Real key size

[Noam Sagi]

How can I tell the size of a key?

I'm using 'debug object' and looking at 'serializedlength' but it seems that this info is wrong.

How can I know the real size of a key?

MEMORY command in Redis >= 4.0 (currently in the "unstable" branch.
RC1 out as soon as I fix an Heisenbug with PSYNC2).

Thanks.

It works well for standard type, but crashes on my custom type. 

Should I check in my own code, or is it a current limitation?

Hi,

I think it doesn't work for lists as well. It shows a number ~1000x times higher than the real size...

Thanks,

Noam

If it crashes it's a bug, thanks. Please could you open an issue in
the Redis repo about that crash and the List issue you reported?
Thanks.
