### Describe the problem you faced
Hi，
I have a simple MOR table, defined as follows:
```
create table test_hudi_table_mor (
a int,
b int,
c int
) using hudi
partitioned by (c)
options (
primaryKey = 'a',
preCombineField = 'b',
type = 'mor'
);
```
Then, I do insert for twice,
```
insert into test_hudi_table_mor values(1,1,1);
insert into test_hudi_table_mor values(2,2,2);
```
When I looked at the files created, I find two parquet files, no log files
Then, I do one update
```
update test_hudi_table_mor set b = 11 where a =1;
```
Then, I find a log file, so I would ask, why the two insert operations
doesn't generate log files and only update generate, thanks.
