Subject Re: Artemis feature TODO list

> Matt's Artemis Feature TODO:
> 1. Browse needs a page limit (ActiveMQ)
What is this?

> 2. Sparse file support for disk journal (ActiveMQ)
the journal is for what's fit on the memory.

> 3. Separate lock location from storage location for master-slave mode
> (ActiveMQ)
why that? the master-slave on a shared disk needs a lock on the shared
disk. I think we already have that on ARtemis.

> 4. Option to have on-disk index for super large message counts w/ low JDK
> memory (ActiveMQ)

We have that Large Messages support on the core protocol, and we have
Paging mode.

> 5. File-based lease locker for slaves on Windows CIFS shares and other
> non-cluster locking filesystems (IBM MQ)
I think we have that.

+1, can you open a JIRA. it makes sense.

We have been talking about this today.. lets keep that discussion.

I would need more info. Maybe someone else get it?

> 11. Separate consumerTTL and messageTTL for cluster connections (ActiveMQ)
Not sure we need it?

> 12. Destination Policy API (aka Queue Attributes in Artemis) for extending
> destination policy plugins
There's address / queue settings in Artemis. You can configure that
through management or embedded.

> 13. Automatic DLQ naming convention policies (prefix and/or suffix based)
Open a JIRA.

> 14. Missing support for many messaging scheduler features

> 15. Queue attributes to limit max message count and total bytes (IBM MQ,
> Tibco EMS)
We have that already with total bytes.

> 16. Internally defined message headers should have aliases to align to the
> JMS provider standard (“JMS_AMQ_*” vs “_AMQ_”)  IBM MQ, Tibco, Sonic, others

> 17. Client-side url lookup using http endpoint (or other)
you can have the JNDI just like AMQ5

> 18. Inactive Destination Garbage Collection
> 19. Plugins: Message Timestamping, Message Expiry, Broker Path plugin
> 20. JMSXUserId property auto assigned using connected userId
> 21. Anonymous and guest authorizer

> 22. Deliver directly to consumer from memory by limiting total space to

We have that on the core protocol, not an issue.

> 24. Exclusive Consumer and Exclusive Consumer with Message Groups
> 25. Support for subscribing to advisory/event messages (ActiveMQ, IBM MQ,

> 26. Duplex support for cluster-connections (ARTEMIS-838, ActiveMQ)
> 27. Support multiple journal-directory data stores (ARTEMIS-839 ActiveMQ,

> 28. Plugin API for message selector store for Virtual Topic

> 32. Round-robin client producer uri

We have that I think.
