Issue 189: Eliminate JoinConditions 
always evaluating only after all source activities are 
completeStatus: received
Date added: 29 Jan 
2005
Categories: State 
management
Date submitted: 27 January 2005
Submitter: Prasad Yendluri
Document: 
WS-BPEL Working Draft, December, 2004
Description: The BPEL 
specification currently requires that a joinCondition on a target activity be 
evaluated only after all sources activities for the links coming into it are 
complete, whether or not the the joinCondition calls for it. In situations such 
as an activity needs only one of its source activities to be complete (as in the 
case of an implicit-join), it is unnecessary with serious performance 
implications to require that all source activities must be complete prior to 
evaluating the join condition.

Submitter's proposal: The specification must eliminate this built-in 
inefficiency and facilitate evaluation of joinCondition each time an incoming 
link has a status change, *as an option* on the joinCondition or as a 
process/scope level enabler.
