Hello guys! Does gcs account need to have Delete permissions on buckets to be used in flyte files operations ? getting this error when using

FlyteDirectory(path='path/to/parent', remote_directory='<gs://datasets_bucket/path/to/parent>')

... and many more.

why delete when it is trying to upload? and if the directory path/to/parent does not exist or empty, does it delete contents of gcs corresponding path ?

this is because of how composition works. composition is used for uploading large files to GCS. basically the file is chunked, chunks are uploaded individually, and composed back into its original form in GCS. the last step is to delete the temporary chunked files.

Thanks! that explains alot. @Ariel Kaspit
