# 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 | |
