Presently task workers can only run a single request at a time. This is useful when code needs to be run in an isolation environment for security. In cases when isolated environment is not necessary, task workers can be allowed to run requests in parallel. This will increase the number of design time operations that can be handled with the same number of task workers.
Release Notes
Task workers can run requests concurrently if isolation is not required during user code execution. This behaviour is controlled using cdap-site properties `task.worker.request.userCodeIsolation.enabled` and `task.worker.request.limit`
