```

 I think the point [@jiegzhan|https://github.com/jiegzhan] pointed out is 
reasonable, for insert operation, we should not update the existing records. 
Right now the behavior/result is different when setting different small file 
limit, when it is set to 0, the new inserts will not update the old records and 
write into a new file, but when it is set to other value such as 128M, the new 
inserts may update the old records lies in small file picked up the 
UpsertPartitioner.
