### Search before reporting - [x] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar. ### Motivation IMHO, it's kind of annoying that pulsar-admin functions list doesn't distinguish between running functions and stopped ones. If you have a namespace with a mix of active and stopped functions, there's no way to quickly see which ones are actually running without checking each one individually. This bash one-liner solves that, but it shouldn't be necessary: ``` for function in $(pulsar-admin functions list --namespace $NAMESPACE --tenant $TENANT); do echo $function pulsar-admin functions status --namespace $NAMESPACE --tenant $TENANT --name $function | fgrep running done ``` This is slow and noisy — it makes N+1 API calls just to answer "what's currently running?" It would be much more useful if functions list supported filtering by runtime state directly. ### Solution Add optional filter flags to pulsar-admin functions list: --state flag Filter functions by their running state. ``` # Show only running functions pulsar-admin functions list --tenant public --namespace default --state RUNNING # Show only stopped functions pulsar-admin functions list --tenant public --namespace default --state STOPPED ``` Accepted values: RUNNING, STOPPED (and potentially FAILED, UNKNOWN to cover all states returned by functions status). --long / -l flag (optional, nice-to-have) Show extended output with status inline, similar to ls -l: ``` NAME STATE INSTANCES add-offset-function RUNNING 1/1 topic-filter-key STOPPED 0/1 my-dedup-function RUNNING 3/3 ``` ### Alternatives ### Benefit Eliminates the N+1 API call pattern shown above Makes it practical to monitor function health from scripts and CI/CD pipelines Consistent with other pulsar-admin subcommands that support filtering (e.g., topics list) Reduces operational friction for namespaces with many functions ### Compatibility This is a purely additive change. Without any flags, functions list behaves exactly as it does today. ### Anything else? _No response_ ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
