per_file_caching = <bool>
default: False

Rather than formatting all files in a single batch, format each file as a separate process.

Why do this? You'll get many more cache hits. Why not do this? Formatters both have substantial startup overhead and are cheap to add one additional file to the run. On a cold cache, it is much faster to use --no-per-file-caching.

We only recommend using --per-file-caching if you are using a remote cache or if you have benchmarked that this option will be faster than --no-per-file-caching for your use case.
