| # This workflow is designed to keep specific caches on the main | |
| # branch from getting evicted according to the Github Actions policy | |
| # (currently in 2023: 7 days) in cases where the cost to construct | |
| # the cache is high, especially in cases where there is flakiness | |
| # (ex: network loss / throttling when downloading artifacts) involved in | |
| # constructing the cache. | |
| # | |
| # Preventing a cache from eviction using this workflow requires that: | |
| # - the cache is not too big that it starves other caches | |
| # from using the shared cache quota for the repository | |
| # - the cache key is specific enough to avoid cache collisions, according | |
| # to good cache key design | |
| # - the cache key is not overly specific to cause unnecessary cache misses | |
| # (resulting in duplicate caches values, thereby wasting space), according | |
| # to good cache key design | |
| # - For more details, see: https://docs.github.com/en/actions/using-workflows/caching-dependencies-to-speed-up-workflows | |
