    Description

      Now that we have the UpdateStream it would be nice to support the use case of sending rolled up aggregates for storage in another SolrCloud collection. To support this we'll need to create id's for the aggregate records.

      The ConcatOperation would allows us to concatenate the bucket values into a unique id. For example:

      update(
                  select( 
                               rollup(search(q="*:*, fl="a,b,c", ...)), 
                               concat(fields="a,b,c", delim="_",  as="id")))
