Feature request: save Export to io.Writer and Import from io.Reader

[erikdubbelboer]

Currently Export and Import use files. It would be nicer if we have versions with io.Writer and io.Reader so we can use other data sources such as S3 or HTTP requests.

Yup, makes sense!

Do you have in mind more something like db.Export(myWriter) where the user can / has to add compression and encryption by himself, or more db.Export(myWriter, true, "mySecret") which would add gzip compression and AES encryption like the current export/import do?

[erikdubbelboer]

Since the code is already there I think the second option would be nicer. If users want to do their own compression and encryption they still can be using db.Export(myWriter, false, "").

Sounds good 👍

I started already, but might only finish it over the weekend.

Hi @erikdubbelboer , I've implemented it. Would you mind reviewing:

• The export/write part: Export to io.Writer #71
• The import/read part: Import from io.Reader #72
• The example code that uses both: Add example code for S3 export/import #73 (still draft)

Looks good 👍

Thanks!
