             Summary: UDF evaluation should be able to use compiler parallelism 
setting
                 Key: ASTERIXDB-2152
                 URL: https://issues.apache.org/jira/browse/ASTERIXDB-2152
             Project: Apache AsterixDB
          Issue Type: Bug
            Reporter: Xikui Wang


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.
