Description

With the compiler parallelism setting, the user should be able to utilize multiple cores to evaluate the user-defined-function in feed pipeline.

Expected user experience:
SET `compiler.parallelism` "7";
start feed TweetFeed;

Note that the parallelism parameter needs to be set when we start the feed.
