Distributed queries
-------------------
Key: ISPN-200
URL: https://jira.jboss.org/jira/browse/ISPN-200
Project: Infinispan
Issue Type: Feature Request
Components: Distributed Cache, Querying
Reporter: Manik Surtani
Assignee: Manik Surtani
Fix For: 5.1.0.BETA1, 5.1.0.GA
The holy grail of querying.
* Indexes are _never_ shared.
* Each node maintains local indexes for state it is responsible
for (-Dinfinispan.query.indexLocalOnly=true).
* Indexes could be in memory or disk.
* Queries themselves are distributed.
* The query object is built and broadcast to the entire cluster.
* Each node executes the query on its own _local_ index, returning
results.
* The calling node returns a CacheQuery impl that lazily fetches
and collates results from the cluster.
* I expect this Map/Reduce model to perform very well since the
workload is split up and happens in parallel across multiple CPUs
against much smaller (individual) datasets.
* Works with all cache modes, including DIST.
* Need to make sure duplicates are handled, as well as failover.

"Infinispan Cache Manager" option doesn't show up in the drop down menu for "Manually add" function
---------------------------------------------------------------------------------------------------
Key: ISPN-813
URL: https://jira.jboss.org/browse/ISPN-813
Project: Infinispan
Issue Type: Bug
Components: JMX, reporting and management
Affects Versions: 4.2.0.CR2
Reporter: Michal Linhard
Assignee: Manik Surtani
infinispan 4.2.0.CR2
RHQ version: 3.0.0 build number: 59e9341
postgresql 8.4.5
I've setup RHQ with infinispan-jopr-plugin as described here:
http://community.jboss.org/wiki/MonitoringInfinispanwithRHQ
I'm running this on my local machine having these virtual interfaces
192.168.10.101 test1
192.168.10.102 test2
192.168.10.103 test3
192.168.10.104 test4
192.168.10.105 test5
192.168.10.106 test6
test1 - test4 running jboss 5.1.0.GA with infinispan-gridfs-webdav demo (ran with -Dcom.sun.management.jmxremote.port=6991 to 9664 respectively)
test1 - test2 running rhq-agent bound to respective interface
test5 running rhq-server
sucessfully installed RHQ server
sucessfully installed agents test1 test2
sucessfully imported platforms test1 and test2
sucessfully installed infinispan-jopr-plugin, updated agents
tried to manually add Infinispan Cache Manager according to the instructions:
"To add Infinispan instances manually, go to Resources > Platforms > localhost and then click on Inventory. At the bottom of the page, there's a section that says "Manually Add" and next to it there's a drop down list. Open this list, select "Infinispan Cache Manager" and click Ok."
but the option "Infinispan Cache Manager" doesn't appear in the drop down box.
i don't know wheter this is a RHQ bug or plugin bug or wheter there's something wrong with my installation steps.

[JBoss JIRA] Created: (ISPN-359) Affinity accross caches - static or dynamic

Affinity accross caches - static or dynamic
-------------------------------------------
Key: ISPN-359
URL: https://jira.jboss.org/jira/browse/ISPN-359
Project: Infinispan
Issue Type: Feature Request
Components: Distributed Cache
Affects Versions: 4.0.0.Final
Reporter: Tero Heinonen
Assignee: Manik Surtani
Programmable affinity either through:
1) statically (e.g. annotating a certain field as the key for consistent hashing)
- in our case this cannot be based on the hashCode() as the affinity requirement and object identity are not directly related
2) dynamically (e.g. providing a overridable/annotatable consistentHashCode() function)
This would help to assign entities (in multiple Caches), which are needed together in the same nodes (to avoid remote lookups)
