ProducerService (Imixs-Workflow Kafka Adapter 2.3.2 API)

java.lang.Object
- org.imixs.workflow.kafka.ProducerService

All Implemented Interfaces:

Serializable
```
public class ProducerService
extends Object
implements Serializable
```
The ProducerService is a Kafka client that publishes workflow events to the Kafka cluster.
The kafka producer is thread safe and sharing a single producer instance across threads will generally be faster than having multiple instances. For that reason we use a @Singleton with @ConcurrencyManagement
The producer consists of a pool of buffer space that holds records that haven't yet been transmitted to the server as well as a background I/O thread that is responsible for turning these records into requests and transmitting them to the cluster. Failure to close the producer after use will leak these resources.
