Does shorter key names has any effect on the size of metadata

I’m realizing that metadata does affect the storage capacity of the pod.

That is 100% true for the values. But what about the keys?
Would it make a difference if I name the key ‘a’ instead of ‘page_uuid’, for example?

Thanks

Hello and welcome to the community forums @marouen!

To answer your question, yes, the key’s length contributes to the metadata’s overall size.

Regarding your example, renaming your metadata key from page_uuid to a saves you 8 bytes. For a million entries, that’s less than 8 MB. So at the current $0.33/GB/mo price, you’ll save less than $0,002 per million vectors per month. Not sure if that’s worth the obfuscation :wink:

One use case where that may make sense is when your current metadata per vector is slightly over the 40KB limit. In such a case, reducing the keys’ lengths may be a way to fit within the limit (especially if you have many long keys).
