Cache warming
Why do large services pre-warm caches before a big traffic event or after a cold start?
Options
- 1To reduce the cache's memory usage by loading only the entries that are requested first after start
- 2To increase the TTLs of the cached entries so that they stay valid for the whole traffic event
- 3To disable eviction entirely so that no cached entry is ever removed while the event is running
- 4So the hot working set is already resident, avoiding a cold-cache miss storm that could overwhelm the DB
