Rob Godfrey reassigned QPID-6088: --------------------------------- Assignee: Keith Wall (was: Rob Godfrey) Keith - could you review this change for me? > [Java Client] AMQP 0-8/8/9-1 prefetch should auto expand when receive is > called in a situation where the prefetch buffer is full > -------------------------------------------------------------------------------------------------------------------------------- > > Key: QPID-6088 > URL: https://issues.apache.org/jira/browse/QPID-6088 > Project: Qpid > Issue Type: Improvement > Components: Java Client > Reporter: Rob Godfrey > Assignee: Keith Wall > Fix For: 0.31 > > > 0-8/9/9-1 controls the message prefetch on a per-session basis... however > space if not freed in the prefetch buffer until messages are > acknowledged/committed. > In the case of client-ack / transactional messaging setting the prefetch > value to a low number (e.g. 1) and then attempting to receive() multiple > messages can lead to an effective deadlock whereby the client is waiting for > a message that cannot come because the prefetch buffer is "full". > In the case where the client is explicitly calling receive() through the API > we should expand the prefetch buffer in an attempt to meet their request for > new messages. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org For additional commands, e-mail: dev-h...@qpid.apache.org
