issue: https://github.com/milvus-io/milvus/issues/45006 ref: https://github.com/milvus-io/milvus/issues/42148 Previsouly, the parquet import is implemented based on that the STRUCT in the parquet files is hanlded in the way that each field in struct is stored in a single column. However, in the user's perspective, the array of STRUCT contains data is something like STRUCT_A: for one row, [struct{field1_1, field2_1, field3_1}, struct{field1_2, field2_2, field3_2}, ...], rather than {[field1_1, field1_2, ...], [field2_1, field2_2, ...], [field3_1, field3_2, field3_3, ...]}. This PR fixes this. --------- Signed-off-by: SpadeA <tangchenjie1210@gmail.com>
