Very slow when many files match filter

[jnicoulaud-ledger]

Description:
We use the action on a repository that contains 10K+ files, with filters:

assets:
  - changed-files:
      - any-glob-to-any-file: ['inputs/**', 'outputs/**']

When many files changes, the action runs very slow (up to 30 minutes for 10K+ files). It looks like the implementation goes over all files instead of stopping as soon as one is matched.

Action version:
v5.0.0

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Repro steps:

• Create a repo with 100K files
• Configure labeler with a glob pattern to match those files
• Create a commit that modifies all files

Expected behavior:
Action runs in a few seconds

Actual behavior:
Action runs very slow

Hi @jnicoulaud-ledger, thank you for bringing this up. The current behavior of actions/labeler is to scan all files across the PRs, which is expected. We will consider this as a feature request for future updates
