Queues – @Daniel Bluhm

• Persistent Queues work

• Needs more – something to add to queue, dequeue

• Actions:

  • @Daniel Bluhmto do a hackmd doc design to meet mediator-centric requirements, ideally with a narrative on push notification handling

  • @Andrew Whiteheadto do a hackmd doc design to meet scalabilty requirements

  • Ideally, incorporated into the above, but if not, a third design doc, covering the use of the event bus with the outbound queuing

  • Possible meeting ahead of next ACA-Pug meeting.

When is the next ACA-Py release?

• Drivers: request for the resolver capability from BPA team, endorser signing functionality

• After those – are we ready?  Other items to add?

• To Do:
  
  

  • SICPA: Tweaks to resolver and docs.

  • DIF Presentation Exchange merge when reviewed and ready.

  • Andrew: 0.7.0-RC1 tag than 0.7.0 tag, optionally branch from there for 0.7.1 if needed (ideally, just tag 0.7.1 on main branch)
