s3_file_stream_in streams in AWS S3 file as a raw vector

s3_file_stream_out streams raw vector out to AWS S3 file

s3_file_stream_in(path, ...)

s3_file_stream_out(
  obj,
  path,
  max_batch = fs_bytes("100MB"),
  overwrite = FALSE,
  ...
)

Arguments

path

(character): A character vector of paths or s3 uri

...

parameters to be passed to s3_get_object and s3_put_object

obj

(raw|character): A raw vector, rawConnection, url to be streamed up to AWS S3.

max_batch

(fs_bytes): Maximum batch size being uploaded with each multipart.

overwrite

(logical): Overwrite files if the exist. If this is FALSE and the file exists an error will be thrown.

Examples

if (FALSE) {
# Require AWS S3 credentials

obj = list(charToRaw("contents1"), charToRaw("contents2"))

dir = s3_file_temp(tmp_dir = "MyBucket")
path = s3_path(dir, letters[1:2], ext = "txt")

s3_file_stream_out(obj, path)
s3_file_stream_in(path)
