Please describe the end goal of this project

Proposing a path structure that tries to distribute all shards deterministically over multiple prefixes. The end goal of this initiative is to reduce the throttling or rate limiting done by cloud providers. The organic recommendation in such cases by the same cloud providers is to distribute the load to them over multiple prefixes. In this meta, we will breakdown the issue to smaller issues that we would be working on to complete this feature request.
