### Describe the problem you faced
I am using Hudi 0.15.0 and Spark SQL, and do the following operations,
I insert two records into the table hudi_cow_20251211 one by one, and when I
query the table, I find that these two records go to the same parquet file,
which looks incorrect to me, they should belong two parquet files.
```
set hoodie.datasource.write.operation=insert;
set hoodie.spark.sql.insert.into.operation=insert;
CREATE TABLE IF NOT EXISTS hudi_cow_20251211 (
a INT,
b INT,
c INT
)
USING hudi
tblproperties(
type='cow',
primaryKey='a',
preCombineField='c'
)
insert into hudi_cow_20251211 select 1,1,1;
insert into hudi_cow_20251211 select 1,11,111;
```
Then, I query the table `select * from hudi_cow_20251211;`, the result is
```
20251211201308842 20251211201308842_0_0 1
966b7c8e-66e6-40b7-badf-fe4234bb9f23-0_0-270-227_20251211201314945.parquet
1 1 1
20251211201314945 20251211201314945_0_1 1
966b7c8e-66e6-40b7-badf-fe4234bb9f23-0_0-270-227_20251211201314945.parquet
1 11 111
```
I wonder why the two records (two commits) go to the same parquet
file(966b7c8e-66e6-40b7-badf-fe4234bb9f23-0_0-270-227_20251211201314945.parquet
), i think they should be created in two different parquet files(each respect
one file slice), I want to ask whether I have missed something.
