Hi Zhangjian, I am a PM from StreamNative and we also had some internal discussions related to this topic. Let me share our ongoing planning:
* We will extract the pulsar admin pkg from the pulsarctl to a separate open repo which will be called pulsar-admin-go under StreamNative. * Will iterate the pulsar-admin-go library by adding more tests, documentation and may also update or fix the existing APIs. * After the pulsar-admin-go library is stable, we will contribute this project to Apache Foundation.
