>          Components: General
>    Affects Versions: Discovery Impl 1.0.0

>
> The discovery service provides support for whitelisting sources of topology information, but in a cluster where the topology this creates a re-configuration load of order M*(n*(n-1)) where n is the number of nodes in the topology and M is the number of changes. That load rises rapidly as the number of changes and/or nodes increases. 
> To address this there are 2 proposals.
> 1. To provide an SPI exported from the Discovery Impl bundle that allows implementors to implement whitelisting based on the request. This will need to support creating the request and validating the request.
> 2. Embed functionality within the Discovery Impl bundle that supports validation and encryption of topology requests.
