---------------------------------------
Hi [~davsclaus],
I think we can get started with the documentation. I will take a look at the
examples on the documentation of other components & create the camel-flink
component page.
Can you kindly help me in pointing to the location where the wiki pages for
other components are kept? I checked the camel-website module but couldn't find
them.
> Create Apache Flink Component

> Hello,
> I have created an Apache Flink component for Camel which makes it easier to
> use Flink for analytics. One can use DataSet callbacks with Spring beans/OSGI
> services.
> Using Spring's application context, it can be accessed like
> {noformat}
> @Bean
> public DataSetCallback<Long> countLinesContaining() {
> return new DataSetCallback<Long>() {
> public Long onDataSet(DataSet dataSet, Object... objects) {
> try {
> dataSet.print();
> return new Long(0);
> } catch (Exception e) {
> return new Long(-1);
> }
> }
> };
> }
> @Bean
> public DataSet myDataSet() {
> final ExecutionEnvironment env =
> ExecutionEnvironment.getExecutionEnvironment();
> DataSet<String> text = env.fromElements(
> "Who's there?",
> "I think I hear them. Stand ho! Who's there?");
> return text;
> }
> {noformat}
> The results can be accessed like
> {noformat}
> Long count =
> template.requestBody("flink:dataSet?dataSet=#myDataSet&dataSetCallback=#countLinesContaining",
> pattern, Long.class);
> {noformat}
> Please review & accept my contribution.
