There are times when you need to perform maintenance work on a , such as upgrading the version or updating the configuration to add new drivers, but you have running pipelines that you can’t allow to fail. In these cases, you can pause the , which gracefully puts it into a safe state to be worked on. Pausing a will allow it to finish outstanding pipeline tasks before entering a Paused state. Any running or submitted pipelines destined for the during this Paused state will still be shown as active, and any new tasks from those pipelines will be safely queued until the is resumed after the Paused state. While the is paused, users can continue to interact with the pipeline canvas in .

Pausing a Maia runner

  1. On the Runners list, locate the you want to pause and click the three dots ….
  2. Click Pause runner.
  3. Type pause runner in the dialog, to confirm you understand the implications of the action, and then click Pause Runner again.
When paused, the first enters a Pausing state, during which it will complete any pipeline tasks it’s currently executing. Once those tasks are completed, it moves to a Paused state and any queued tasks will be held in the queue until the is resumed. If tasks are executing within a Transaction, the entire transaction will complete before the enters a Paused state.
To be clear: it is individual tasks in progress that are completed, not the entire running pipeline. The pipeline will not progress any further until the resumes and its remaining queued tasks can be executed. The pipeline duration shown in the Pipeline run history will include any time that the pipeline spent waiting for a paused to resume.

​
Restarting a paused Maia runner

When paused, the can be safely restarted on the cloud provider, as described in Restart an AWS ECS Fargate or Restart an Azure .
When a paused is restarted on the cloud provider, the status will remain Paused until the queue automatically resumes or you manually resume the , as described below.

​
Resuming a paused Maia runner

  1. On the Runners list, locate the you want to resume and click the three dots ….
  2. Click Resume runner.
  3. Click Yes resume to confirm.
If a is left in a Paused state for 12 hours, it will automatically resume. A resumed ‘s status will be as follows:
  • If the is actively connected and available, the resumed status will be Running and it will begin to execute queued tasks.
  • If the was stopped during the pause and was never restarted, the resumed status will be Stopped.
  • If the was taken offline, not gracefully stopped during the pause, and never restarted, the resumed status will be Unknown.
If a resumed is not in a running state, then any pipelines that had tasks queued during the pause will timeout after 15 minutes of the resuming, and the pipelines affected will be updated accordingly.
