Я пытаюсь загрузить большой файл (на данный момент 90 МБ) на S3, используя Akka HTTP с коннектором Alpakka S3. Он отлично работает для небольших файлов (25 МБ), но когда я пытаюсь загрузить большой файл (90 МБ), я получаю следующую ошибку:

Хотя в конце я получаю сообщение об успехе, но файл загружен не полностью. Он загружается только 45-50 МБ.
Я использую следующий код: S3Utility. scala
class S3Utility(implicit as: ActorSystem, m: Materializer) {
private val bucketName = "test"
def sink(fileInfo: FileInfo): Sink[ByteString, Future[MultipartUploadResult]] = {
val fileName = fileInfo.fileName
S3.multipartUpload(bucketName, fileName)
}
}
Маршруты:
def uploadLargeFile: Route =
post {
path("import" / "file") {
extractMaterializer { implicit materializer =>
withoutSizeLimit {
fileUpload("file") {
case (metadata, byteSource) =>
logger.info(s"Request received to import large file: ${metadata.fileName}")
val uploadFuture = byteSource.runWith(s3Utility.sink(metadata))
onComplete(uploadFuture) {
case Success(result) =>
logger.info(s"Successfully uploaded file")
complete(StatusCodes.OK)
case Failure(ex) =>
println(ex, "Error in uploading file")
complete(StatusCodes.FailedDependency, ex.getMessage)
}
}
}
}
}
}
Любая помощь будут оценены. Спасибо
