adjustConfiguration

public static RequestP2PConfiguration adjustConfiguration(RequestP2PConfiguration p2pConfiguration,
                                          SortedMap<PeerAddress,DigestInfo> directHitsDigest)

Adjusts the number of minimum requests in the P2P configuration. When we query x peers for the get() operation and they have y different data stored (y <= x), then set the minimum to y or to the value the user set if its smaller. If no data is found, then return 0, so we don't start P2P RPCs.

Parameters:

p2pConfiguration - The old P2P configuration with the user specified minimum result

directHitsDigest - The digest information from the routing process

Returns:

The new RequestP2PConfiguration with the new minimum result
