Hello, I have a question regarding Client-Side Caching Server Side Implementation, in https://github.com/redis/redis/blob/unstable/src/tracking.c#L360, trackingInvalidateKeysOnFlush function, we sent out tracking invalidation messages to all the clients which enabled tracking, no matter whether it is FLUSHDB or FLUSHALL case. however, Why we only clean up the tracking table for FLUSHALL case only? I think we can safely clean up the tracking table no matter whether it is FLUSHDB or FLUSHALL case, since the invalidation message for both cases are sending out, and this feature doesn't distinguish for DB. Or am I missing something? Thanks!
