Batch Transactions

[Norman Maurer <no...@apache.org>]

Hi all,

is it somehow possible to batch transactions when using activemq
component ? So for example use one transaction for 10 messages.

Thx,
Norman

Hi Norman,

This feature is not part of ActiveMq product but you can using java
language design something like that to process several messages in one
transaction :

public void sendTransacted() throws JMSException {
     //create a default connection - we'll assume a broker is running
    //with its default configuration
    ActiveMQConnectionFactory cf = new ActiveMQConnectionFactory();
    Connection connection = cf.createConnection();
    connection.start();
    //create a transacted session
    Session session = connection.createSession(true,
Session.SESSION_TRANSACTED);
    Topic topic = session.createTopic("Test.Transactions");
    MessageProducer producer = session.createProducer(topic);
    int count =0;
    for (int i =0; i < 1000; i++) {
        Message message = session.createTextMessage("message " + i);
        producer.send(message);
        //commit every 10 messages
        if (i!=0 && i%10==0){
           session.commit();
        }
     }
 }

Thx for Rob Davies code

You can also combine activemq + camel + spring for that :
