Subject: [bpel4people] NEW ISSUE: Supporting batch operations

Dear all,
as just discussed pls. find below the
summary of the new proposed issue we have just talked about:
TARGET: WS-HumanTask
DESCRIPTION: Task list clients often deal with many human tasks, performing
the same action on them at the same time, e.g., when a user operates on
a selection of several tasks in a UI application. Today in WS-HT this is
accomplished by invoking a particular operation for each single human task
of such list. When dealing with larger numbers of human tasks this involves
a lot of communication between client and server and thus should be optimized.
For example instead of a claim operation
that takes a single task id as an input we may want to offer a batch claim
operation that processes a set of task ids in a single operation.
PROPOSAL / THOUGHTS: Analyse the operations in chapter "6.1 Operations
for Client Applications", and particularly "6.1.1 Participant
Operations", and define which operations are likely to be called for
a set of human tasks and deserve optimization by offering a corresponding
batch operation. Specify these batch operations (input / output / fault
messages). Agree on a naming scheme for batch operations that makes clear
which original operation the are derived from. .
Best regards,
"Make everything as simple as possible,
but not simpler." - Albert Einstein |
