You will see something similar to this when running the plugin with spaceflight project:

Requirements

kedro>=0.18.5 # Minimal version for hook specifications
pandas>=1.0.0

Get Started

If you do not have kedro installed already, install kedro with: pip install kedro

Then create an example project with this command: kedro new --example=yes --tools=none --name kedro-profile-example

If you are cloning the repository, the project is already created here

This will create a new directorykedro-profile-example in your current directory.

Enable the Profiling Hook

You will find this line in settings.py, update it as follow:

from kedro_profile.hook import ProfileHook

HOOKS: tuple[ProfileHook] = (
    ProfileHook(
        save_file=True,  # Enable CSV file saving
        node_profile_path="data/08_reporting/profiling/node_profile.csv",
        dataset_profile_path="data/08_reporting/profiling/dataset_profile.csv",
    ),
)

Configuration Options

• save_file: Boolean to enable/disable CSV file saving (default: False)
• node_profile_path: Path for node performance CSV file (default: "node_profile.csv")
• dataset_profile_path: Path for dataset performance CSV file (default: "dataset_profile.csv")
• env: Environment filter (default: "local")

Example Configurations

Save to custom directory:

HOOKS: tuple[ProfileHook] = (
    ProfileHook(
        save_file=True,
        node_profile_path="reports/node_performance.csv",
        dataset_profile_path="reports/dataset_performance.csv",
    ),
)

Disable CSV saving (console output only):

HOOKS: tuple[ProfileHook] = (
    ProfileHook(save_file=False),
)

Output

The plugin generates two CSV files when save_file=True:

1. Node Profile: Contains node execution times and performance metrics
2. Dataset Profile: Contains dataset loading/saving times and access counts

Both files include:

• Load/Save counts
• Loading/Saving times
• Total time calculations
• Sorted by total time (descending)

Environment Variables

• KEDRO_PROFILE_DISABLE=1: Disable profiling
• KEDRO_PROFILE_RICH=0: Disable rich console output
