Joel Bernstein commented on SOLR-8213:
--------------------------------------
A little more information on how the parallelism is accomplished in the
SQLHandler.
If you look through the code in the SQLHandler you'll find a few places where
the ParallelStream is used. In these scenarios the ParallelStream wraps another
stream, for example the RollupStream, and sends it to worker nodes. It does
this by calling toExpression() on the underlying stream which creates a
Streaming Expression which is sent across the wire to the /stream handler on
the workers. The workers run the expression and stream tuples back to the /sql
handler for further processing. So it's the ParallelStream that would need to
be adjusted if AUTH is to be passed through to the workers.
