Joel Bernstein created SOLR-8962:
------------------------------------
Summary: Add sort Streaming Expression
Key: SOLR-8962
URL: https://issues.apache.org/jira/browse/SOLR-8962
Project: Solr
Issue Type: New Feature
Reporter: Joel Bernstein
Priority: Critical
The sort Streaming Expression does an in memory sort of the Tuples returned by
it's underlying stream. This is intended to be used for sorting sets gathered
during local graph traversals. This will make it easy to gather sets during a
traversal and use all of the sort based set operations (merge, innerJoin,
outerJoin, reduce, complement, intersect).
This will be particularly useful with the gatherNodes expression (SOLR-8925).
Sample syntax:
{code}
intersect(
sort(gatherNodes(), "fieldA asc"),
sort(gatherNodes(), "fieldA asc),
on)
{code}
