             Summary: Collection Alias metadata for time partitioned collections
                 Key: SOLR-11487
                 URL: https://issues.apache.org/jira/browse/SOLR-11487
             Project: Solr
          Issue Type: Sub-task
      Security Level: Public (Default Security Level. Issues are Public)
          Components: SolrCloud
            Reporter: David Smiley


SOLR-11299 outlines an approach to using a collection Alias to refer to a 
series of collections of a time series. We'll need to store some metadata about 
these time series collections, such as which field of the document contains the 
timestamp to route on.

The current {{/aliases.json}} is a Map with a key {{collection}} which is in 
turn a Map of alias name strings to a comma delimited list of the collections.
_If we change the comma delimited list to be another Map to hold the existing 
list and more stuff, older CloudSolrClient (configured to talk to ZooKeeper) 
will break_.  Although if it's configured with an HTTP Solr URL then it would 
not break.  There's also some read/write hassle to worry about -- we may need 
to continue to read an aliases.json in the older format.

Alternatively, we could add a new map entry to aliases.json, say, 
{{collection_metadata}} keyed by alias name?

Perhaps another very different approach is to attach metadata to the configset 
in use?
