Metadata add vs set

[Americas]

When calling the Metadata.create() defined in this file the newly created Metadata object is populated by calling add, which first does a get to see if the property is set, and only then performs the set.

For an empty Metadata object, this is useless, why not use the set method, and skip the get call?

Thank you for the issue and question. Since keys in the metadata parameter is unique, there's no need to check for existing keys. You're right. 🎉

I believe this will improve the performance of creating metadatas. Can you create a pull request for this?

Yes, I can do the change 😄
