[wsrp-wsia] Issue #19 - Hints for InitEnvironment

[Andre Kramer <andre.kramer@eu.citrix.com>]

Since I originally raised #19 and as I've not seen any follow on discussion on our infamous initEnvironment()/groupID topic since last week's call, I would like to make more concrete a proposal made in the call's lengthy groupID discussion.

 

7.1.1. states: "Since Consumers will not know what entities could benefit from any Producer mediated data sharing, they SHOULD place all entities from a Producer within a single group until a reason is identified for specifying a separate groupID".

 

I agree this is enough to support JSR168 application/shared session scopes by providing each user with a separate (i.e. one) load balanced environment via the groupID argument to initEnvironment(). However, an extra hint from the producer is required in order to load balance a user's Portlets across multiple JSR168/Web Applications and nodes:

 

(Proposal) A producer could include a "String preferredGroupID" (as an optional hint) in an EntityDescription element (or possibly in the EntityType meta data). Consumers could then discover this extra performance related meta data using getEntityDescription() and use it for the groupID in initEnvironment(), as described in 7.4. I believe they are not required to do so, but I would still say "SHOULD" rather than "CAN", which is why this may be more than just a "vendor" extension for JSR168.

 

Hope this helps us further the discussion,

 

Andre

A new version of the issues list.

 

Changes:

 

1. We now have a manageable number of open issues!

 

2. The date whereby a tentative resolution is considered final (due to lack of interest) is now in the list, and not one of the secondary headers. This will help us browse through the list and see whether anything needs to be discussed. BTW, I always set it to two weeks from the time I get a tentative resolution from anybody, and always send an email on that regard to the list to see whether anybody is interested in contesting that resolution.

 

Cheers,

Gil Tayar
