Field Detail

ONLY_NRT_REPLICAS

public static String ONLY_NRT_REPLICAS

If the request context map has an entry with this key and Boolean.TRUE as value, prepDistributed(ResponseBuilder) will only include Replica.Type.NRT replicas as possible destination of the distributed request (or a leader replica of type Replica.Type.TLOG). This is used by the RealtimeGet handler, since other types of replicas shouldn't respond to RTG requests
