key bytes is bigger than redis memory used about redis-rdb-tools HOT 4 OPEN

Can you please share some details about your key?
what type is it?, what encoding (OBJECT ENCODING key)?, number of fields or elements in the key, and if you know their sizes.
what redis version are you using? version and architecture (32bit or 64bit)?

can you try modifying redis_memory_for_key.py and pass your correct redis version to the redis_version argument of MemoryCallback?

Thanks for replying.

it is a sorted set with 3801696 members. My redis version is 3.2.4.

I can't find where is the redis_memory_for_key.py. Can you tell me where to find it?

looks like you're already using the right version (by default it calculates memory usage of redis 3.2), so there's no need to edit that script.
anyway, it looks like the memory estimations for sorted sets are inaccurate.
they need to be improved, but i don't currently have time to handle that, so it may take time..

Got it.

Thanks for replying, wait for your good news : ).
