Reviewers are 4.5x more likely to request changes on larger PRs vs. smaller ones

TL;DR

  • Reviewers request changes for 2% of PRs under 50 lines modified , but that number jumps up to 9.4% when we look at PRs with 1001-2000 lines modified. We see a dip when PRs exceed 5,000 lines modified, but that may be driven by migrations.
    • 50% of reviewed PRs are under 50 lines, while 6% of reviewed PRs are over 1000 lines.

% of reviewed PRs with changes requested during review

  • We also see that reviewers of larger PRs are 3x more likely to either request changes or just leave a comment without approving.

% of reviewed PRs with changes requested or commented outcomes during review

  • Interestingly, we see that smaller PRs are most likely to receive multiple reviews, while larger PRs overwhelming receive 1 review.

% of reviewed PRs that received more than 1 review

Methodology:

  • We limited PRs to those by active committers from 1/2023 to now.
  • We limited to PRs that were merged after at least one review
