I think some major relevant parts of the Pulsar docs w.r.t. the requirements are gonna be:

• the Admin API (https://pulsar.apache.org/docs/2.11.x/admin-api-overview/) for stream exploration, topic management and so on
• Pulsar Functions (https://pulsar.apache.org/docs/2.11.x/functions-overview/) regarding the developers workbench
