| The mixed_types_delta_length_byte_array.parquet file was generated with the | |
| parquet_files_generator.py script, which uses PyArrow (https://arrow.apache.org/docs/python). | |
| The file encodes BYTE_ARRAY columns (str_col, bin_col) using the | |
| DELTA_LENGTH_BYTE_ARRAY Parquet encoding (enum value 6). | |
| To regenerate the file, run from IMPALA_HOME: | |
| python3 testdata/parquet_delta_length_byte_array_encoding/parquet_files_generator.py |
