Major Description
Assuming we have some time partitioning metadata on an alias (see SOLR-11487 for the metadata facility), we'll then need to route documents to the right collection. I propose a new URP. (edit: originally it was thought DistributedURP would be modified but thankfully we can avoid that).
The scope of this issue is:
- decide on some alias metadata names & semantics
- decide the collection suffix pattern. Read/write code (needed to route).
- the routing code
No new partition creation nor deletion happens is this issue.
