Przeglad formatu
ORC (.orc) files store optimized columnar datasets for analytics and warehouse workloads. Use sample ORC files to test reader compatibility, predicate pushdown behavior, and columnar migration workflows.
Glowne workflow dla ORC
- Columnar warehouse reader validation.
- Predicate pushdown and metadata inspection checks.
- Cross-format migration between ORC, Parquet, and Arrow.
Typowe bledy
- Only validating one columnar format and missing reader differences across ORC and Parquet.
- Ignoring metadata and predicate-path behavior when testing ORC inputs.
- Treating ORC fixtures as generic binaries without warehouse-reader validation.

Validation Methodology
- Validate extension and MIME detection before processing.
- Benchmark performance with small and larger files.
