> Current segment auto merging logic will try to merge all segments, including all the recent segments. In some scenarios user don't want recent segments being merged because they may still undergo data updates. A "volatile time range" may be introduced to ease such cases. A "volatile time range" specify a recent time range, segments in this range will be immune from being auto merged.
