s3bolt

Golang's bolt db wrapper that automatically loads and backup to s3

Purpose

s3bolt allows you to operate with bolt db with completelly transparent backup and restore to s3. It is intended for non-critical systems, due that:

• S3 is eventually-consistent. This means that after restoring from s3 you might not be loading last version.
• Every write operation triggers a push against s3, which clearly have an strong impact on performance.

Usage

Use s3bolt is pretty simple. Here you have a simplified example:

import "github.com/alanbover/s3bolt"

s3client, _ := s3bolt.NewS3Client(&s3bolt.SessionParameters{
    Region: "eu-west-1",
})
s3bolt := s3bolt.New(s3client, &s3bolt.Config{
    S3bucket: "someS3Bucket",
    S3prefix: "someS3Prefix",
})
db, _ := s3bolt.Open("/tmp/mydb", 0600, nil)
db.Update(func(tx *bolt.Tx) error {
    bucket, _ := tx.CreateBucketIfNotExists([]byte("someBucket"))
    bucket.Put([]byte("key"), []byte("value"))
    return nil
})
