Jobs can be stopped by clicking the stop icon on a job in a "Running" state:
You can configure the stopping behavior of the job in the "Advanced" tab. By default, Porter will send
SIGTERM to the job and all child processes of the job, wait for the job to terminate, and send
SIGKILL if the job has not terminated after 30 seconds. The time between
SIGKILL can be configured, and you can avoid sending the signal to all child processes by toggling the "Propagate SIGTERM to child processes" checkbox.
Concurrency Limits for Jobs
You can prevent jobs from running concurrently by toggling the "Allow jobs to execute concurrently" checkbox in the "Advanced" tab. This may be desired if your jobs are writing to data sources, and you wish to prevent duplicate entries.
In general, it is best to ensure your job runs are idempotent.
