I’m trying to run a pants job in a

matrix

on GitHub Actions. However, the keys for the lmdb store are based on the git sha which means they conflict and my caches aren’t merged properly. Is there any way to merge these appropriately or do I just need to convince my company to buy a remote caching service? 😄

Remote caching will solve it for sure. If the jobs are relatively independent, using a different cache key for each one might work well enough, too, at the cost of no sharing at all
