MDB Transaction Batch Support ----------------------------- Key: JBAS-7270 URL: https://jira.jboss.org/jira/browse/JBAS-7270 Project: JBoss Application Server Issue Type: Feature Request Security Level: Public (Everyone can see) Components: EJB3 Reporter: Clebert Suconic Assignee: Carlo de Wolf When someone is receiving messages, this is a pretty common useCase: Consumer cons = sess.createConsumer(....); Transaction tx = getTheTransactionSomehow); int counter = 0; Message msg = null; try { do { msg = cons.receive(2000); // or a configured timeout if (counter ++ == 1000) tx.commit(); performDBOperations(msg); } while (msg != null); } catch (Exception e) { tx.rollback(); } However, this is not possible over MDBs. You basically have to transact every received message. With the code above, we would instead commit or rollback the entire group. It should be possible to do this kind of batching with MDBs somehow. IMO this should be suggested as part of the Specification, as other systems also have it. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
