Write to s3 from blocking queue java using camel - apache-camel

Question

I have a use case where I want to write in memory Java blocking queue contents using apache camel route to S3. Is this even possible??
The workaround I can think of is to pull records from blocking queue and flush to local file and then to S3 via file-s3 route.
Update:
Route :
fromF("seda:awsquue?concurrentConsumers=3&queue=#NonLimitQueue%s", getSourceId())
.convertBodyTo(byte[].class)
.setHeader(S3Constants.CONTENT_LENGTH, simple("${in.header.CamelFileLength}"))
.setHeader(S3Constants.KEY,simple("${in.header.CamelFileNameOnly}"))
.log(LoggingLevel.INFO, "route started")
.to("aws-s3://" +"bucket"
+ "?amazonS3Client=#s3ClientProfiler&serverSideEncryption=AES256&multiPartUpload=true");
Queue creation in different workflow :
context.registerBean("NonLimitQueue"+sourceId,ArrayBlockingQueue.class, () -> queue);
camelContext.addRoutes(new S3RouteBuilder(sourceId));
queue.add("qqqq");
When route starts it fails with exception :
java.lang.ClassCastException: class java.lang.String cannot be cast to class org.apache.camel.Exchange (java.lang.String is in module java.base of loader 'bootstrap'; org.apache.camel.Exchange is in unnamed module of loader 'app')
at org.apache.camel.component.seda.SedaConsumer.doRun(SedaConsumer.java:171)

at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628)

which I believe is failing at queue.add("qqqq"). How to write to queue explicitly is not clear to me.

Answer 1

camel seda is a blocking queue for apache camel. default queue size is 1000 .you can increase or decrease this size.
from("aws-s3://helloBucket?accessKey=yourAccessKey&secretKey=yourSecretKey")
.to("seda:awsquue");
from("seda:awsquue?concurrentConsumers=3&queue=#NonLimitQueue").
// do something
// for quarkus it is
#ApplicationScoped
public class ConnectionConf {
#Named("NonLimitQueue")
#Produces
public BlockingQueue arrayDeque(){
return new ArrayBlockingQueue(30000);
}
}

What seems to be happening is Camel trying to read "qqqq" as an Exchange... Camel routes can only handle Exchange-objects and not arbitrary data-structures. What you should do is place the stream you wish to use in the body of an Exchange and send that exchange to the queue.
Something to the effect of this:
camelContext.addRoutes(new S3RouteBuilder(sourceId));
Exchange exchange = new DefaultExchange(camelContext);
exchange.getIn().setBody("qqqq");
queue.add(exchange);
