compressbench
Benchmark compression algorithms on Parquet datasets.
Why
Compression settings affect performance, storage cost, and latency — but most data engineers inherit defaults without testing.
compressbench lets you benchmark compression ratio, compression speed, and decompression speed across algorithms using your own Parquet files.
Features
- Accepts local Parquet files as input.
- Supports gzip and snappy.
- Outputs:
- Compression ratio.
- Compression time.
- Decompression time.
- CLI built with Typer.
- Unit tests with pytest.
Installation
pip install compressbench
Usage
compressbench input.parquet --algorithms gzip snappy If --algorithms is omitted, runs benchmarks for all available algorithms.
Example Output Algorithm: gzip Compression ratio: 2.91 Compression time: 0.43s Decompression time: 0.12s
Algorithm: snappy Compression ratio: 1.67 Compression time: 0.12s Decompression time: 0.05s
CLI Options
input.parquet Path to the Parquet file to benchmark. --algorithms List of algorithms to test (gzip, snappy). --level Not supported in v0.1.0. Reserved for future versions.
