB one sorted by level and seqNum.
<p/>
Notice that, all the states are only in memory, we do not persist anything here. The only place
where we throw an <a href="https://docs.oracle.com/javase/8/docs/api/java/io/IOException.html?is-external=true" title="class or interface in java.io"><code>IOException</code></a> is the <a href="../../../../../org/apache/hadoop/hbase/regionserver/StoreFileManager.html#getSplitPoint--"><code>getSplitPoint()</code></a> method, where we need to
read startKey, endKey etc, which may lead to an <a href="https://docs.oracle.com/javase/8/docs/api/java/io/IOException.html?is-external=true" title="class or interface in java.io"><code>IOException</code></a>.
