I am trying to persist a given stream of data to an S3 compatible storage. The size is not known before the stream ends and can vary from 5MB to ~500GB.
I tried different possibilities but did not find a better solution than to implement sharding myself. My best guess is to make a buffer of a fixed size fill it with my stream and write it to the S3. Is there a better solution? Maybe a way where this is transparent to me, without writing the whole stream to memory?
The aws-sdk-go readme has an example programm that takes data from stdin and writes it to S3: https://github.com/aws/aws-sdk-go#using-the-go-sdk
When I try to pipe data in with a pipe
| I get the following error:
failed to upload object, SerializationError: failed to compute request body size
caused by: seek /dev/stdin: illegal seek
Am I doing something wrong or is the example not working as I expect it to?
I although tried minio-go, with PutObject() or client.PutObjectStreaming(). This is functional but consumes as much memory as the data to store.
- Is there a better solution?
- Is there a small example program that can pipe arbitrary data into S3?
