[Background]
Now update feature insert the updated rows into the old segments where the
data are updated.
In the end, it needs to reload the indexes of related segments.

[Movitation]
If there are many updated segments, it will take a long time to reload the
indexes again.
So I suggest writing the updated rows into a new segment.
It will not impact the indexes of old segments and doesn't need to reload
indexes.
