Re: [Engine-devel] Async Task Manager improvements
Hi Yair,
Thanks for the detailed design.
Had some questions
1. Can we think about introducing some DI framework in the Task
Management package. This could be used to inject the DAL, VDS Broker,
Commons etc dependencies. Even the list of providers and TaskStatusEvent
handlers could be registered using this framework.
2. You mention "Several providers that refer to instances of the same
external system type have the same ProviderLogic object. " I'm not sure
I understand this. Could you clarify?
3. Will TaskManager also talk to Job entity and update/end Job if necessary?
4. Are we planning to support custom actions on tasks? That is,
depending on status of task, task can be paused/ resumed/ aborted
/custom action performed etc
thanks

Hi all,
I would like to present you a document I'm working on (still in
draft/working-in-progress mode) of changes to be done at the engine async task manager.
Regarding the detailed design -
The suggested design breaks the task management into two modules - task
management/polling part + command management (in context of completion of
tasks/commands).
The current status of the design is that the design of task management is provided (needs
some polishing) - the command management design will be provided soon.
In addition, we already have some ideas for an alternative design for the task management
part (as suggested by Saggi Mizrahi).
After converging , we will present the complete design.
The reason we're sending the Wiki now is that community members will be aware mainly
to the motivations behind the changes
(Perhaps we should create separate documents for the design and for the
motivation/requirements)
