Apache ActiveMQ 5.3 - How to configure a queue to reject duplicate messages?
I need the queue to enforce no-duplicate policy. Is it possible? If so , how? (I've been googling for hours... )
Edit:
The ActiveMQSession implementation has this lines:
// transform to our own message format here
ActiveMQMessage msg = ActiveMQMessageTransformation.transformMessage(message, connection);
// Set the message id.
if (msg == message) {
msg.setMessageId(ne开发者_如何学运维w MessageId(producer.getProducerInfo().getProducerId(), sequenceNumber));
} else {
msg.setMessageId(new MessageId(producer.getProducerInfo().getProducerId(), sequenceNumber));
message.setJMSMessageID(msg.getMessageId().toString());
}
The ActiveMQMessageTransformation is plugable (you can set it) , but the following if statement is a rather incontrovertible .
Any ideas , except changing their code?
ActiveMQ has duplicate message detection built in - how are you defining a duplicate ? If the duplicate has the same messageId - it should be discarded
