- op00to 3y agoYes, but those mechanisms take time to determine this.
- bombcar 3y agoYou'd like to think so, but surprisingly large number of "large scale" things operate on the "everything is fine" until too many people complain about the fire.
- pixl97 3y agoCaches make problems fun too. Quite often you see automated tests that check how well your cache/in memory data are working. But when some other customer that isn't in the hot path tries to access their request times out. I've seen a lot of people making automated checking systems fail at things like this.
