<div class="block">Stores minimum and maximum timestamp values, it is [minimumTimestamp, maximumTimestamp] in

Use <a href="../../../../../org/apache/hadoop/hbase/io/TimeRange.html" title="class in org.apache.hadoop.hbase.io"><code>TimeRange</code></a> at read time instead of this. See toTimeRange() to make TimeRange to use.
MemStores use this class to track minimum and maximum timestamps. The TimeRangeTracker made by
the MemStore is passed to the StoreFile for it to write out as part a flush in the the file
metadata. If no memstore involved -- i.e. a compaction -- then the StoreFile will calculate its
own TimeRangeTracker as it appends. The StoreFile serialized TimeRangeTracker is used
at read time via an instance of <a href="../../../../../org/apache/hadoop/hbase/io/TimeRange.html" title="class in org.apache.hadoop.hbase.io"><code>TimeRange</code></a> to test if Cells fit the StoreFile TimeRange.</div>

<div class="block">This method used to serialize TimeRangeTracker (TRT) by protobuf while this breaks the
forward compatibility on HFile.(See HBASE-21008) In previous hbase version ( < 2.0.0 ) we use
DataOutput to serialize TRT, these old versions don't have capability to deserialize TRT
which is serialized by protobuf. So we need to revert the change of serializing
TimeRangeTracker back to DataOutput. For more information, please check HBASE-21012.</div>
