hubgeter opened a new pull request, #38245:
URL: https://github.com/apache/doris/pull/38245
## Proposed changes
fix a bug in DataTypeNullableSerDe.deserialize_column_from_fixed_json.
The expected behavior of the `deserialize_column_from_fixed_json` function
is to `insert` n values into the column.
However, when the `DataTypeNullableSerDe` class implements this function,
the null_map column is `resize` to n, which does not insert n values into it.
Since this function is only used by the `_fill_partition_columns` of the
`parquet/orc reader` and is not called repeatedly for a `get_next_block`, this
bug is covered up.
