Class LegacyGroupResolver

java.lang.Object

io.axual.common.resolver.GroupPatternResolver

io.axual.common.resolver.LegacyGroupResolver

All Implemented Interfaces:

GroupResolver, Resolver, org.apache.kafka.common.Configurable

public class LegacyGroupResolver
extends GroupPatternResolver

This class is able to resolve and unresolve patterns for Kafka consumer group ids. It is implemented in much the same way as Kafka (de)serializers, by using a default constructor first and calling configure(Map) later. The parameters passed in during configure() determine the behaviour of the resolver. The class implements the GroupResolver interface.
