Consider I have SCDF (Spring cloud dataflow 2.5.1) deployed at local and I have created 7 tasks named - composed-task-runner and task2, task3 etc.. I have created a composed task which call tasks one after another based on preferences set. I am getting logs from SCDF in temp directory and all other tasks logs in same temp directory but in different folders but

1. I would like to aggregate all the logs from each task along with SCDF logs in one folder/file. How can we do this? I tried setting LOG_FILE and LOG_LOCATION as args while starting the SCDF but couldn't help.
2. Can we have a way to generate the traceId from SCDF that can be associated with each log message, generated from SCDF as well as all the tasks which composes to have a job(using composed task runner).
3. How can we get the values of field set by SCDF in TASK_EXECUTION table like parent_task_id and external_task_id in all the tasks?
4. Can we pass some data from one task (task1) to another task (task2) once the task completes (task1)its execution and let next task (task2) to start?
5. Can we pass all the logs from tasks as well as from SCDF to Kafka Cloud using KafkaAppender?

Please advise.
