|`spec.concurrency`| The maximum number of concurrent builds for the pipeline, ranging from`0`, the default, to`14`, ????or unlimited. Define the concurrency when your pipeline has only one trigger. <br>When set to`0`, freezes execution of the pipeline, switching it to maintenance mode. Use this concurrency setting to modify existing pipelines and freeze execution until you complete the changes.|integer| Optional|

|`spec.triggerConcurrency`| The maximum number of concurrent builds per trigger, ranging from`1-15`, or unlimited. Define the trigger concurrency when your pipeline has multiple triggers.| integer| Optional|

|`spec.branchConcurrency`| The maximum number of concurrent builds per branch, ranging from`1-15`, or unlimited. Define the branch concurrency when your pipeline can run builds on different branches.| integer| Optional|

|`spec.priority`| The priority of the pipeline build, determining the order in which the build is queued. The priority can range from`100` (highest priority), to`-100`(lowest priority), with`0` as the default.|

|`spec.triggers.priority` | The priority for the specific trigger determining the order in which the trigger is executed.<br>The priority can range from`100` (highest priority) to`-100` (lowest priority), with`0` as the default.
