Apache Parquet, a columnar storage format for big-data analytics.
| 0x00000000 | 50415231 | PAR1 | 'PAR1' header |
| -0x00000004 | 50415231 | PAR1 | 'PAR1' footer (last 4 bytes) |
Parquet stores data column-by-column with rich compression and metadata, making analytical queries over huge datasets fast. Uniquely it is marked at both ends: the four bytes 'PAR1' appear at the start and again at the very end of the file.
