Description

Add a set of benchmarks with varying stripe/rowgroup sizes to each affected component:

  • ORC reader
  • ORC writer
  • Parquet reader
  • Parquet writer

Use the new benchmarks to evaluate the effects of these options and potentially determine the optimal settings.

Contributor guide

Research direction
Examine the existing benchmark infrastructure in the cuDF repository, likely under `benchmarks/`. Review the current ORC and Parquet reader/writer benchmarks to understand the pattern. Look through the issue comments for suggestions on stripe/rowgroup sizes. Propose a set of sizes (e.g., 1MB, 10MB, 100MB) to test and determine optimal settings. Consider using existing benchmark utilities to minimize new code.
