I have ActiveMQ setup via a camel route and i'm consuming messages from a
queue.
My problem is, if i only have 1 consumer that consumer will only consume 1
message every 30 seconds to a minute or so.
If i setup up more concurrent consumers then each consumer will consume a
message until each consumer is consuming, then any messages that come in are
dropped until a consumer becomes free.
Messages are coming in at an average rate of 1 every second, so in order not
to drop any messages i need a ton of threads.
Is there a configuration item(s) i need to set to get this issue resolved.
Even with a route like this:
from("activemq:topic-name").to("stream:out");
the consumers are bound up for anything up to a minute - i'd assumed they'd
just become free straight away.
btw, my configuration currently looks like this:
context = new DefaultCamelContext();
<code>
ActiveMQComponent amqComp = ActiveMQComponent.activeMQComponent();
ActiveMQConnectionFactory amqcf = new
ActiveMQConnectionFactory(ACTIVEMQ_ENDPOINT_URL);
PooledConnectionFactory pcf = new PooledConnectionFactory();
pcf.setMaxConnections(10);
pcf.setConnectionFactory(amqcf);
JmsConfiguration config = new JmsConfiguration();
config.setConnectionFactory(pcf);
config.setConcurrentConsumers(20);
config.setAsyncConsumer(true);
amqComp.setConfiguration(config);
context.addComponent("activemq", amqComp);
RouteBuilder routes = new RouteBuilder() {
@Override
public void configure() throws Exception {
from("activemq:topic-name")
.to("stream:out");
}
};
context.addRoutes(routes);
context.start();
</code>
