Type Parameters:

K - the key type of messages

V - the value type of messages

public class AxualConsumer<K,V>
extends StaticConsumerProxy<K,V,AxualConsumerConfig<K,V>>

The type Axual consumer. This is a general purpose proxy, that sets up a "proxy chain" using other proxy types. Each proxy adds a specific piece of functionality transparent to the user of this class. Proxy chains are parsed in the AxualConsumerConfig and initialized by the constructor. A typical chain can be configured as follows:

properties.put(AxualConsumerConfig.CHAIN_CONFIG, "SWITCHING;RESOLVING;HEADER");

This configuration sets up a chain containing the SwitchingConsumer --> ResolvingConsumer --> LineageConsumer --> HeaderConsumer --> KafkaConsumer.

Parameters can also be passed to each individual proxy as follows:

properties.put(AxualConsumerConfig.CHAIN_CONFIG, "SWITCHING;LOGGING:name=MyLoggingProxy,level=WARN;RESOLVING;LINEAGE;HEADER");

In this example the LoggingConsumer gets two extra parameters passed in, namely "name" and "level".
