Joel Bernstein updated SOLR-9559:
---------------------------------
    Description: 
The ExecutorStream will wrap a stream which contains Tuples with Streaming 
Expressions to execute. By default the ExecutorStream will look for the 
expression in the *expr* field in the Tuples.

The ExecutorStream will have an internal thread pool so expressions can be 
executed in parallel in a single worker. The ExecutorStream can also be wrapped 
by the parallel function to partition the Streaming Expressions that need to be 
executed across a cluster of worker nodes.

Sample syntax:
{code}
executor(topic(storedExpressions, fl="expr", ...))
{code}
