 - Mail reply from Gregory:

1. What do admins need to know before they implement this feature?
Flow resumption allows High Availability in the Octavia control plane. If an outage occurs while Octavia is processing some tasks, the tasks will be automatically resumed on another available controller.

2. What are the limitations?
Flow resumption uses Redis. With Octavia, Redis doesn't use Sentinel (which is a way to have High Availability in Redis), it means that the Admins have to create only 1 Redis replica for Octavia.

3.Does it involve changing a RHOCP custom resource, or is this a runtime change?
It's a runtime change, in the openstack CR: redis needs to be enabled and we need to add a section in the CR to create a redis DB for Octavia octavia needs to be configured to use this redis DB I'll send you an example of a CR.

4.Who's the QE on the project?
Arkady or Lilach? No idea ATM

5. Anything else to know?
For update considerations, Flow resumption is not enabled by default, but we should recommend/encourage users to enable it.

Does the content require input from multiple DFGs?

 - No

Does the content need to be included in any of the following guides?

 - Only in Octavia public doc
