Does Backblaze offer strong consistency for files?
The killer feature of Google Cloud Storage in my eyes is its ability to be strongly consistent, if you set the right HTTP headers. This is not possible for Amazon S3, which is always eventually consistent and makes it unusable for many use cases where you need to be able to guarantee that customers will always see the newest version of a file.
- kcolford 6y agoI know that the underlying backbaze b2 is strongly consistent because of how they shard it. You get a different download endpoint depending on your bucket corresponding to the data centre. Not sure how they implemented their S3 endpoint though so that will be interesting.
- nilayp 6y agoNilay from Backblaze here. Yes - B2 is strongly consistent. When you upload an object using either the B2 Native or S3 API - the object is persisted to the final resting place before the upload completes. Therefore, you can list/download the file immediately after your upload completes.
