Show and tell: TopicConsole, a lightweight desktop client for Apache Pulsar

[yanbo92]

Hi Pulsar community,

I built TopicConsole, an independent cross-platform desktop client for Apache Pulsar. It is a single self-contained binary (about 15 MB) that connects directly to Pulsar, without requiring Docker, a JVM, or a cloud account.

Current workflows include:

• Browse tenants, namespaces, and topics
• Observer mode using a Pulsar Reader, without creating a durable subscription
• Subscription-based consumption with acknowledgement
• Produce messages with keys, values, and headers
• Export message buffers to JSON or CSV
• macOS, Windows, and Linux builds

The latest release is v0.3.0. The project is AGPLv3 licensed and still early, so I would especially appreciate feedback from people running real Pulsar clusters:

1. Which topic inspection or admin workflows are missing?
2. Which authentication or deployment scenarios should I prioritize?
3. Which Pulsar versions and operating systems should I validate next?

Issues and feedback are welcome in the repository. Thanks!
