Subject [jira] [Updated] (SOLR-9337) Add fetch() Streaming Expression
Date Mon, 25 Jul 2016 23:50:20 GMT

     [ https://issues.apache.org/jira/browse/SOLR-9337?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Joel Bernstein updated SOLR-9337:
---------------------------------
    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:

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