Smart engine - Ability to start/stop triggers based on engine load

[vijaynalawade]

Current behavior: When runner type is set to POOLED, trigger goroutines are blocked when runner queue is full. Expected behavior: Some mechanism where app triggers can be temporarily stopped when queue is full and started back when queue is relatively empty. What is the motivation / use case for changing the behavior? This feature will help control event flow when actions are slow in execution.
