Interface GroupResolver

All Superinterfaces:

org.apache.kafka.common.Configurable, Resolver

All Known Implementing Classes:

GroupPatternResolver, LegacyGroupResolver

public interface GroupResolver
extends Resolver

A group resolver can translate Kafka consumer group ids from an application's internal representation to one found externally (or "physically") on Kafka clusters. The conversion from internal to external representation is done through resolveGroup(String). The reverse is done through {link #unresolveGroup(String)}.
