title: AWS Glue - starting ETL Job and pending execution
body: <p>Sometimes when I want to run an ETL Job in AWS Glue, it is triggered immediately. But quite often it happens to me that it takes few minutes before ETL Job is doing anything - I see nothing in logs, only "pending execution". Is there any way I can influence it in configuration? Or is it totally up to AWS when it will start the job?</p>
