gphotos-uploader-cli | Command Line Google Photos Uploader | REST library

I'm developing this CLI to upload images to Google Photos. The CLI creates several go routines to upload files in parallel 1. Once it's uploaded, the same routine adds it to an Album. These albums are created if they didn't exist before 2.

Due to the concurrency and the fact that Google Photos API allows the creation of two Albums with the same name, I'm having duplicated album names that I'd like to avoid.

The GetOrCreateAlbumByName() 3 doesn't ensure that the Album is unique. It basically ask if an album exists with the same name and if not, it will create a new one. But this function could be called in parallel so two Album with the same name could be created. Besides it's implementing a mutex, I'm observing duplicates.

How would yo recommend to deal with that?

1. Create a Worker (like a microservice) that deal with album creation. Each go routine will be blocked until the album is created. It will remove concurrency on the Album creation part.
2. Maintain an album cache and use it to check if the album has been already created. In that case, race condition could happen too, but with less probability.
3. Using 1 and 2 together.
4. Other, please specify.

I have concerns about 1, 2 and 3... that's why I would like to know how you would deal with that.

Thanks in advance
