camunda-bpm-custom-batch

The goal of this camunda extension is to provide an simple way of using the camunda batch functionality. Camunda Batch could be used to split a huge workload into small asynchronous jobs. With this extension, we want to open the camunda batch functionality to everyone.

Get started

The extension will be published on maven central, so if you are using maven, just add the dependency:

<dependency>
  <groupId>org.camunda.bpm.extension.batch.project</groupId>
  <artifactId>camunda-bpm-custom-batch-core</artifactId>
  <version>0.1-SNAPSHOT</version>
</dependency>

First you have to define an own job handler for working on the single batch data:

@Component
public class SimpleCustomBatchJobHandler extends CustomBatchJobHandler<String> {
  @Override
  public void execute(List<String> data, CommandContext commandContext) {
      logger.info("Work on data: {}", data.get(0));
  }

  @Override
  public String getType() {
      return "simple-batch-handler";
  }
}

Next you have to notify the engine about this job handler, e.g. with spring-boot:

@Bean
public ProcessEnginePlugin customBatchHandlerPlugin(SimpleCustomBatchJobHandler simpleCustomBatchJobHandler) {
  return new CustomBatchHandlerPlugin(Collections.singletonList(simpleCustomBatchJobHandler));
}

Finally, the creation of the batch itself:

CustomBatchBuilder.of(listOfStringData)
 .jobHandler(simpleCustomBatchJobHandler)
 .create();
