[Host.ApachePulsar] Contributing provider Apache Pulsar

Juandavi1 commented 3 years ago

Hi,

I would like to contribute to the project by building a provider for Apache Pulsar.

I would like to hear what you think. I saw in the CONTRIBUTING.md file that we need a discussion about the high-level design.

I am new to open source projects. If you can guide me a little, I would appreciate it. Thank you so much

Hi @Juandavi1 , thanks for starting the discussion about the Pulsar provider and helping evolve SMB.

I don't have anything prescriptive in my mind about how to start this. It would be good if you could share your thoughts about what features you'd like to use from Pulsar and what types of messaging you'd like to support in SMB (pub/sub, request-response, queue). It doesn't have to be too long- a few bullet points would do. I have typically implemented these providers on a separate feature branch, initially, I'd started with a simpler scenario like pub/sub, then added request-response or queues at a later point. In the next stages, I have added some transport-specific features/extensions like in the case of ASB or Kafka - the ability to select partitioning key. It all depends on how much time you have. In an ideal world, it's better to have a rich feature set from the start.

Also, it helps provide me feedback if the sample ConsoleApp is extended with your provider - it allows me to understand how do you configure the transport and how well is it then abstracted to the SMB interface.

It might also be good to start with an initial implementation (taking another transport as an example) and adding WiP PR. Ideally, I would like to see in that PR:

a readme added about Pulsar transport on how to configure it and call outs to any outstanding features
sample ComsoleApp is extended to leverage Pulsar
with the sample having some quick instruction dockerfile /kubernetes deployment / helm that would allow us to spin local test env for Pular (not sure if a free cloud instance exists like cloudkarafka).
tests project that correspond the new provider with the integration test for the supported types of communication (see other IT tests).

It doesn't all have to come at once :) Let me know if you need any other guidance.

Cheers,

Hi @zarusz , I've been away for a while. now I have time to start working on this provider.

Thank you very much for the suggestions. I will create the WiP PR.
