On s3 limit the max object size to 1GiB when the size is not provided (-1) or the minio client will calculate a big part size since it tries to use the maximum object size (5TiB) and will allocate a very big buffer in ram. Also leave as commented out the previous hack that was firstly creating the file locally to calculate the size and then put it (for future reference).
