Currently I have the following config re S3:
` aws {
s3 {
# default, used for any bucket not specified below
key: ""
secret: ""
region: ""

        credentials: [
            {
                # This will apply to all buckets in this host (unless key/value is specifically provided for a given bucket)
                host: "mydomain.com:9000"
                key: "minio"
                secret: "secret data"
                multipart: false
                secure: true
            }
        ]
    }
    boto3 {
        pool_connections: 512
        max_multipart_concurrency: 16
    }
} `
