   I think this is fully described in the comments.
   ```
       /**
        * OAP server could work in different roles.
        */
       public enum Role {
           /**
            * Default role. OAP works as the {@link #Receiver} and {@link #Aggregator}
            */
           Mixed,
           /**
            * Receiver mode OAP open the service to the agents, analysis and aggregate the results and forward the results
            * to {@link #Mixed} and {@link #Aggregator} roles OAP. The only exception is for {@link
            * org.apache.skywalking.oap.server.core.analysis.record.Record}, they don't require 2nd round distributed
            * aggregation, is being pushed into the storage from the receiver OAP directly.
            */
           Receiver,
           /**
            * Aggregator mode OAP receives data from {@link #Mixed} and {@link #Aggregator} OAP nodes, and do 2nd round
            * aggregation. Then save the final result to the storage.
            */
           Aggregator
       }
   ```
