1. Use Minimal Mode for Large Datasets (+3)

1. Use Minimal Mode for Large Datasets

# GOOD: Minimal mode for large data
profile = ProfileReport(large_df, minimal=True)

# AVOID: Full explorative on large data
# profile = ProfileReport(large_df, explorative=True)  # Slow!

2. Sample for Initial Exploration

# GOOD: Sample first, then full profile
sample = df.sample(n=10000, random_state=42)
profile = ProfileReport(sample, title="Sample Profile")

# If interesting, profile full data
# profile_full = ProfileReport(df, minimal=True)

3. Customize for Your Needs

# GOOD: Disable unnecessary computations
profile = ProfileReport(
    df,
    correlations={"pearson": {"calculate": True}},  # Only Pearson
    missing_diagrams={"bar": True, "matrix": False, "heatmap": False}
)

4. Use Lazy Evaluation

# GOOD: Lazy profile, compute when needed
profile = ProfileReport(df, lazy=True)
# ... do other work ...
profile.to_file("report.html")  # Computes here
