> After HBASE-21657, Most subclass of Cell has a cached serialized size (Except
> those cells with tags), so I think most of the KeyValueUtil#length can be
> replaced by cell#getSerializedSize. Such as:
> - KeyValueUtil.length in StoreFlusher#performFlush;
> - KeyValueUtil.length in Compactor#performCompaction ;
> and so on..
> Will prepare a patch for this.
