}
public func getStorageTier(for videoId: String, frameNumber: UInt64, accessPattern: AccessPattern = .hot) -> StorageTier {
switch accessPattern {
case .hot:

let url = URL(string: "\(endpoint)/\(bucket)/\(key)")!
var request = URLRequest(url: url)
request.httpMethod = "PUT"
request.httpBody = data
addAuthHeaders(request: &request, method: "PUT", path: "/\(bucket)/\(key)")
// URLSession upload operation...
}
