Dennis Gove commented on SOLR-8556:
-----------------------------------
{code}
buf.append(field);
{code}
This concatenates the fields together instead of the values of the fields
together.
> Add ConcatOperation to be used with the SelectStream

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