nit: are these indents right?

Yeah, looks like my IDE just reformatted this when it did the renaming.

If we don't have this could we add something like it to TaskMetadata?

Hm, TaskMetadata is also a public class, right? I think we'll need to do something similar in that case, ie add an internal NamedTaskMetadata class that exposes the namedTopology and then you can access it via something like NamedTaskMetadata.extractNamedTopology(TaskMetadata)
It's unfortunate that TaskMetadata has the taskId field as a String, rather than as an actual TaskId object -- not sure what the motivation there was 😕 I might try to do a very small KIP to fix that, and then we won't have to bother with this at all (you can just use the internal NamedTaskId class/method to access the namedTopology

It would be defiantly better to just fix the taskId in taskMetadata :)

Alright, here we are: KIP-740: Use TaskId instead of String for the taskId field in TaskMetadata
That was probably the fastest/easiest KIP I've ever written

I'm going to merge this without another committer +1 since it's a minor PR with mostly renaming/wrapping classes. And the PR build is actually completely green for once 🥳 |

@ableegoldman do we have a KIP for this change since this is public APIs (not a fan to be picky really)... if not, at least we should document in the upgrade guides.
|
@guozhangwang Ah, shoot, I forgot that the interface name would be public of course..I'll just go ahead and revert that change. I believe the internal class name change should be fine but let me know if there's another name you would prefer |

Here: #10713 |
In #10676 we renamed the internal Subtopology class that implemented the TopologyDescription.Subtopology interface. By mistake, we also renamed the interface itself, which is a public API. This wasn't really the intended point of that PR, so rather than do a retroactive KIP, let's just reverse the renaming.

Renames the existing
Subtopologyclass + interface toSubtopologyDescription, since that more closely matches what it is/is used for. Then introduces a newSubtopologyclass which includes basic metadata such as the topic group id and the NamedTopology that this subtopology belongs to, if any.Also adds an internal
NamedTaskIdclass to expose thenamedTopologyof a TaskId outside the package. I realized TaskId is part of the public API, so we can't just add a publicnamedTopology()getter method. I made thenamedTopologyfield protected and removed the getter/moved it to the NamedTaskId class.There are no actual logical changes or features in this PR, it's just a refactoring. Split these changes out to reduce the LOC in the main PRs.
