A large pull request can be difficult to navigate: it degrades browser performance and can distract reviewers from the important details.
To improve your code review experience in Bitbucket Cloud, repository administrators now have the ability to exclude files from pull requests using pattern matching.
By excluding certain files from the pull request, repository administrators can make the review process cleaner and more efficient.
Excluded files only work with the new pull request experience. Make sure that feature is enabled in Bitbucket Labs for each reviewer who wants to review smaller pull requests.
Use excluded files to turn a long, unwieldy review process like this… 
into a more seamless, manageable experience
Large pull requests frequently contain noise in the form of package manager lock files, minified Javascript or CSS, or other computer-generated text files. While it’s important for developers to commit the files to the repository and to see when any changes are made, reviewers oftentimes don’t need to review all the specific details.
For example, the screens above show how a one-line change to package.json results in a diff of 1,690 lines in yarn.lock.
Excluded files gives administrators full control over which files appear in pull requests. The filenames for all the files still remain in the pull request, but the diff for each excluded file is replaced with an informational card including a link to the file’s diff.
To exclude files in pull requests for a repo, add patterns to the list at Settings > Excluded files in the Pull Requests section.
