Thundering herd on cache key deletion
A deploy flushes the entire cache at once. What is the immediate risk?
Options
- 1Cache hits increase because the cache refills very quickly from the database after the flush
- 2The TTLs all become infinite, so cached entries never expire and stay resident in memory
- 3A thundering herd: all requests miss and hit the backend simultaneously, potentially overloading the DB
- 4The DB connection pool shrinks because idle connections are reclaimed during the flush event
