Is it normal that

named_caches

gets very large over time? I use pex inside my devcontainer and mounted the

named_caches

directory so that it persists over rebuilds. But I a few weeks later I saw that this directory grew to 40GB in size. I don't want to delete the whole directory, because rebuilding takes much time. I use pants export to export the virtual env which is quite fast when having

named_caches

.

Yes, that seems normal. The

named_caches

cache all the parts of all your pexes/dists. There is structure sharing, so you don't have multiple copies of the same wheels, but it does all add up. There is no cache eviction logic.
