David Smiley commented on SOLR-11542:
-------------------------------------

I've started on some tests... which will also be useful to debug/understand the 
code path through DistributedURP.

What to do when a document's timestamp precedes the earliest collection?  
Probably fail -- but could be parameterized later to ignore/drop.

> Add feature to DistributedURP to route time partitioned collections

> 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 tentatively propose a helper class to DistributedURP to do 
> this.  Perhaps a separate URP is plausible, though it will take some 
> modifications to DistributedURP.
> 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.
