Redis [QUESTION] used_memory_peak_perc always reach 100%

Hello Redis folks!

I deployed Redis Cluster on 3 nodes, each node has 2 Redis instances. When I check the memory usage on each node, used_memory_peak_perc always reach 100%.

$ info memory
# Memory
used_memory:538476920
used_memory_human:513.53M
used_memory_rss:3608576
used_memory_rss_human:3.44M
used_memory_peak:538517872
used_memory_peak_human:513.57M
used_memory_peak_perc:99.99%
used_memory_overhead:538401824
used_memory_startup:1464296
used_memory_dataset:75096
used_memory_dataset_perc:0.01%

I also update maxmemory to higher value, but nothing changes. I wander check this value used_memory_peak_perc is affected to our system or not and how can I fix this issue.

Thank for helps~

see https://redis.io/commands/info used_memory_peak_perc is relative to used_memory, not to the maxmemory
