Is it normal to see lmdb_store occupying 200+ GB on a CI runner machine?

Unrelated to CI, but yeah, the caches are able to grow without bound. Take a read through these two pages for more info/suggestions https://www.pantsbuild.org/2.19/docs/using-pants/using-pants-in-ci#directories-to-cache https://github.com/pantsbuild/actions/tree/main/init-pants#input

Whats the impact of not using local cache?
