Andy Taylor commented on ARTEMIS-839:
-------------------------------------
Clebert is correct, the reason ActiveMQ has this is because it has a slow queue
and fast queue on the same journal this kills performance. Artemis doesn't have
this issue so its not something we need to implement from an ActiveMQ parity
point of view. I would either close this Jira and open a new one or change the
summary and description.
> Support multiple backend data stores
> ------------------------------------
>
> Key: ARTEMIS-839
> URL: https://issues.apache.org/jira/browse/ARTEMIS-839
> Project: ActiveMQ Artemis
> Issue Type: New Feature
> Components: Broker
> Reporter: Matt Pavlovich
>
> ActiveMQ 5.x supports multi-kahahdb where destinations matching a certain
> naming convention are stored in separate data stores.
> Artemis should support this to achieve parity with ActiveMQ and other
> commercial brokers, such as Tibco EMS that support multiple back-end data
> stores.
> The 2 primary use cases:
> 1. Increase overall disk I/O by having multiple mount points to allow busy
> destinations to have separate disks
> 2. Separate *.*.*.DLQ destinations in order to avoid the
> journal-cannot-be-cleaned-up issue due to sporadic messages still present
> Note: It was discussed on IRC that #2 may be mitigated with Artemis'
> compaction thread. However, with very large data stores the performance would
> be better with a partitioned data store vs one really large one.
> Enhancement: It would be great if the full path could be specified.
> Currently, in ActiveMQ 5.x the path is automatically generated based on the
> destination name filter and complicates the ability to separate destinations
> due to funky character names on all OS's and filesystems.
> For example, support multiple journal entries ad add an attribute:
>
> * "destination-filter" or similar
> Examples:
>
> * < ... destination-filter="Order.>"
> * < .. destination-filter="Billing.>"
> * < .. destination-filter=">"
>
