master-slave situation,the same key has different LFU via OBJECT FREQ command.

This can be created easily by following steps:

1. 'config set lfu-decay-time 0' in master and slave.(we can check LFU all the time)
2. 'set str lfutest' and 'redis-benchmark -n 10000 get str' in master.
3. str's LFU is 56 via 'object freq str' in master.
4. str's LFU is 5 via 'object freq str' in slave.

i know the reason is that only write commands in master-slave replication !
but i think if failover happend, the hot keys may be evicted in new master !

By the way,Can I dynamically modify the key's LFU ?
