Hi Shalin,

Looks like in the upgrade section the sentence is incomplete. 

> Pause triggers until actions finish executing and the cool down period expires

> Currently, the cool down period is a fixed period during which events 
> generated from triggers aren't accepted. The cool down starts after actions 
> performed by a previous event finish. But it doesn't protect against triggers 
> acting on intermediate cluster state during the time the actions are 
> executing. Events can still be created and persisted to ZK and will be 
> executed serially once the cool down finishes.
> To protect against, this I intend to modify the behaviour of the system to 
> pause all triggers from execution between the start of actions and end of 
> cool down period. The triggers will be resumed after the cool down period 
> expires.
