Monitor big keys on Valkey

[prd-vuong-huynhphuc]

Currently, Valkey does not provide a straightforward way to monitor or alert when certain keys become very large (for example, a single string key or hash field reaching 500MB). In high-traffic environments, big keys can cause:

• Latency spikes when accessed (GET, HGETALL, etc.)

• Memory fragmentation or eviction pressure

• Blocking during RDB/AOF persistence

Why it is closed? I think this is a good topic

@hwware Thanks.
I found this command COMMANDLOG GET(https://valkey.io/commands/commandlog-get/)
and I think it could be useful for this case. However, do you think it might affect performance under high load, since its complexity is O(N)?
