> There is dead code and duplicate code in DistributedZkUpdateProcessor. It
> makes understanding this already complex class more difficult.
> In particular, in getCollectionUrls, there are some unused parameters which
> make the method more complex than it should be. Because it looked a bit
> suspicious, [~broustant] investigated and found it was indeed safe to delete:
> {quote}I looked at the git history.
> This code comes from a refactor in 2019 of DistributedUpdateProcessor to
> extract the code specific to cloud. At that time this method signature
> already contained the boolean.
> Looking earlier, I saw that the boolean was added in 2018 in a commit “Make
> massive improvements to the tests”. It added the boolean and modified the
> single call to pass true. Well, I believe it was a perf optimization to
> always limit to leaders. At that time the intent was clearly to ignore the
> dead code, and I think the dead code should have been removed from the method
> instead of adding this boolean.
> So after looking at the context, I’m +1 to remove this dead code.
