Download an Object from MinIO to Disk — minio_download

Downloads an object stored in a MinIO bucket and saves it to a local file. Before downloading, the function checks whether the object exists using minio_object_exists. If the object does not exist, an error is raised.

Usage

minio_download_object(bucket, object, destfile, use_https = TRUE, region = "")

Arguments

bucket: Character. Name of the MinIO bucket.
object: Character. Object key (path) within the bucket.
destfile: Character. Local file path where the downloaded object will be saved.
use_https: Logical. Whether to use HTTPS when connecting to MinIO.
region: Character. Region string required by aws.s3.

Value

Invisibly returns destfile.

Details

The download is streamed directly to disk (i.e., the full object is not loaded into memory).

Examples

if (FALSE) { # \dontrun{
minio_download_object(
  bucket = "assets",
  object = "path/file.parquet",
  destfile = "path/file.parquet"
)
} # }
