Trying to create multiple khepri clusters in the same Elixir application, using custom RaServerConfig.

[sksar]

I was trying to create multiple khepri clusters using RaServerConfig, in an elixir application, but I can't really find any good documentation regarding the same.

This I am doing beacuse I need khepri to start multiple Ra clusters with different names, but in elixir it is not happening by default. So RaServerConfig is what i was trying to do.

 :khepri.start(".config", %{
      name: "config",
    })

Can anyone guide me ?

Hello! It would be much easier to assist you if you provided your code via a git repository we could clone. 3 lines of code is insufficient.

Please take the time to distill what you are trying to do into a runnable example. If you expect to get support from us for FREE, the least you can do is put some effort into demonstrating your issue.

There is a chance that @the-mikedavis or @kjnilsson can figure this out just by looking at your code.

This is just after 5 minutes of khepri code browsing. Please note the dialyzer specs to determine the correct types for function arguments:

https://github.com/rabbitmq/khepri/blob/main/src/khepri_cluster.erl#L218-L229
https://github.com/rabbitmq/khepri/blob/main/src/khepri_cluster.erl#L245-L274

:khepri.start("/full/path/to/existing/data/dir", :my_khepri_store_1)

To start multiple Kheri stores, you need to call khepri:start() for each of them. This function and its parameters are documented. You can use khepri:start/2 to specify both the data directory and the name of the store:

khepri:start("/path/to/store1", store1),
khepri:start("/path/to/store2", store2),

(I will let you convert that to Elixir)

@sksar we do not take problem definitions such as "it does not work" seriously. Please put together a repository with an executable way to reproduce the behavior or take your questions elsewhere.

mix new /path/to/khepri-question-284
cd /path/to/khepri-question-284
# put together an example
git add .
git commit -m "Some code to reproduce the behavior from rabbitmq/khepri#284"
# push the repo to a public repo on GitHub
# share the link to said public repo

#279 will solve the issue.
I have found the issue. Thank you all.
