Time interval before coordinator starts reassigning segments

Hey,

In the docs, it is mentioned that “if a historical node becomes unavailable and available again within a short period of time, the historical node will start up and serve segments from its cache without any those segments being reassigned across the cluster

Doc link: http://druid.io/docs/latest/design/coordinator.html

I want to know the value of this short period of time and is it configurable??

Thanks!
