[jira] Commented: (QPID-2732) JMS Client should implement the
reliability option from the new addressing scheme
[ https://issues.apache.org/jira/browse/QPID-2732?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13004162#comment-13004162 ]
Rafael H. Schloming commented on QPID-2732:
-------------------------------------------
I've had a look at this and it seems low risk for inclusion in 0.10.

> Key: QPID-2732
> URL: https://issues.apache.org/jira/browse/QPID-2732
> Project: Qpid
> Issue Type: Improvement
> Components: Java Client
> Reporter: Rajith Attapattu
> Assignee: Rajith Attapattu
> Priority: Minor
>
> The new addressing scheme defines the following reliability modes.
> unreliable: there may be duplicate messages, and there may also be missing messages
> at-most-once: there may be missing messages, but there will be no duplicate messages
> at-least-once: there may be duplicate messages, but there will be no missing messages
> exactly-once: there will be no missing or duplicate messages
> The mapping to the 0-10 protocol is as follows.
> 1. For at-most-once (and unreliable) we need to use accept-mode=none.
> 2. For at-least-once we use non auto-delete (i.e. auto-delete=*false*), and accept-mode=explicit
> 3. exactly-once is not yet supported.
> The default reliability mode is at-least-once.
