Feature/keep tgz download #7886
At the moment it is not possible. Partly, because this is a bit more than a feature, but it is also fixing some bugs. Read the rationale in the blog post: https://blog.conan.io/2020/11/05/New-conan-release-1-31.html.
Could you please give an order of magnitude of your developer caches sizes? Trying to understand a bit the pain and size of the issue.
In any case, the solution is likely to be based more on the ongoing work with the "LRU", and new features in order to keep the cache size limited. Have a look at: #7980
Our main product has a pkg size of ~ 2 GB (worst case) the SDK pkg ~ 300 MB. Also we have a other pkgs (e.g. Qt) with ~ 300MB if you store multiple versions of the pkgs, cache size of 20-30 GB are not unusual (Without tar.gz pkgs).
