[jira] [Updated] (SOLR-7525) Add ComplementStream
[ https://issues.apache.org/jira/browse/SOLR-7525?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Joel Bernstein updated SOLR-7525:
---------------------------------
Description:
This ticket adds a ComplementStream to the Streaming API and Streaming Expression language.
The ComplementStream will wrap two TupleStreams (StreamA, StreamB) and emit Tuples from StreamA that are not in StreamB.
Streaming API Syntax:
{code}
ComplementStream cstream = new ComplementStream(streamA, streamB, comp);
{code}
Streaming Expression syntax:
{code}
complement(search(...), search(...), on(...))
{code}
Internal implementation will rely on the ReducerStream.
