> 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*
