check_config/0 | Checks whether config parameters of the passive load balancing algorithm exist and are valid. |
create_join/4 | Creates a join operation if a node would join at my node with the given key. |
get_number_of_samples/1 | Gets the number of IDs to sample during join. |
get_number_of_samples_remote/2 | Sends the number of IDs to sample during join to the joining node. |

sort_candidates/1 | Sorts all provided operations so that the one with the biggest change of the standard deviation is at the front. |
get_number_of_samples(Conn :: dht_node_join:connection()) -> ok
Gets the number of IDs to sample during join. Note: this is executed at the joining node.
get_number_of_samples_remote(SourcePid :: comm:mypid(), Conn :: dht_node_join:connection()) -> ok
Sends the number of IDs to sample during join to the joining node. Note: this is executed at the existing node.
create_join(DhtNodeState :: dht_node_state:state(), SelectedKey :: rt_chord:key(), SourcePid :: comm:mypid(), Conn :: dht_node_join:connection()) -> dht_node_state:state()
Creates a join operation if a node would join at my node with the given key. This will simulate the join operation and return a lb_op() with all the data needed in sort_candidates/1. Note: this is executed at an existing node.
sort_candidates(Ops :: [lb_op:lb_op()]) -> [lb_op:lb_op()]
Sorts all provided operations so that the one with the biggest change of the standard deviation is at the front. Note: this is executed at the joining node.
process_join_msg(Msg :: comm:message(), State :: any(), DhtNodeState :: dht_node_state:state()) -> unknown_event
check_config() -> boolean()
Checks whether config parameters of the passive load balancing algorithm exist and are valid.
