Class TransactionalIdPatternResolver

java.lang.Object

io.axual.common.resolver.TransactionalIdPatternResolver

All Implemented Interfaces:

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

public class TransactionalIdPatternResolver
extends java.lang.Object
implements TransactionalIdResolver

This class is able to resolve and unresolve patterns for Kafka producer transaction 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 TransactionalIdResolver interface.
