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_s* field in the Tuples. The ExecutorStream will have an internal thread pool so expressions can be executed in parallel on 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} daemon(executor(threads=10, topic(storedExpressions, fl="expr", ...))) {code} In the example above a *daemon* wraps an *executor* which wraps a *topic* that is reading stored Streaming Expressions. The daemon will call the executor at intervals which will execute all the expressions retrieved by the topic. was: The *ExecutorStream* will wrap a stream which contains Tuples with Streaming Expressions to execute.
