Integrate with go-storage to allow using various storage service as storing location

[Xuanwo]

Background

go-storage is an application-oriented unified storage layer for Golang which allows the user to connect various storage services with the same interface. For now, go-storage supports s3, gcs, azblob, oss, cos, and more supports are on the way: beyondstorage/go-storage#536.

Proposal

I propose to integrate lotus with go-storage to allow using various storage service as storing location.

After this proposal implemented, we can add s3 service (gcs, azblob, minio and any other object storage services):

lotus-miner storage attach --init --store s3://bucket_name/path

Implementations

Need Support

Future

go-storage intends to build a unified storage layer, so we are not limited to object storage services, dropbox, ipfs is also on our roadmap.

After these services implemented, we can:

lotus-miner storage attach --init --store ipfs://node_id/path

Looks interesting?
