Rate limiting for Actions cache entries

GitHub Actions cache now has a rate limit of 200 uploads per minute per repository. This limit only impacts uploads of new cache entries—it does not affect cache entries that are downloaded during job runs.

We implemented this limit in response to repositories that upload a high volume of cache entries in very short periods, which can cause cache thrashing and impact system stability. We are working with the authors of some Marketplace actions to adopt behaviors that reduce these challenges.

Users impacted by the rate limits can expect some new cache entry uploads to be rejected until the rate limit resets.
