    Description

      The fetch() Streaming Expression wraps another expression and fetches additional fields for documents in batches. The fetch() expression will stream out the Tuples after the data has been fetched. Fields can be fetched from any SolrCloud collection.

      Sample syntax:

      daemon(
             update(collectionC, batchSize="100"
                    fetch(collectionB, 
                          topic(checkpoints, collectionA, q="*:*", fl="a,b,c", rows="50"),
                          fl="j,m,z",
                          on="a=j")))
