S3

Deletes a file in a single request.

Reads a file in a single request. Suitable for small files.

For big files, consider using readFileMultipart instead.

Reads a file in multiple parts of the specified @partSize per request. Suitable for big files.

It does so in constant memory. So at a given time, only the number of bytes indicated by @partSize will be loaded in memory.

For small files, consider using readFile instead.

Uploads a file in a single request. Suitable for small files.

For big files, consider using uploadFileMultipart instead.

Uploads a file in multiple parts of the specified @partSize per request. Suitable for big files.

It does so in constant memory. So at a given time, only the number of bytes indicated by @partSize will be loaded in memory.

Note: AWS S3 API does not support uploading empty files via multipart upload. It does not gracefully respond on attempting to do this and returns a 400 response with a generic error message. This function accepts a boolean uploadEmptyFile (set to false by default) to determine how to handle this scenario. If set to false (default) and no data has passed through the stream, it will gracefully abort the multi-part upload request. If set to true, and no data has passed through the stream, an empty file will be uploaded on completion. An Option[ETag] of None will be emitted on the stream if no file was uploaded, else a Some(ETag) will be emitted. Alternatively, If you need to create empty files, consider using consider using uploadFile instead.

For small files, consider using uploadFile instead.
