Package io.camunda.zeebe.dynamic.config

Class GatewayClusterConfigurationService

java.lang.Object

io.camunda.zeebe.scheduler.Actor

io.camunda.zeebe.dynamic.config.GatewayClusterConfigurationService

All Implemented Interfaces:

ClusterConfigurationUpdateNotifier, AsyncClosable, ConcurrencyControl, AutoCloseable, Executor

public class GatewayClusterConfigurationService
extends Actor
implements ClusterConfigurationUpdateNotifier

The GatewayClusterConfigurationService contains minimal functionality required for the Gateway. The Gateway only listens to ClusterConfiguration changes. It cannot make changes to the configuration. So the service does not run ClusterConfigurationManager, but only contains the ClusterConfigurationGossiper.
