Feature request

Which Delta project/connector is this regarding?

  • Spark
  • Standalone
  • Flink
  • Kernel
  • Other (fill in here)

Overview

Motivation

The kernel benchmarking framework currently hard codes benchmark parameters. There are multiple ways users may want to augment a benchmark run including:

  • Filtering benchmark specs by name
  • Configure the number of warmup iterations
  • Configure the number of measurement iterations
  • Configure the warmup time.

Further details

Create a command line argument parser that accepts the above options as configurable parameters. Use the current parameters as the defaults for the benchmark.

For filtering benchmark specs, perform a substring match over each variant's full name. --include-test read_metadata For all other paramaeters, simply take an integer --warum-iterations 10

You can find the relevant file in kernel/kernel-defaults/src/test/java/io/delta/kernel/defaults/benchmarks/WorkloadBenchmark.java`

研究方向
Start by examining the file `kernel/kernel defaults/src/test/java/io/delta/kernel/defaults/benchmarks/WorkloadBenchmark.java` to understand the current hardcoded benchmark parameters. The task is to add a command line argument parser (e.g., using picocli or Apache Commons CLI) that accepts ` include test`, ` warmup iterations`, ` measurement iterations`, and ` warmup time` as options, while keeping the existing values as defaults. Look at how the benchmark is currently invoked and ensure the new CLI supports substring matching for test names and integer values for other parameters. Consider any existing test infrastructure or build configuration that might need updates.
