------------------------------------
Summary: Add fetch() Streaming Expression
Key: SOLR-9337
URL: https://issues.apache.org/jira/browse/SOLR-9337
Project: Solr
Issue Type: New Feature
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Joel Bernstein
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(
fetch(collectionB,
topic(checkpoints, collectionA, q="*:*", fl="a,b,c", rows="50"),
fl="j,m,z",
on="a=j"))
{code}
