distributed_cache_reader failed about yadcc HOT 3 CLOSED

I failed to see how is this possible.

Either the two timestamps are updated to the same value, or, in case an incremental update happens, the incremental timestamp is updated.

Given that the timestamp increments monotonically, the one updated more often (i.e., the incremental one) can only possibly be greater, not less.

Did you make some changes to the cache reader?

I'm just add a function, but this dose't affect their value.

bool DistributedCacheReader::CheckLucky(const std::string& key) {
  std::scoped_lock _(bf_lock_);
  if (last_bf_update_ + 10min >
          flare::ReadCoarseSteadyClock() /* It's still fresh (kind of). */
      && !cache_bf_.PossiblyContains(key)) {
    return false;
  }
  return true;
}

Simply adding a function shouldn’t make a difference, but if it’s called at inconvenient places things may change.

Try reverting local changes and see if code in master works.
