The message is already nested in DeploymentInfo so I thought it's less verbose like this. But please lmk if you think it should still be renamed to DeploymentTaskQueueInfo.

Should we consider a future when we are able to use a different current deployment for different workflow types or task queues? To me it looks like we need a separate Table/Message/API to get all Start/ContinueAsNew records that point to deployments.

We've thought about some of these cases:

  • for task queues, at least on our current roadmap, we'll insist that users create a different deployment series if they want to rollout task queues separately. (Note that we will support the ability to move a task queue from one deployment series to another) We don't see this as being a big burden for such an advanced use case.
  • for workflow types, we've decided to lean on the UpdateWorkflowOptions for these power-user scenarios for now. (or they can create a different deployment series) But you could imagine adding more fine-grained control to the rollout API. (i.e. instead of a single % ramp, we could provide various ramps for different types. Shahab mentioned there could be multi-cursor problems to think about with such, though). In that world, we could keep the high-level status of DEPLOYMENT_STATUS_RAMPING and create a more fine-grained API for power users. So, it seems premature to think too deeply now.

Adding to @drewhoskins-temporal comments, basically we envision eventually adding task queue and workflow type granularity to Rollout so user can ramp them one-by-one. However, setting different current deployment for different workflow types or task queues is not currently on the road map and users should create new deployment series for such cases.

This is going to be roughly sorted based on deployment creation time, decending. Although if a deployment has a very high number of TQs (or very high number of events happening to it) it will CaN and the sort will be mixed up. In reality we are relying on Visibility sort which is based on WF start time.

I prefer to keep this unspecified until we have a guaranteed order in the future.

Something's not right here. I don't see a use case for listing all the deployments, intermixed, regardless of deployment name. The two scenarios I can think of are users asking:
a) what are the deployment series? (or perhaps the current deployment for each series)
b) what's the history of a given deployment series?

If users do want them all in one endpoint, or if we want that for our UI, it would be a list of lists. But that seems puntable for the unblock , here.

I also question the value of an undisclosed, flaky ordering. Users will naturally expect a time-reverse ordering regardless of what we say here.
I would say a total ordering should be a hard requirement.
Is the scenario you mentioned very likely? Is it sufficiently unlikely to ship for the pre-release and then task up the improvement?

I believe the shuffle is sufficiently unlikely and we can fix it after pre-release. It also won't be a total shuffle, one/few over active deployment will be at the top, the fact that they are over active might mean they are also new builds.
Regarding list of lists, I agree such a UI will make sense and likely preferable. This is something I actually tried to bring up and get attention to but was not successful. Hopefully, it will be discussed during UI work and I'll be OK changing the list APIs then.

I can change the name to DeploymentListEntry or DeploymentSummary. Same pattern is used for ListSchedules where we return a abbreviated set of info in the list response:

@mfateev I've been meaning to mention to you--for pre-release, we're planning to ship this lower-level API. We're working on the design for the rollout API for public preview, at which time we will support ramp pre-deploy testing as part of a bigger rollout API. Then, we can deprecate this API.
The team is currently focused on execution, but expect to review the rollout API design in December.

I annotated this and other APIs as "Experimental" in service.proto so it's clear that they all can change or be removed in the next release.

As @drewhoskins-temporal said, this one in particular is merely a low-level placeholder until the rollout API arrives before public preview.
