Replicated Object Adapter

[vsonnathi]

Hi,

In one of the threads almost an year ago:
http://zeroc.com/vbulletin/showthrea...iple+endpoints

it was mentioned that

"What we would like to do in a future release is add the capability to IcePack to support replication. For example, it might be possible to configure a replicated object adapter, in which case the endpoints for all of the replicated adapters with the same name are combined by the locator."

Is this being considered? The above feature will greatly simplify the deployment and configuration on the Client Side. I don't have to change the configuration whenever I add a new Server.

Thanks,
--Venkat.

Yes, we will add this feature. We are currently working on a new product called "IceGrid", which will be the successor of IcePack, with many new features. IceGrid will support large-scale grid computing and Ice deployments. The first release will most likely be available this summer.

In the meantime, you could consider using the IcePack object registry and query interface:
- you register your "replicated" (identical) objects with IcePack (this can be done using descriptors, icepackadmin or programmatically -- see IcePack::Admin::addObjectWithType)
- in your client, use IcePack::Query to retrieve one random object with this type (with IcePack::Query::findObjectByType) or all these objects (with IcePack::Query::findAllObjectsWithType) and randomize yourself.

This offers load-balancing but no automatic failover.

Best regards,
Bernard

Thanks for the quick response. "IceGrid" seems very interesting - looking forward to your summer release. Can you give some details about IceGrid.
